try-catch c++

在C++中，try-catch用于处理异常。通过在try块中编写可能引发异常的代码，然后在catch块中捕获和处理这些异常。以下是一些关于try-catch的范例代码：

范例1：

#include <iostream>

int main() {
    try {
        throw 1;
        throw "error";
    } catch(char *str) {
        std::cout << str << std::endl;
    } catch(int i) {
        std::cout << i << std::endl;
    }
}

这个例子中，我们在try块中抛出了两个异常，一个是整数类型的1，另一个是字符指针类型的"error"。在catch块中，我们根据异常的类型来捕获并处理这些异常。

范例2：

#include <iostream>
#include <exception>

class myexception: public std::exception {
    virtual const char* what() const throw() {
        return "My exception happened";
    }
} myex;

int main() {
    try {
        if(true) //如果，则抛出异常；
            throw myex;
    } catch (std::exception& e) {
        std::cout << e.what() << std::endl;
<span class="em">1</span><span class="em">2</span><span class="em">3</span>
