C program to check whether a number is positive or negative

Write a C program to check whether a number is positive or negative.

  #include <stdio.h>

  int main() {
        float value;

        /* get the input from the user */
        printf("Enter the input value:");
        scanf("%f", &value);

        /* add 1 to the given input */
        value = value + 1;

        /* if the value is 1 or greater than 1, then positive */
        if (value >= 1) {
                printf("%f is positive\n", value - 1);
        } else {
                printf("%f is negative\n", value - 1);
        }

        return 0;
  }

  Output:

  jp@jp-VirtualBox:~/$ ./a.out
  Enter the input value:-.00123
  -0.001230 is negative

  jp@jp-VirtualBox:~/$ ./a.out
  Enter the input value:0.0123
  0.012300 is positive
