A value of type "const char *" cannot be used to initialize an entity of type "char"

Because the const char* and char * types do not match

There are three ways to solve it:

• Use casts:

char str = "hello world";   //错误代码  双引号

char str = (char)"hello world";//正确代码  使用强制类型转换

• Use character arrays for storage first, and then use pointers:

char str[] = "hello world";

• Right-click on the project, select "Properties", select "C/C++", and then in "Language", change "Conform to Mode" to "No".
