C read file line by line

Question

I wrote this function to read a line from a file:

const char *readLine(FILE *file) {

    if (file == NULL) {
        printf(\"Error: file pointer is null.\"         


        

Answer 1

FILE* filePointer;
int bufferLength = 255;
char buffer[bufferLength];

filePointer = fopen("file.txt", "r");

while(fgets(buffer, bufferLength, filePointer)) {
    printf("%s\n", buffer);
}

fclose(filePointer);
