C++重载加号运算符实现两个结构体的相加
#include<iostream> #include<string> using namespace std; struct S { int a, b; string str; S operator+(const S &others) { S s1; s1.a = this->a + others.a; s1.b = this->a + others.a; s1.str += this->str; s1.str += others.str; return s1; } }; int main() { S s1, s2,s3; s1.a = 5; s1.b = 5; s1.str = "Hello, "; s2.a = 6; s2.b = 6; s2.str = "World!"; s3 = s1 + s2; cout << s3.a << endl; cout << s3.b << endl; cout << s3.str << endl; }
