Why do we need to cast what malloc returns?

Question

    int length = strlen(src);
    char *structSpace = malloc(sizeof(String) + length + 1);
    String *string = (String*) structSpace;    
    int *string = (int*) s         


        

Answer 1

You should strongly consider casting after using the malloc command because it provides for greater portability and greater compatibility with other parts of your program. If you do not do so, you may run the risk of incompatible data types which could result in errors.
