翻译:非常量引用的初始值必须为左值 char* p ="abc"; // valid in C, invalid in C++ 在c++中会报错,正确用法: char* p = (char*)"abc"; // OK 或者 charconst *p ="abc"; // OK __EOF__
warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings] 一、错误代码展示 函数定义: voidreadImage(char*inputPath); 函数使用: readImage("C:\\xxxx\\girl.jpg"); 二、原因分析 在上面的方法中,方法的参数需要我们传递一个指针类型的字符。而我们在使用该方法的时候传递的确...
1. warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings] 解决办法:采用第2或3种字符串赋值方式 int main(int argc, char *argv[]) { char str[] = ""; //先把C++中的string常量复制给C语言形式的字符串变量,再将str赋值给char*形式的C语言字符串。 argv[2] = s...
会跳出警告:warning: ISO C++ forbids converting a string constant to 'char*' [-Wwrite-strings] 改成下面会通过warning char* p = (char*)"abc"; // OK 1. 或者改成下面 char const *p = "abc"; // OK 1. 原因解析: 学习c或者c++的时候都知道,如果在赋值操作的时候,等号两边的变量类型不一样...

warning:ISO C++forbids converting a string constant to'char*'[-Wwrite-strings]CStudentStudent1("女"); 原因为: 赋值时两侧的变量类型要一致,不一致的话就会报上述错误。例子中将函数中的常量赋值给了指针变量。 修改为: CStudent(charconst*gender);或 ...
