Here is a program in C that illustrates the use of fscanf() to read a text file:
#include <stdio.h>
#include <stdlib.h>
int main()
{
printf("Welcome to DataFlair tutorials!\n\n");
char character;
FILE *fpointer;
if ((fpointer = fopen("C:\\program.txt","r")) == NULL)
{
printf("Error! The file does not exist.");
exit(0);
}
fscanf(fpointer,"%c", &character);
printf("The character is: %c", character);
fclose(fpointer);
return 0;
}
