這是我數學測驗計劃的一部分。我嘗試爲我的任務編寫數學測驗，並且想爲我的數學測驗做一個最終報告，如（int report（））所示。當我運行該程序時，它表示title（）（在modeadd（）中）調用的參數太少。當我更改modeadd（）中的title（）與int title（）相同時，我無法返回到菜單並直接轉到report.How我能解決這個問題嗎？我可以將函數的結果帶到另一個函數嗎？
void main()
{
int add, minus, times, divide;
menu(&add, &minus, ×, ÷);
report(add, minus, times, divide);
printf("\n");
system("pause");
}
int menu(add, minus, times, divide)
{
int choice;
printf("\t\t\t\t\t WELCOME TO THE MATH QUIZ.\n\a");
printf("\t\t\t IF YOU ARE READY, ENTER '1' FOR YES. IF NOT, ENTER '2' FOR NO.\n");
printf("\t\t\t\t PLEASE ENTER YOUR CHOICE : ");
scanf("%d", &choice);
rewind(stdin);
while (choice >= 3 || choice <= 0)
{
printf("INVALID NUMBER, PLEASE TRY AGAIN.\n");
printf("PLEASE RE-ENTER AGAIN : ");
scanf("%d", &choice);

感謝您解決我的問題的一部分，但我的主要「錯誤」是意味着去我試圖調試我的程序，它出來的消息說，有一個建立錯誤。然後它說，在report（）中，使用未初始化的局部變量'add'，'minus'，'times'和'divide'。所以，我知道可能會有一些遺漏或錯誤的代碼。但是，我找不到它。我也嘗試在main（），title（），menu（）中添加，減去次數和除法作爲變量，但我也遇到了同樣的問題。所以我想知道我的錯誤在哪裏，我該如何糾正它。 – NewInProgramming
好的。爲了讓你編譯，你需要在report（）中初始化變量add，minus等。爲此，只需爲它們賦值0.（add = 0;）編譯器會抱怨，因爲您試圖在printf中使用這些變量。然而，如果你遵循我的其他建議，這些變量是不需要的。 HTH –
好的。但是當我改變int標題的時候，我也需要改變modeadd（）中的title（）。但是，當我選擇返回到菜單（在modeadd（））中時，這使我無法回到菜單。此外，如果我在mainad中添加while，在nextadd（）中，當我選擇退出程序時，它會再次跳轉到菜單。我需要做些什麼來解決它。 – NewInProgramming
