int chr=0;

int sp=0;

int ln=0;

int tb=0;

FILE *fp;

fp=fopen("welcome.txt","r");

//clrscr();

printf("file handling program\n ");

while((ch=fgetc(fp))!=EOF)

{

chr++;

if(ch=='\n')

ln++;

if(ch=='\t' )

tb++;

if(ch==' ')

sp++;

}

chr=chr-(sp+tb+ln);

printf(" tabs= %d ",tb);

printf(" spaces= %d ",sp);

printf(" lines= %d ",ln);

printf(" chars= %d ",chr);

//getch();

return 0;

}
