How do I refer to a char* value in a struct that is passed to a method with a struct pointer?

Question

I have a struct defined as :

struct B{
  struct B_test *class;
  char* value;
}

how can I print the char value if I have function passing a struct as parameter as shown:

void print(struct B* e){
  ...
} 

Answer 1

For example

puts( e->value );

or

printf( "%s\n", e->value );

provided that the data member value points to an array that contains a string.

Otherwise you need to know the number of actual elements in the pointed array.

If the data member value points to a single character then you can output it for example like

printf( "%c\n", *e->value );

Answer 2

void print(struct B* e){
    printf("%s", e->value);
} 

Accessing elements of a struct through a pointer is done with the -> operator, not the . operator.
