使用单个变量对字符输入进行计数

Count character input using a single variable

本文关键字：字符输入 单个 变量      更新时间：2023-10-16

  1. >我正在尝试计算字符的输入，例如：1 1 1 1 1 2 2 2 2 5 5 5 5 5 5 10 10 10，但我无法摆脱循环并开始新的倒计时。

  2. 当我尝试在屏幕上仅记录总美分数时，cout 在每个周期中总是重复，如何在周期结束时只获得全部金额？

  3. 如何更改代码以简化数字计算？

有什么建议吗？

int main(){
int cent = 0;
int cent_input = 0;
int cent_quantity = 0;
int downgrade_to_one = 0;
do{
while(true){
cout << "nEnter number: " && cin >> cent;
switch(cent){
case 1:
downgrade_to_one =  cent + downgrade_to_one;
if (cent == 0)
cent + 1;
cout << "nYou have: " << downgrade_to_one << " one cent monets.";
break;
case 2:
cent_input = (cent_input + cent) / cent;
cent_quantity = cent_quantity + cent_input;
cout << "nYou have: " << cent_quantity << " two cent monets.";
case 5:
cent_input = (cent_input + cent) / cent;
cent_quantity = cent_quantity + cent_input;
cout << "nYou have: " << cent_quantity << " five cent monets.";
break;
case 10:
cent_input = (cent_input + cent) / cent;
cent_quantity = cent_quantity + cent_input;
cout << "nYou have: " << cent_quantity << " ten cent monets.";
break;
case 25:
cent_input = (cent_input + cent) / cent;
cent_quantity = cent_quantity + cent_input;
cout << "nYou have: " << cent_quantity << " twentyfive cent monets.";
break;
case 50:
cent_input = (cent_input + cent) / cent;
cent_quantity = cent_quantity + cent_input;
cout << "nYou have: " << cent_quantity << " fifty cent monets.";
break;
default:
cout << "nUndefined input!";
}
}
}
while(false);
}

谢谢大家，他们对我的问题投了反对票。我自己解决了这个问题。
