C program to perform addition, subtraction, multiplication and division
C program to perform basic arithmetic operations i.e. addition , subtraction, multiplication and division of two numbers. Numbers are assumed to be integers and will be entered by the user.
In c language when we divide two integers we get integer result for example 5/2 evaluates to 2. As a general rule integer/integer = integer and float/integer = float or integer/float = float. So we convert denominator to float in our program, you may also write float in numerator. This explicit conversion is known as typecasting. Arithmetic operations.
Output of program:
C programming code
#include <stdio.h> main() { int first, second, add, subtract, multiply; float divide; printf("Enter two integers\n"); scanf("%d%d", &first, &second); add = first + second; subtract = first - second; multiply = first * second; divide = first / (float)second; //typecasting printf("Sum = %d\n",add); printf("Difference = %d\n",subtract); printf("Multiplication = %d\n",multiply); printf("Division = %.2f\n",divide); return 0; }
