Thread: fgets hanging inside if statement

TOPIC: fgets hanging inside if statement for string with spaces support


what's wrong with this code? I believe fgets is hanging. I have tried this code in a separate source file and it works:

Code:

#include <stdio.h>


int main (void)
{
        FILE *fp;
        fp = fopen("groc.txt", "a+");


        char my_string[20];


        fgets(my_string, 20, stdin);
        fputs(my_string, fp);


        printf("You entered: ");
        puts(my_string);


        return 0;
}

This is the modification to the attached (grocery.c). I had scanf functions in here in my original code, this is an old project and i am trying to find out how to pull the old source code from github so I couldnt paste the old code. Anyway, I want support for a string with a space in it (that's why i'm now using fgets) but it's not working correctly inside the if statement but works in it's own separate file, above. i am trying to modify to the add_entry() function. Full source code attached (grocery.c)

Code:

    if (number == 1)
    {
        printf("Enter item to add (%d): ", number);


        fgets(fridge_string, 20, stdin);
        fputs(fridge_string, fp);


        printf("You added: ");
        puts(fridge_string);


        menu();
    }
