Question

write a program to check whether a int type number is taken as input is positive, negative or zero​

Answer 1

Answer:

We can Code this in two ways:-

C Language:-

1. If....else:-

#include <stdio.h>

int main() {

double num;

printf("Enter a number: ");

scanf("%lf", &num);

if (num <= 0.0) {

if (num == 0.0)

printf("You entered 0.");

else

printf("You entered a negative number.");} else

printf("You entered a positive number.");

return 0;}

• Nested if

#include <stdio.h>

int main() {

double num;

printf("Enter a number: ");

scanf("%lf", &num);

if (num <= 0.0) {

if (num == 0.0)

printf("You entered 0.");

else

printf("You entered a negative number.");

} else

printf("You entered a positive number.");

return 0;}
