Question

How can we initailize a struct pointer in constructor of a class.
Example:

struct my_struct{
    int i; 
    char* name;
}; 
class my_class{ 
    my_struct* s1;
    my_class() {
        // here i want to make s1->i = 10; and s1->name = "anyname" ;  
        // should i assign it like s1->i= 10; and call new for s1->name and strcpy(s1->name "anyname");  
        // it compiles in g++ without any warning/error but gives seg fault at run time  
    }
};

Answer 1

 my_class() {
     s1 = new (my_struct);
     s1->i = 10;
     s1->name = (char *) malloc(strlen("anyname"));
     s1->name = "anyname";
     // here i want to make s1->i = 10; and s1->name = "anyname" ;  
     // should i assign it like s1->i= 10; and call new for s1->name and strcpy(s1->name "anyname");  
     // it compiles in g++ without any warning/error but gives seg fault at run time  
  }


 ~my_class(){
     free(s1->name);
     delete s1;
  }
