Question from the Language C - Fundamentals test

How should we instantiate the variable “single” to see the message “you are a heart to take”?

#include <stdio.h>

int main() 
    {
        int single;
        if(single)
        {
            printf("you are a heart to take\n");
        } 
        else
        {
        printf("your heart is taken\n");
        }
        return 0;
    }
