In this sample C program, we'll learn to read text from a file and store it in a string until enter 'newline' character is encountered.
#include <stdlib.h> // For exit() function
if ((fptr = fopen("program.txt", "r")) == NULL)
printf("Error! opening file");
// Program exits if file pointer returns NULL.
// reads text until newline
printf("Data from the file:\n%s", c);
Data from the file: C programming is awesome.
