Can someone please explain how c-strings are used in a C++ function call?

Question

If I have a function that contains arguments char *a or char *a[], what are the operations I can perform on them within the function? How do the char pointers work differently than a regular pointer?

Answer 1

A pointer is a pointer, no matter what datatype it references.

When you index values from a pointer, the memory it pointer points to is treated as an array of whatever datatype the pointer represents.

A string is just an array of characters terminated by a null (zero) character.

You can use the C string library to operate on C strings ( strlen , strcpy , strcat , etc ), and you can easily construct a C++ string object by passing it a char* .

Answer 2

char*

is just a pointer to a character, so anything you can do to pointers you can do to character pointers. The only difference from char* and int* is the type of the pointee.
