C Operators
Operators Introduction
An operator is a symbol which helps the user to command the computer to do a certain mathematical or logical manipulations. Operators are used in C language program to operate on data and variables. C has a rich set of operators as listed previously.Classification of Operators
- Arithmetic operators
- Relational Operators
- Logical Operators
- Assignment Operators
- Increments and Decrement Operators
- Conditional Operators
- Bitwise Operators
- Special Operators.
Write a program to Multiply two numbers.
#include<stdio.h>
void main()
{
int a,b,mul;
printf(“Enter the value of a:/n”);
scanf(“%d”,&a);
printf(“Enter the value of b:/n”);
scanf(“%d”,&b);
mul=a*b;
printf(“ Multiplication =%d”,mul);
getch();
}
Arithmetic operators
#include'stdio.h' //include header file stdio.h
void main() //tell the compiler the start of the program
{
int numb1, num2, sum, sub, mul, div, mod; //declaration of variables
scanf(“%d %d”, &num1, &num2); //inputs the operands
sum = num1+num2; //addition of numbers and storing in sum.
printf(“\n Thu sum is = %d”, sum); //display the output
sub = num1-num2; //subtraction of numbers and storing in sub.
printf(“\n Thu difference is = %d”, sub); //display the output
mul = num1*num2; //multiplication of numbers and storing in mul.
printf(“\n Thu product is = %d”, mul); //display the output
div = num1/num2; //division of numbers and storing in div.
printf(“\n Thu division is = %d”, div); //display the output
mod = num1%num2; //modulus of numbers and storing in mod.
printf(“\n Thu modulus is = %d”, mod); //display the output
}
