I am stumped and have no idea what to do, this is what I have

FILE *file = fopen("file.txt", "r");
int x = someLine;

if (file == NULL) {
    printf("Error! \n");
    strcpy(string, "ERROR");
    return;
}


fclose(file);

this is an answer a simple google search could answer. However, since I'm already typing I'll go ahead and answer this.

you need to read the lines and keep track of how many you have read.

char buf[1000];

while (fgets(buf,1000, file) != NULL)
    printf("%s",buf);

you'll have to look into how fgets works to change this for your use, but this should easily get you to the solution.
