C++ -通过自定义数据类型向量中的值匹配和替换元素

#include <iostream>
#include <vector>

struct CustomType {
    int id;
    std::string name;
};

int main() {
    std::vector<CustomType> vec;

    // 添加元素到向量中
    vec.push_back({1, "John"});
    vec.push_back({2, "Alice"});
    vec.push_back({3, "Bob"});

    // 匹配和替换元素
    int targetId = 2;
    std::string newName = "Alex";

    for (auto& element : vec) {
        if (element.id == targetId) {
            element.name = newName;
        }
    }

    // 打印替换后的向量
    for (const auto& element : vec) {
        std::cout << "ID: " << element.id << ", Name: " << element.name << std::endl;
    }

    return 0;
}
