Arithmetic Operations In C


Advertisements

Basic arithmetic operations include addition, subtraction, multiplication and subtraction. They are performed on numerical data types like int, float and double.

Addition operation in C

The example code given below explains addition in C.

#include <stdio.h>

int main() {
   int op1, op2, sum;      // variable declaration
   
   op1 = 5;                // variable definition
   op2 = 3;
   
   sum = op1 + op2;        // addition operation
   
   printf("sum of %d and %d is %d", op1, op2, sum);
}

The output of the program should be −

sum of 5 and 3 is 8

Subtraction operation in C

The example code given below explains subtraction operation in C.

#include <stdio.h>

int main() {
   int op1, op2, sub;      // variable declaration
   
   op1 = 5;                // variable definition
   op2 = 3;
   
   sub = op1 - op2;        // subtraction operation
   
   printf("Output of %d − %d is %d", op1, op2, sub);
}

The output of the program should be −

Output of 5 − 3 is 2 

Multiplication operation in C

The example code given below explains multiplication in C. Asterisk or * is used as multiplication operator.

#include <stdio.h>

int main() {
   int op1, op2, mul;      // variable declaration
   
   op1 = 5;                // variable definition
   op2 = 3;
   
   mul = op1 * op2;        // multiplication operation
   
   printf("Output of %d multiplied by %d is %d", op1, op2, mul);
}

The output of the program should be −

Output of 5 multiplied by 3 is 15

Division operation in C

The example code given below explains division in C.

#include <stdio.h>

int main() {
   int op1, op2, div;      // variable declaration
   
   op1 = 6;                // variable definition
   op2 = 3;
   
   div = 6 / 3;            // division operation
   
   printf("Output of %d divide by %d is %d", op1, op2, div);
}

The output of the program should be −

Output of 6 divide by 3 is 2
