{                       ///start of main//
FILE *f1,*f2,*f3;     //pointers//
char c;
clrscr();                  // clear the screen//


printf("input text");
f1=fopen("cmb.txt","w");   //open file//
f2=fopen("cmb01.txt","w");
f3=fopen("cmb02.txt","a");
while((c=getchar()) != EOF)
putc(c,f1);                   //copy from one to another//
f1=fopen("cmb.txt","r");
while((c=getc(f1)) !=EOF)
printf("%c",c);                      
fclose(f1);
while((c=getchar()) != EOF) // use while loop for condition//
putc(c,f2);
fclose(f2);
f2=fopen("cmb01.txt","r");
while((c=getc(f2)) !=EOF)   //till not end of file//
printf("%c",c);                  // print all the data//


fclose(f1);                 //close the file//
fclose(f2);
