Hello coders, in this post we will how to write C Program to perform all arithmetic operations. This is a very basic C program.
As you already know that this site does not contain only c programming solutions here, you can also find the solution for other problems.

C Program to perform all arithmetic operations
#include <stdio.h>
void main()
{
int num1, num2;
int sum, diff, mul, div, mod, quo;
printf("Enter first number: ");
scanf("%d", &num1);
printf("Enter second number: ");
scanf("%d", &num2);
sum = num1 + num2;
diff = num1 - num2;
mul = num1 * num2;
mod = num1 % num2;
quo = num1 / num2;
printf("Sum = %d\n", sum);
printf("Difference = %d\n", diff);
printf("Multiply = %d\n", mul);
printf("Modulus = %d\n", mod);
printf("Quotient = %d\n", quo);
}Output
Enter first number: 30 Enter second number: 10 Sum = 40 Difference = 20 Multiply = 300 Modulus = 0 Quotient = 3
C Program to perform all arithmetic operations using function
// C Program to Perform Arithmetic Operations Using Functions
#include <stdio.h>
// Declaring addition function
int addition(int a, int b){
int sum = a + b;
return sum;
}
// Declaring subtraction function
int subtract(int a, int b){
int difference = a - b;
return difference;
}
// Declaring multiplication function
int multiply(int a, int b){
int multiply = a * b;
return multiply;
}
// Declaring division function
float division(float a, float b){
float divide = a / b;
return divide;
}
// Declaring modulus function
float mod(int a, int b){
int rem = a % b;
return rem;
}
int main(){
int num1, num2;
// Asking for input
printf("Enter the first number: ");
scanf("%d", &num1);
printf("Enter the second number: ");
scanf("%d", &num2);
// Displaying output
printf("Arithmetic operations on %d and %d: \n", num1, num2);
printf("Addition: %d\n", addition(num1, num2));
printf("Subtraction: %d\n", subtract(num1, num2));
printf("Multiplication: %d\n", multiply(num1, num2));
printf("Division: %f\n", division(num1, num2));
printf("Modulus: %d\n", mod(num1, num2));
return 0;
}Enter the first number: 20 Enter the second number: 10 Arithmetic operations on 20 and 10: Addition: 30 Subtraction: 10 Multiplication: 200 Division: 2.000000 Modulus: 10
Conclusion
I hope after going through this post, you understand how to write a C Program to perform all arithmetic operations, if there is any case program is not working and showing an error please let me know in the comment section.
