We all know that Arithmetic operators are used to performing arithmetic operations in C programming language. Before starting verification program here is a list of operators and their functions and examples.

Basic Arithmetic Operators

Operator: +
Meaning: Addition Operator
Example: 10 + 20 = 30

Operator: –
Meaning: Subtraction Operator
Example: 20 – 10 = 10

Operator: *
Meaning: Multiplication Operator
Example: 20 * 10 = 200

Operator: /
Meaning: Division Operator
Example: 20 / 10 = 2

Operator: %
Meaning: Modulo Operator
Example: 20 % 6 = 2

Below is the very basic C language program for the verification of arithmetic operation and it’s operation.

Arithmetic Operations in C

/* C Program to Verify Arithmetic Operator and Operation */
#include <stdio.h>
int main()
{
int num1,num2;
int sum,sub,mult,div,mod;
printf("\nEnter First Number :"); scanf("%d",&num1);
printf("\nEnter Second Number :"); scanf("%d",&num2);
sum = num1 + num2;
printf("\nAddition is : %d",sum);
sub = num1 - num2;
printf("\nSubtraction is : %d",sub);
mult = num1 * num2;
printf("\nMultiplication is : %d",mult);
div = num1 / num2;
printf("\nDivision is : %d",div);
mod = num1 % num2;
printf("\nModulus is : %d",mod);
return(0);
}

OUTPUT
Enter First Number: 20
Enter Second Number: 6
Addition is: 26
Subtraction is: 14
Multiplication is: 120
Division is: 3.3333333 /* Using float in the above program displays decimal values too. */
Modulus is: 2
