1. Create file for content storing.
2. Using required condition for fulfilling the requirement.
3. Display the result on screen.

This C program is successfully compiled and run on a System. Output is shown below.

#include<stdio.h>
void main()
{
    FILE *p;
    char ch;
    int w=1;
    clrscr();
    p=fopen("source","r");
    if(p==NULL)
     {
         printf("file not found");
      }
    else
      {
          ch=fgetc(p);
          while(ch!=EOF)
                 {
                        printf("%c",ch);
                        if(ch==' '||ch=='\n')
                          {
                               w++;
                          }
                               ch=fgetc(p);
                 }
                               printf("\nWords in a file are=%d",w);
     }
                              fclose(p);
                              getch();
