c++ - Char Pointer array memory allocation

Question

How the memory allocation is done for a char pointer array and double pointer.

char *s[]={"knowledge","is","power"}; 
char **p;
 p=s;
 cout<<++*p;

In the above code output given by compiler is- nowledge

My question is just , how the values are assigned to pointer p and how it's incremented.

Answer 1

The operators ++ and * have the same precedence and are both right-to-left-associative, which means that the rightmost operator (*) is executed first. The value of *p is a pointer to the first character of the first string. The operator ++ increments it, making it the pointer to the second character of the first string. That's how you get the "nowledge."
