In the book in my avatar (this has become my new catch frase), I came across a few things in the section on pointers which they do not clearly explain. Here's an example:
I see that this is an array of characters, but why is it declared like a pointer? I don't understand how this works. Here's the full example from the book:Code:char* szString = "Randy";
Code:// DisplayString - display an array of characters both // using a pointer and an array index #include <cstdio> #include <cstdlib> #include <iostream> using namespace std; int main(int nNumberofArgs, char* pszArgs[]) { // declare a string char* szString = "Randy"; cout << "The array is '" << szString << "'" << endl; // display szString as an array cout << "Display the string as an array: "; for(int i = 0; i < 5; i++) { cout << szString[i]; } cout << endl; // now using typical pointer arithmetic cout << "Display string using a pointer: "; char* pszString = szString; while(*pszString) { cout << *pszString; pszString++; } cout << endl; // wait until user is ready before terminating program // to allow the user to see the program results system("PAUSE"); return 0; }
