Written in Turbo C++ so dont tell me its very messy because I know it is and this is an assignment that we must stick in to. The source of the problem is in Case 5 int main { . I just dont know how to fix it.

You're trying to declare main within the graph() function. C does not support nested functions so to fix this you have to move the declaration of main() to after the graph() function. So what you're trying is this: Code: void graph() { // ... int main(){ // ... } } and the fix is this: Code: void graph() { // ... } int main(){ // ... } Use of correct indentation will help a lot. I strongly advise putting the code through a code beautifier.
How can I close it ? because case 5 must return to its menu but i cannot put int main(){ inside it because when I will use int main outside case 5 it will just lead to the main menu and not the menu in case 5. I really need it badly. :embarasse Code: #include <stdio.h> #include <conio.h> #include<process.h> #include<dos.h> void graph(); void foo(){ int choice; char z,m; gotoxy (12,12);textcolor(4+BLINK); cprintf("LOADING:");

Ending a case block with a recursive call back into main is a very bad idea. Trust me on this; you definitely do not want to do that. What I mean is this: Code: case 1: // some code (skipped) main(); break; Instead what you need is a loop construct, for example: Code: for (int exitflag=0; !exitflag; ) { // display the menu here switch (choice) { case 1: // case 1 stuff break; case 2: // case 2 stuff break; // other cases case 5: // case 5 stuff break; case 6: exitflag=1; break; } } This will loop until exitflag is set to 1, which is done in case 6. When case 6 is selected, the loop will terminate. After the other cases have run, because of the loop they will return to the point where the menu is displayed, which I think is what you want. Try simplifying the code until you've got the structure sorted out. There is a lot of clutter in the program, and with the lack of formatting it's no surprise you can't figure it out. *I* wouldn't be able to figure it out given the state of the code, and my first step would be to reformat the code. (Actually my first step would be to get an exact spec of the project and find out what the code is supposed to do.)
