[問題] inverse，副函式寫法
先貼上我的程式
int inverse(int x)//inverse的副函式
{
int invNum=0;
while(x>0)
{
invNum=x%10;
cout << invNum;
x/=10;
}
}
int main()
{
int num=0,a=0;
cout << "Input a num between 1000~9999：";
cin >> num;
while(num>999 && num<10000)
{
a=inverse(num);
cout << a << endl;
break;
}
system("PAUSE");
}
程式目的是輸入1234，輸出4321，請問各位板友
為什麼我compile出來都會補0呢？(eg.輸入1234，輸出會是43210)
請幫我看看我的程式有哪邊需要修改的>"<
謝謝大家^^

那個...我只是在練習用while作條件判斷^^""
原本的主程式是寫
int main()
{
int num=0,a;
do
{
cout << "Input a num between 1000~9999：";
cin >> num;
}
while(num<999 || num>10000);
a=inverse(num);
cout << a << endl;
system("PAUSE");
}
目的是輸入錯誤的話就會一直重新輸入~
只是因為副程式一直沒寫好，所以在練習while後就乾脆用break跳出= =""
很呆的理由...
