Write a C program to find that the accepted number is negative or positive or zero

Write a C program to check positive, negative or zero using simple if or if else. C program to input any number from user and check whether the given number is positive, negative or zero. Explain, how to find that the accepted number is negative, positive or zero in C programming.

The above approach is easiest way to tackle the problem. However, you might think why check three conditions. Instead we can write the above code with two conditions. First check condition for positive number, then if a number is not positive it might be negative or zero. Then check condition for negative number. Finally if a number is neither positive nor negative then definitely it is zero. There is no need to check zero condition explicitly.

Below is the c program to find whether a number is positive, negative or zero:

Let us code solution of the program.

  •  Program:

#include<stdio.h>
#include<conio.h>
int main()
{
    int a;

    printf("Enter the first value :");
    scanf("%d",&a);

    if(0<a)
    printf("The value is positive");
    else if(0>a)
    printf("The value is negative");
    else
    printf("The value is neither positive or neither negative");
    
    getch();
    return 0;
}

  •  Output:
Enter the first value :7
The value is positive

Enter the first value :56
The value is positive

Enter the first value :0
The value is neither positive or neither negative

  •  Explain:


  1. Input a number from user in some variable say num.
  2. Check if( num < 0 ), then number is negative.
  3. Check if( num > 0 ), then number is positive.
  4. Check if( num == 0 ), then number is zero.
