#include<bits/stdc++.h>
using namespace std;
int main()
{
    int n;cin>>n;
    cout<<char(n);
    return 0;
}

强制类型转换

强转

#include<bits/stdc++.h>
#define yy return 0;
using namespace std;
int main(){
    int a;cin>>a;cout<<char(a);
    yy
}

主要题意

输入一个数字，输出它相对的 ASCII 码转化的字符。

解题思路

输入数字后，直接强制转换为char类型输出。

上代码！

#include<bits/stdc++.h>
using namespace std;
int a;
int main()
{
    cin>>a;
    cout<<(char)a;
    return 0;
}
