Most likely cause: the submenu code calls exit() or returns from main, or you expect break to jump out of multiple levels. In C a break only leaves the innermost switch or loop, and exit()/return will terminate the whole program. To return to the main menu you need the submenu to end and control to go back to the main menu loop — either by returning from a submenu function or by setting a flag that breaks the submenu loop.

A simple, robust pattern is: keep the main menu in a loop, implement each submenu as a function that loops until the user chooses “back”, and have that function return to the caller. Avoid exit() inside submenus. Example structure:

#include <stdio.h>

void submenu(void) {
    int ch;
    while (1) {
        puts("Submenu: 1=do  0=back");
        if (scanf("%d", &ch) != 1) { while (getchar() != '\n'); continue; }
        switch (ch) {
            case 1: puts("Do something"); break;
            case 0: return; /* return to main menu */
            default: puts("Invalid");
        }
    }
}

int main(void) {
    int ch;
    while (1) {
        puts("Main menu: 1=submenu  0=exit");
        if (scanf("%d", &ch) != 1) { while (getchar() != '\n'); continue; }
        switch (ch) {
            case 1: submenu(); break;
            case 0: return 0;
            default: puts("Invalid");
        }
    }
}

Troubleshooting tips: if behavior still exits, search for exit(), return statements inside main, or misplaced breaks. Use functions for clarity, or a boolean flag to break outer loops. As advised, when asking for help post a minimal reproducible snippet and any compiler/runtime messages. Also follow ’s naming advice and the guideline pointed to about how to ask clearly so helpers can reproduce the problem.
