            #include<stdio.h>
        
            main()
            {
                FILE *fp;
                int cap = 0, small = 0;
                char ch;
                clrscr();
                fp = fopen("file1.c", "rt");
                while(!feof(fp))
                {
                    ch = fgetc(fp);
                    printf("%c", ch);
        
                    if(ch >= 'A' && ch <= 'Z')
                    {
                        cap++;
                    }
                    if(ch >= 'a' && ch <= 'z')
                    {
                        small++;
                    }
                }
                printf("\n capital latters is %d", cap);
                printf("\n small latters is %d", small);
                getch();
            }
