I'm fairly new to coding and am currently learning C. In my C programming class, my instructor gave us the assignment of writing a program that uses a function which inputs five integers and prints the largest. The program is fairly simple even for me, but I'm facing some problems and was hoping to get some advice.

```
#include <stdio.h>

int largest(int x);

int main(void) {
    int integer1;

    largest(integer1);

    return 0;
}

int largest(int x) {
    int i;

    for (i = 0; i < 5; i++) {
        printf("Enter an integer: ");
        scanf_s("%d", &x);
    }

    return x;
}

```

This is the code that I have written. The main problem that I am having is that in my main method, the IDE tells me to initialize the value of integer1. However, I'm not really sure how to do that because I'm supposed to input the value within the largest() method via the scanf\_s function. How may I solve this?
