头文件：#include<typeinfo>
在上头文件中定义了typeid()操作符可以输出变量的类型。

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

int main(){
    bool a;
    char b;
    short c;
    int d;
    long e;
    float f;
    double g;
    long long h;
    cout<<typeid(i).name()<<endl;
    cout<<typeid(a).name()<<endl;
    cout<<typeid(b).name()<<endl;
    cout<<typeid(c).name()<<endl;
    cout<<typeid(d).name()<<endl;
    cout<<typeid(e).name()<<endl;
    cout<<typeid(f).name()<<endl;
    cout<<typeid(g).name()<<endl;
    cout<<typeid(h).name()<<endl;
    return 0;
}
