C program to subtraction two given numbers?

Answer 1

There is nothing to explain much. Here is the code of that kind of application:

#include

int main() {

int firstNum, secondNum, delta = 0;

printf("Please enter first number (a): ");

scanf("%d", &firstNum);

printf("Please enter second number (b): ");

scanf("%d", &secondNum);

delta = firstNum - secondNum;

printf("a - b = %d\n", delta);

return 0;

}

Testing:

Please enter first number (a): 46

Please enter second number (b): 2

a - b = 44

Please enter first number (a): 1

Please enter second number (b): 45

a - b = -44
