Arithmetic Operators in C

Arithmetic Operator

They are five arithmetic operators in C.

• + Addition or unary plus
• - Subtraction or unary minus
• * Multiplication
• / Division
• % Modulo operator

These operators can operate on any arithmetic operations in C.

Example Program Of Arithmetic Operators

/*  Example Program For Arithmetic Operators In C Programming Language

// Header Files
#include<stdio.h>
#include<conio.h>

//Main Function
int main ()
{
  // Variable Declaration
  int a = 100;
  int b = 2;
  int c = 25;
  int d = 4;
  int result;
 
  result = a - b; // subtraction  ( Subtraction or unary minus Arithmetic Operator)
  printf ("a - b = %i\n", result);
 
  result = b * c; // multiplication ( Multiplication Arithmetic Operator)
  printf ("b * c = %i\n", result);
 
  result = a / c; // division ( Division Arithmetic Operator)
  printf ("a / c = %i\n", result); 
 
  result = a + b * c; // precedence ( Addition or unary plus Arithmetic Operator)
  printf ("a + b * c = %i\n", result);
 
  printf ("a * b + c * d = %i\n", a * b + c * d); // Mixed
  return 0;
}

Sample Output

a - b = 98
b * c = 50
a / c = 4
a + b * c = 150
a * b + c * d = 300

How It Works

This C program demonstrates Arithmetic Operators. It first prepares the data it needs, then performs the core operation step by step, and finally prints the output shown in the Sample Output above.

1. Declare the variables that hold the program’s data.
2. Print the final result to the console so you can compare it with the sample output.

Try changing the input values and re-running the program to see how the output changes — this is the fastest way to understand how the logic behaves.
