C++学习4——前置递增和后置递增区别

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

int main()
{
    //前置递增和后置递增区别
    
    //前置递增 先让变量+1 然后进行表达式运算
    int a1 = 10;
    int b1 = ++a1 * 10;
    cout << a1 << endl;
    cout << b1 << endl;

    //后置递增 先进行表达式运算，然后再让变量+1
    int a2 = 10;
    int b2 = a2++ * 10;
    cout << a2 << endl;
    cout << b2 << endl;
    system("pause");
    return 0;
