本文介绍了一个简单的C++程序，该程序模拟键盘输入行为，包括大小写切换和字符转换。通过解析不同的输入指令，如“Caps”和“Shift”，程序能够根据当前状态（大写锁定开/关）正确地输出字符。

#include<iostream>
#include<string>
using namespace std;

int main(){
    int n, m;
    string s;
    cin>>n;
    char ch[2];
    for(int i = 0; i < n; i++){//对每个case处理
        cin>>m;
        bool flag = false;
        for(int j = 0; j < m; j++){
            cin>>s;
            if(s == "Caps"){
                flag = !flag;
            }else if(s == "Shift"){
                if(flag == false){
                    cin>>s;
                    strcpy(ch, s.c_str());
                    char temp = (char)(ch[0] - 32);
                    cout<<temp;
                }else{
                    cin>>s;
                    cout<<s;
                }
            }else{
                if(flag == false){
                    cout<<s;
                }else{
                    strcpy(ch, s.c_str());
                    char temp = (char)(ch[0] - 32);
                    cout<<temp;
                }
            }
        }
        cout<<endl;
    }
}
