C-style string

I have been puzzled by this problem when I learned how to process strings in C language:

 

Char * str1 = "this is a string! ";

Char * str2 = "string ";

Strcpy (str1, str2 );

 

ForProgram". I have been puzzled, and now I have finally figured it out.

 

For strings in C

Char * STR = "this is a string! "; // STR is a String constant, that is, const char *

Char STR [] = "this is a string"; // STR is a string variable.

 

So the correct usage is:

Char str1 [] = "this is a string! ";

Char str2 [] = "string ";

Strcpy (str1, str2 );

 

Such a simple problem has not been clarified ~~~~ Failed! It seems that you have to learn the C language well. What's important is to learn more and use more!
