warning: deprecated conversion from string constant to ‘char*’ [-Wwrite-strings]

在给构造函数传递字符串的时候经常出现这个问题，这个问题在我接触C++以来一直没头绪解决，今天刚好碰到了一篇文章的解释之后醐醍灌顶，虽然也不是什么大错误，不过还是想记录一下以便日后朋友们和自己能够看到解决问题
先看一下简单的代码吧：

图片在这里插入图片描述
当创建A类对象时，传递字符串给构造函数进行初始化，由于字符串是常量，用char *name指针来接收时，编译器会认为你想要有通过指针来修改字符串的内容，此时就会警告。
解决：
只要在char *name前面加上const限定所传的参数是不可以修改的内容时就不会警告，其实倒也不是特别大的问题，因为直接传递字符串本来就是常量了，一般我们也不会去改变内容，哈哈哈，就先到这里吧

在学习指针定义字符串时，我遇到了 [Warning] deprecated conversion from string constant to ‘char*’ [-Wwrite-strings] 的困扰，为什么会有这个警告？ 为了解决这个问题，我去查阅了很多资料，故在此写下我的第一篇博客，希望能够帮助到大家。 如有错误，希望大家指出。 在这之前，我觉得有必要先说一下指针和数组定义的字符串之间的一些区别 我们先看这样一段代码，大家也可以尝试着运行感受一下 #include<stdio.h> i

deprecated conversion from string constant to 'char *' 今天碰到了这个警告，老老实实的google了一下，以下是收获： 问题是这样产生的，先看这个函数原型： void someFunc(char *someStr); 再看这个函数调用： someFunc("I'm a string!"); 把这两个东西组合起

主程序初始化字符串，是字符串常量, 该字符串的内存分配在全局的const内存区。 而char* 声明了一个指针，而这个指针指向的是全局的const内存区，const内存区当然不会让你想改就改的。所以，如果你一定要写这块内存的话，那就是一个非常严重的内存错误。 修改： char* s 改为 char s[]即可。引用字符串中具体字符的时候*(s+i) 和s[i]都可以。 ps：有关于char* s 和 char s[]的区别见博客。 ...
