31. Write a program to create a file, open it, type-in some characters and count the number of characters in a file.

#include <stdio.h>

#include<conio.h>

#include<string.h> main()

{

char ch;

int count=0; FILE *fp; clrscr();

if ( (fp = fopen("vim","w")) == NULL)

{

fprintf(stderr, "Cannot open input file.\n"); getch();

return 1;

}

while ( ( ch =getchar()) != EOF )

{

putc(ch,fp); switch(ch)

{

case ’\n’:

case ’\t’:

case ’ ’:break; default : count++; break;

}

}

printf("no of characters: %d\n", count); fclose(fp);

getch();

return 0;
