我想在第二個循環中輸入「賬號」。如果我在「While」控制結構中輸入「輸入帳號」。它會在第一個循環中打印兩次。那我該如何解決這個問題?幫助!?雖然控制結構程序!
/* Make a program that will determine if a department store customer has exceeded the
credit limit on a charge account*/
#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
int aNum,Always;
double balance,iTotal,cTotal,cLimit,NewBal;
cout << "Enter account number: ";
cin >> aNum;
while (aNum != -1)
{
cout << "Enter beginning balance: ";
cin >> balance;
cout << setiosflags(ios::fixed | ios::showpoint) << setprecision(2);
cout << "Enter total charges: ";
cin >> iTotal;
cout << setiosflags(ios::fixed | ios::showpoint) << setprecision(2);
cout << "Enter total credits: ";
cin >> cTotal;
cout << setiosflags(ios::fixed | ios::showpoint) << setprecision(2);
cout << "Enter credit limit: ";
cin >> cLimit;
cout << setiosflags(ios::fixed | ios::showpoint) << setprecision(2);
cout << endl;
NewBal = balance + iTotal - cTotal;
if (NewBal >= cLimit) {
cout << "Account: " << setw(9) << aNum << endl;
cout << "Credit limit: " << cTotal << endl;
cout << "Balance: " << setw(9) << balance << endl;
cout << "Credit limit exceeded." << endl;
cout << endl;
}
}
return 0;
}
您好,歡迎來到程序員。儘管有這個名字,但我們並不是這個問題的網站。我們將看到有關遷移到堆棧溢出的情況。祝你有愉快的一天:) – 2012-08-01 02:54:38
哦,對不起,我是新來的。 – 2012-08-01 02:57:34
沒關係 - 我們會將問題標記爲自動遷移到Stack Overflow - 這是此類問題更合適的站點。 – Deco 2012-08-01 03:05:20
