How do I determine if a value is within a range?

Question

I am relatively new to C, I have to do it for school unfortunately and I am having issues with it at the easiest exercises.

Here I have to check if a number is in a cert

Answer 1

It is because you have declared i variable as int and you are taking input as string so when it is checking condition it is getting null value in i variable and not able to enter if block check below code

    #include <stdio.h>

    int main(){

      int i;
        printf("Value to check Interval \n");
        scanf("%d",&i);

      if (i>4 && i<6){
        printf("%d Value is in first interval\n", i);
      }
    }

try compiling your code without if condition i variable will return a null value
