C Program For Count A Character In File Using File

#include <stdio.h>
#define MAX_FILE_NAME 100
int main()
{
	FILE* fp;
	// Character counter (result)
	int count = 0;
	char filename[MAX_FILE_NAME];
	// To store a character read from file
	char c;
	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);
		return 0;
	}
	// Extract characters from file
	// and store in character c
	for (c = getc(fp); c != EOF; c = getc(fp))
		// Increment count for this character
		count = count + 1;
	// Close the file
	fclose(fp);
	// Print the count of characters
	printf("The file %s has %d characters\n ",
		filename, count);
	return 0;
