如何再返回到主選單 ？ 下面我寫的這個模板你參考下： void dispMenu() { printf("===========選單================\n"); printf("==1 功能1==============\n"); printf("==2 功能2==============\n"); printf("==0 退出==============\n"); } void dispMenu1() { printf("===========選單1================\n"); printf("==1 功能11==============\n"); printf("==2 功能12==============\n"); printf("==0 返回上層選單==============\n"); } void func1() { int cmd; dispMenu1(); scanf("%d",&cmd); while(cmd != 0) { if(cmd ==1) func1(); } } void main() { int cmd; dispMenu(); scanf("%d",&cmd); while(cmd != 0) { if(cmd ==1) func1(); dispMenu(); scanf("%d",&cmd); } }
