C - How to use while feof loop to solve empty input file problem?

This is an assignment and my professor only allows us to use feof function to read a file input line by line. Now i have an empty file and I got stuck in an infinite loop.

...
while(!feof(stdin)){
    ...
    char inputLineArray[1000];
    scanf("%[^\n]%*c", inputLineArray);
    ...
}
