UC知道一个四则运算的简单程序 (拜托了明天我要交)

1。写一个四则运算的计算器。包括加，减，乘，除（整数）。
2。运算结果保持，并继续进入运算（从0开始）
3。在运行程序前，要先显示
1，application name
2，使用方法
3，制作者名字
4。0不能被除
User Input Program Output
========== ==============
+ 123 Result = 123
+ 52 new Result = 175
x 37 Error: 'x' is not a valid operator
- 175 new Result = 0
+ 10 new Result = 10
/ 5 new Result = 2
/ 0 Error: attempt to divide by zero
* 8 new Result = 16
q (Program should exit)
以下是我朋友帮我写的，说实话我看不太懂：
void Calculator()
{
float Result=0,Operater=0;
char ch;
bool t=true;
cout<<"\n"<<"Application Name";
cout<<"\n"<<"Used Method";
cout<<"\n"<<"Fabricator";
cout<<"\n"<<" User Input Program Output";
cout<<"\n"&l

帮你做一下注释吧：
void Calculator()
{
float Result=0,Operater=0;
char ch; //把运算符号定义为ch
bool t=true; //t=true时继续计算，出错时t=false
cout<<"\n"<<"Application Name";
cout<<"\n"<<"Used Method";
cout<<"\n"<<"Fabricator";
cout<<"\n"<<" User Input Program Output";
cout<<"\n"<<"============= =======================";
while(t) //当t为真时，继续计算
{
cin>>"ch">>Operater; //输入运算符和数值，如+10
switch(ch) //根据符号判断进行何种运算
{
case '+' Result+=Operater;cout<<"new Result is "<<Result;break;
//+号就加上operator
case '-' Result-=Operater;cout<<"new Result is "<<Result;break;
//-号就减去operator
case '*' Result*=Operater;cout<<"new Result is "<&
