beig:

clrscr();

//

if(fp==NULL)

{   change:

fp=fopen(“C:/Calp.txt”,”w”);

puts(“nEnter thefile path::  “);

gets(ch);

fputs(ch,fp);

fclose(fp);

goto beig;

scanf(“%ld”,&y[1]);

break;

}

ch=NULL;

} //year close

//

---

fclose(fp);

puts(“nnRedo calculations?  “);

fflush(stdin);

ca=getch();

//

---

if(ca==’y’||ca==’Y’)

goto beig;

//

---

getch();

}

 

 

//

---

the program ends here

Thank you…….
