This document discusses various operators in C programming language. It describes arithmetic operators like addition, subtraction, multiplication, division and modulus. It also covers logical/relational operators that are used to compare values, such as ==, !=, >, <, >=, <=. Examples are provided to demonstrate how each operator works and the output obtained when using them in sample code snippets.
C programming operators
- 1. C Programming Operators Operators are the symbol which operates on value or a variable. For example: + is a operator to perform addition.C programming language has wide range of operators to perform various operations.Simple answer can be given using expression 4 + 5 is equal to 9. Here 4 and 5 are called operands and + is called operator. C language supports following type of operators. • Arithmetic Operators • Logical (or Relational) Operators • Bitwise Operators • Assignment Operators • Misc Operators Arithmetic Operators Operator Description Example + Adds two operands A + B will give 30 - Subtracts second operand from the first A - B will give -10 * Multiply both operands A * B will give 200 / Divide numerator by denumerator B / A will give 2 % Modulus Operator and remainder of after an integer division B % A will give 0 #include<stdio.h> #include<conio.h> void main() { int a,b,c,d,e,f,g; clrscr(); printf("Enter the value of A"); scanf("%d",&a); printf("Enter the value of B"); scanf("%d",&b); c=a+b; d=a-b; e=a*b; f=a/b; g=a%b; printf("nThe Sum of A and B is%d",c); printf("nThe Sub of A and B is%d",d); printf("nThe Multiply of A and B is%d",e); printf("nThe Divide of A and B is%d",f); printf("nThe Modulus of A and B is%d",g); getch(); } Relational operators Relational operators are used to compare, logical, arithmetic and character expression. Each of these six relational operators takes two operands. Each of these
- 2. operators compares their left side with their right side. The whole expression involving the relation operator then evaluate to an integer. It evaluates to 0 if the condition is false and 1 if it is true. Suppose that a and b are integer variables whose values are 100 and 4, respectively. Several arithmetic expressions involving these variables are shown below, together with their resulting values. Expression Interpretation Value a<b False 0 a>b True 1 a<=b False 0 a>=b True 1 a==b False 0 a!=b True 1 Assume variable A holds 10 and variable B holds 20 then: Operator Description Example == Checks if the value of two operands is equal or not, if yes then condition becomes true. (A == B) is not true. != Checks if the value of two operands is equal or not, if values are not equal then condition becomes true. (A != B) is true. > Checks if the value of left operand is greater than the value of right operand, if yes then condition becomes true. (A > B) is not true. < Checks if the value of left operand is less than the value of right operand, if yes then condition becomes true. (A < B) is true. >= Checks if the value of left operand is greater than or equal to the value of right operand, if yes then condition becomes true. (A >= B) is not true. <= Checks if the value of left operand is less than or equal to the value of right operand, if yes then condition becomes true. (A <= B) is true. #include<stdio.h> #include<conio.h> void main() { int a,b; clrscr(); printf("Enter the value of A:"); scanf("%d",&a); printf("Enter the value of B:"); scanf("%d",&b); printf("nThe output of A<B is%d",a<b); printf("nThe output of A>B is%d",a>b); printf("nThe output of A<=B is%d",a<=b); printf("nThe output of A>=B is%d",a>=b); getch(); }
