Significance of pointer

#1

can’t we just declare ptr as a char instead of char*? if not why? and what is the significance of using pointer(char*) here?

@akash27,

  • Because a char and a pointer to char are two different data types, and thus need to be declared differently.

  • Here, we use char pointer to point to an char array returned by the strtok() function.

can you please explain the program’s control flow with help of a dry run? it would be much appreciated :blush:

@akash27,
Theres nothing to dry run, we are just calling a STL function, it returns a char pointer, we receive it in another char pointer ptr and then print the char array.
If you want to see, how the strtok() function itself works, there is a video on its implementation, please refer to that.
