C-Operators

An operator is used to do some operation taht can be performed on data.There are eight types of operators in C to do the operations. thery are



Types of Operators

  • Arithmetic operators

  • Relation operators

  • Logical operators

  • Conditional operators

  • Increment / Decrement operators

  • Bitwise operators

  • Special operators

  • Short hand assignment operators



Arithmetic operators
Arithmetiic operator s are used to do the arithmetic Calculation

The general form is

variable1 AO Variable2
variable -constant(or) variables
AO-Arithmetic operator

OPERATOR OPERATION EXAMPLE

  1.      +   Addition   x=2+2
  2.     -   Subraction   y=10-4
  3.     *   Multiplication   z=2*2
  4.     /   Division   a=8/2
  5.     %   Modulo   b=3%2




Relation operators
Relation operation is used to find out the relationship between two given variable.

The general form is
Operand1 RO Operand2
operand-variables
RO-relational operator


  1.     >   greater than   A > B
  2.     <   less than   A < B
  3.     >=   greater than equal to   A>=B
  4.     <=   less than equal to   A<=B
  5.     ==   equal to   A==B
  6.     !=   not equal to   A!=B




Logical Operator
Logical operation is used to find out the relationship between relational Expression.

The general form is
Operand1 LO Operand2
where the,
operand - variable
LO - Logical Operator

  1.   &&   AND   X&&Y
  2.   ||   OR   X||Y
  3.   !   NOT   X!X=X




Increment / Decrement Operator
Increment Operator
++ is the increment operator. yhis adds 1 to the value contained in the variable.The general form is

Variable ++     ++ variable
Example
1. a++ which is equal to a=a+1
2. ++a which is equal to a=a+1



Decrement Operator
-- is the Decrement operator. this subtracts 1 to the value contained in the variable.The general form is

Variable--     -- variable
Example
1. a-- which is equal to a=a-1
2. --a which is equal to a=a-1

Nested if condition The block of code following the else statement is executed as the condition present in the if statement is false. nested-if. Nested if statements means an if statement inside another if statement syntax if(condition-1) {     if (condition-2)        {         statement        }     else        {         statement block-2;        } } else  {    statementblock-3;  } Flow chart Example for nested if condition in [c-program] #include< stdio.h> void main() {   int a,b,c;   printf("Enter three number");   scanf("%d%d%d",&a,&b,&c);     if(a>b)       {         if(a>c)         ...

Switch statement  switch statement is an extension of if...else statement. This permits any number of branches. The general form is switch(expression) { case 1 statement block-1; break; case 2 statement block-2; break; .............. .............. .............. case n statement block-n; break; default  default statement; break; } next statement; the value of the expression will check with the case 1, case2,...casen if any case will matches then execute that case statement.then it moves to the next statement. flow diagram: Example program: #include<stdio.h> #include<conio.h> void main() { int number; clrscr(); printf("Enter your exam mark"); scanf("%d",&number); switch(number) { case 35: printf("low mark"); break; case 50: printf("better mark"); break; case 90: printf(...
