Subscripted variables are declared by giving the variable name along with the subscript. Example: a 10 Here a is the variable name and 10 is known as the subscripted value through which we can store 10 values in the variable name a. Disadvantages of arrays: The number of elements to be stored in arrays should be known beforehand. An array is static. Insertion and deletion is quite difficult in an array. Allocating more memory than required leads to wastage of memory. Array Subscripts An array subscript is not part of the variable name.
An array subscript allows PTC Mathcad to display the value of a particular element in an array. It is used to refer to a single element in the array. The array subscript is created by using the matrix index operator, or by using the [ key. Usually, the subscript is placed in brackets following the array name. For example, AR[5] identifies element number 5 in an array called AR. If the array is multidimensional, you must specify a subscript for each dimension.
It hangs below its letter or number. It is used when writing chemical compounds. An example of subscript is N 2. Subscripts are commonly used in chemical formulas. A scientist would write the formula for water, H2O, so that the 2 appears lower and smaller than the letters on either side of it.
Function Signature : Function signature basically refers to the number and types of the arguments, it is the part of the prototype. Function Header : It is the first line of a method.
It contains parameters list,return type,access specifier,method name. Parameter list : It is list of parameters which are called during its invoking. Access Specifier : It gives the publicity modes of the method. It can be either public or Private or Protected. Return Statement : The statement which sends value from method to caller program is known as Return statement. Actual Parameter : The parameter that appears in function call statement are called actual parameter.
Formal Parameter : The parameter that appears in function definition are called formal parameter. Pass by Value or Call by Value : Pass by value is the process of passing a copy of actual parameters to the formal Parameters. Pass by reference or Call by Reference : It is the procsee of passing the reference of actual parameters to the formal parameters. Pure Function or Accesor : It is a Function which returns a value to the caller module.
It does not change the state of an object. Impure Function or Mutator : This function may or may not return a value but it changes the state of an object.
Function Overloading : It is the process of defining functions with the same function names but with different number and types of parameters. Static Binding or Early Binding : The System finds the best match of function arguments and parameter list during program compilation.
This phenomenon is known as Static Binding or Early binding. Recursive Function : A function designed in such a way that it calls itself in its body is known as Recursive Function. Parameters : Parameters are the list of variables which are defined in the function definition or function call. Arguments : Arguments are the values passed to the actual parameters by pass by value or pass by reference due its invoking.
Boolean Search : It is a type of searching in which Boolean variable is used to check if the given value is present in the array elements or not. Example Prg : Boolean search. Nested Class : A nested class mean a class within a class.
External Wrapper : External Wrapper is the class declaration enclosing inner part within a pair of curly brackets. Visibilty Modes : Visibilty modes are the Access Specifiers. They deal with the scope of usage of function. They are public,private,protected. Scope of Variable : It determines the visibility of a instant variable throughout the class. It shows the usage of variable in the program. Referencing member methods : The process of referring the member methods from the main class through class objects.
Nested member method : A method within a method is known as nested member method. Invoking a constructor : The process of using a constructor in the program is known as Invoking a Constructor. Default Constructor : A constructor which initializes instant variables of an object with definite values readily defined is known as Default Constructor. Parameterized Constructor : It is a member function with same name as the class name which is used to initialize the object variable by passing parametric values at the time of its execution.
Copy Constructor : This Constructor is used to copy the initial values of the instant variables of an object to the instant variables of another object. Base Class or Super Class : A class from which another class inherits.
Derived Class or Sub Class : A class inheriting properties from another class. Single Inheritance : If a Base class is derived by a single target,then it is known as Single Inheritance.
Multiple Inheritance : When a sub class inherits from multiple Base classes is known as multiple Inheritance. Hierarchical Inheritance : When many Targets inherit from a single base class ,it is known as Hierarchical Inheritance.
Multilevel Inheritance : A target which inherits a Base class can in turn be used as a Base for another target. Such System is known as Multilevel or Nested Inheritance. Hybrid Inheritance : When more than one type of Inheritance Systems are used together,it is known as Hybrid Inheritance. It is a special feature of java which makes it java platform independent. If a Program is written once,it can run on any platform.
Keyword new : It is used to create a new object or a new array. It creates a memory for the variable or object. Keyword this : It is the reference to the current object. Keyword extends : It is used to inherit a sub class to the super class. Type Promotion or Implicit Conversion : The Java compiler converts all operands up to the type of the largest operand.
This type of Conversion is known as type promotion or implicit conversion. Intrinsic data types : These are the primitive data types. They are independent of themselves. Ex: int,float,byte,char,double,etc. Syntax Error or Sematic Error : Error resulting when the grammer rules or the grammer of the programming language are not followed. There may be no errors while compiling but the result or outcome will not be correct.
Runtime Error : These are mistakes other than the syntax and logical error which come during the time of execution. ConditionalStatement : A statement which works on the given condition In the expression is known as Condition Statement. Index : It is the position of the character in a given string. The numbering of characters generally start from 0. Exit Control Loop : This loop checks the given test condition at the end of the loop structure.
It checks the condition after executing the body of the loop. Entry Control Loop : This loop checks the condition and executes the loop only if the condition is true i. NaN : -Not a Number.
When a negative number is given in Math. It results NaN. For instance, a bit int can be treated just as if it were an array of two bit shorts or four 1-byte chars.
Thus in the bit int array, int i[10], i is a subscripted variable where i[0] is the first integer and i[9] is the last. An array stores several values - for example, several numbers - using a single variable name. The programmer can access the individual values with a subscript, for example, myArray[0], myArray[5]. The subscript can also be a variable, for example, myArray[i], making it easy to write a loop that processes all the elements of an array, or some of them, one after another.
The difference between a variable resistor and a rheostat is the same as the difference between six and half a dozen. The difference between a controlled variable and a variable is in their state. A controlled variable is something which is rigid and constant while a variable is liable to change and inconsistent.
The difference between these both is that the control is what stays the same in an experiment and the variable is what changes. The difference between fixed and variable mortgages are that in a fixed mortgage, the rate can not change. In a variable mortgage, the rate changes with time. They are the same. Class Variable is a subset of Variables. The difference between permanent and variable gases is that variable gases change in response to activities in the environment, and permanent gases stay constant.
A coefficient is the number that goes before an element when your balancing the equation. And a subscript is the number after the element. Subscripts are not changed when you balance the equation. The variable. The difference between a variable and a control is that a variable can change during an experiment and a control cannot change. A subscript is a number written below and to the right of a chemical symbol in a formula and a coefficient is a number that is placed in front of a chemical symbol or formula.
