Write a C Program to count Number of Characters in a File

#include <stdio.h> 
#include <stdlib.h> // For exit() 
#define MAX_FILE_NAME 100 
void  main() 
{ 
    FILE* fp; 
    int count = 0; 
    char filename[MAX_FILE_NAME]; 
    printf("Enter file name: "); 
    scanf("%s", filename); 
    // Open the file 
    fp = fopen(filename, "r"); 
    // Check if file exists 
    if (fp == NULL) { 
        printf("Could not open file %s", 
               filename);
