In this post, I am going to write a very simple C program to do Basic Arthmatics. This is an example C program that is useful for Beginners those who want to know how to do Arithmetic operations in C.

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 |
#include <stdio.h> int main() { //Declare variables int number1, number2, addition, subtraction, multiplication, division, modulo; //get the input from user printf("Enter number 1:"); scanf("%d", &number1); printf("Enter number 2:"); scanf("%d", &number2); //adding two number in C addition = number1 + number2; //subtracting two numbers in C subtraction = number1 - number2; //multiplying two numbers in C multiplication = number1 * number2; //Dividing two numbers in C division = number1 / number2; //Get the modulo of two numbers in C modulo = number1 % number2; //print the results printf("\nAddition of %d and %d is equal to %d \n", number1, number2, addition); printf("Subtraction of %d and %d is equal to %d \n", number1, number2, subtraction); printf("Multiplication of %d and %d is equal to %d \n", number1, number2, multiplication); printf("Division of %d and %d is equal to %d \n", number1, number2, division); printf("Modulo of %d and %d is equal to %d \n", number1, number2, modulo); return 0; } |

Just go through the inline comments in the above program to understand it.

Here is the sample output of the above Arithmetic C program:

1 2 3 4 5 6 7 8 9 10 11 12 |
Enter number 1:5 Enter number 2:3 Addition of 5 and 3 is equal to 8 Subtraction of 5 and 3 is equal to 2 Multiplication of 5 and 3 is equal to 15 Division of 5 and 3 is equal to 1 Modulo of 5 and 3 is equal to 2 -------------------------------- Process exited after 1.76 seconds with return value 0 Press any key to continue . . . |

I believe this post would have helped you to understand how to do Addition, Subtraction, Multiplication, Division, and Module in C language. Basically to do the Arithmetics in C programming.
