如何在C ++中使用cin将空格char分配给char变量？

Question

我是C ++的新手，我想制作一个“编码器”（与其他编码器不同）。我发了一篇新文章，因为我听不懂其他所有文章，而且我是C ++的新手。我不知道如何使用scanf或cin.getline。这是我当前的代码：

#include <iostream>
#include <programConfig.cpp>
#include <windows.h>
using namespace std;
int main(){
    for(int times=1;times!=0;times++){
        char option='0', userText;
        string changed=" ";
        cout<<"Please enter your option (1=Encode, 2=Decode): ";
        cin>>option;
        if(option=='1'){
            system("cls");
            cout<<"Enter a string. Type any character other than A-Z to stop: ";
            for(int times=1;times!=0;times++){
                cin>>userText;
                if(userText=='a' || userText=='A'){
                    changed.append("q");
                }else if(userText=='b' || userText=='B'){
                    changed.append("n");
                }else if(userText=='c' || userText=='C'){
                    changed.append("s");
                }else if(userText=='d' || userText=='D'){
                    changed.append("j");
                }else if(userText=='e' || userText=='E'){
                    changed.append("k");
                }else if(userText=='f' || userText=='F'){
                    changed.append("u");
                }else if(userText=='g' || userText=='G'){
                    changed.append("l");
                }else if(userText=='h' || userText=='H'){
                    changed.append("o");
                }else if(userText=='i' || userText=='I'){
                    changed.append("p");
                }else if(userText=='j' || userText=='J'){
                    changed.append("w");
                }else if(userText=='k' || userText=='K'){
                    changed.append("i");
                }else if(userText=='l' || userText=='L'){
                    changed.append("a");

                }else if(userText=='?'){
                    changed.append("(");
                }else if(userText=='!'){
                    changed.append(")");
                }else{
                    break;
                }
            }
            cout<<"Encoded string:"<<changed<<"."<<endl;

                }else if(userText=='='){
                    changed.append(" ");
                }else if(userText=='('){
                    changed.append("?");
                }else if(userText==')'){
                    changed.append("!");
                }else{
                    break;
                }
            }
            cout<<"Decoded string:"<<changed<<"."<<endl;
            pressEnter("");
            system("cls");
        }
    }
    pressEnter("An error occurred that caused the program to jump out of all loops.");
    return 0;
}

这是programConfig.cpp的代码：

#include <iostream>
#include <cstdlib>
using namespace std;
int power(int baseNumber, int powerNumber){
    int result = 1;
    for(int times=0;times<powerNumber;times++){
        result = result * baseNumber;
    }
    cout<<result<<endl;
}
int cube(int cubeNumber){
    cout<<cubeNumber*cubeNumber*cubeNumber<<endl;
}
int add(int firstNumber, int secondNumber){
    cout<<firstNumber+secondNumber<<endl;
}
int subtract(int firstNumber, int secondNumber){
    cout<<firstNumber-secondNumber<<endl;
}
int multiply(int firstNumber, int secondNumber){
    cout<<firstNumber*secondNumber<<endl;
}
int divide(int firstNumber, int secondNumber){
    cout<<firstNumber/secondNumber<<endl;
}
int pressEnter(string errorMessage){
    if (errorMessage==""){
        cout<<"Press Enter to continue."<<endl;
        cin.ignore(10,'\n');
        cin.get();
    }else{
        cout<<errorMessage<<endl;
        cin.ignore(10,'\n');
        cin.get();
    }
}
int printText(string text){
    cout<<text<<endl;
}

但是只要用户输入空格，cin函数就会跳过它。 还有其他功能可以获取用户输入吗？我是C ++的新手，所以请清楚解释...
