& operator question

Remember a string of characters is accessed trough a pointer, so it is logical that if you feed a pointer to char to cout it will print the string, or more specific the memory from the pointed location until it finds a null character "\0", if you want to get the memory location you might have to do some casting before cout like so:

// in main
char symbol = 'a';
int nMemorylocation = (int) &symbol
cout << nMemorylocation << endl;
  

not sure if works, but something like that is what you have to do.

Edit:
oh yeah, there are some casting statements for cout, but I dont remember those, I think HEX,OCT,DEC or something, in any case I stick to good old trusty printf

void main(){
char* symbol = "b";
cout << &symbol << endl;
}

Thanks for the replies.

Now I have this...

char symbol= ''a'';
char s[] = "a";
int nMemorylocation = (int) &symbol
cout << nMemorylocation << endl; //6553091, I non valid location
cout << &s << endl; //0063FE01, a valid location

I know when doing char s[]="a" I am making a string of
characters. And I can retrieve the memory location of the
first character in this string with &S.
But when I want do retrieve the memory location of the first and only character in the character variable "symbol", I do not get
a valid memory address (I might be wrong though).

Again thanks for the replies. All comments are helpful.

#include <iostream>

using namespace std;
int main(int argc, char *argv[])
{
	char *a = "a";
	int &address = (int &)(*a);
	cout << "Character: " << a << endl
		<< "Address: 0x" << &address << endl;
	return 0;
}
 

Or instead of storing an extra integer, just cast the pointer to a void pointer, then no special processing will be done:

main
{
char symbol = ''b'';
cout (void *)&symbol << endl;
}

My question has been answered.

Thanks.

FrikkaSoft: you might want to learn you''re hexadecimal to decimal conversion.

6553091 = 0x0063fe03.

6553091 = decimal.
0x0063fe03 = hex.

To the vast majority of mankind, nothing is more agreeable than to escape the need for mental exertion... To most people, nothing is more troublesome than the effort of thinking.

I know, I am extremely ashamed in the moment
I think my effort of thinking was lacking during that post by Kwizatz. Well...
