I'm studying the string type, and I stumbled across char string[]. Its confusing and I don't even know what it is. Its strange that i can't declare a string after I use it, because its using like a variable and it doesn't allow me to declare other strings. So how to add a name to that char array? Here is the code so I hope its understandable what I mean. Thanks.
#include "iostream"
#include "string.h"
using namespace std;
int main(){
char string[] = "hello stackoverflow";
string word("hello stackoverflow"); //cant declare "word"
//because i declare it above, and i want to know how to avoid that..
cout<<word;
cout<<string;
}
the code I'm studying is this:
/* Trim fat from windows*/
#define WIN32_LEAN_AND_MEAN
#pragma comment(linker, "/subsystem:windows")
/* Pre-processor directives*/
#include <windows.h>
#include "string.h"
/* Windows Procedure Event Handler*/
LRESULT CALLBACK WndProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
PAINTSTRUCT paintStruct;
/* Device Context*/
HDC hDC;
/* Text for display*/
char string [] = "hi im a form"; //this is whats i don't understand what //it is
/* Switch message, condition that is met will execute*/
switch(message)
{
/* Window is being created*/
case WM_CREATE:
return 0;
break;
/* Window is closing*/
case WM_CLOSE:
PostQuitMessage('0');
return 0;
break;
/* Window needs update*/
case WM_PAINT:
hDC = BeginPaint(hwnd,&paintStruct);
/* Set txt color to blue*/
SetTextColor(hDC, COLORREF(0xffff1a));
/* Display text in middle of window*/
TextOut(hDC,150,150,string,sizeof(string)-1); //and here why its //only able to declare it as "string" and not as a name
EndPaint(hwnd, &paintStruct);
return 0;
break;
default:
break;
}
return (DefWindowProc(hwnd,message,wParam,lParam));
}

char c_str[] = "hello";
This declares a variable named c_str of type char [6] a.k.a static array of 6 chars initialized with "hello";
std::string cpp_string("hello");
This declares a variable named cpp_string of type std::string initialized with "hello". If you add using namespace std;, then you can use string instead of std::string.
All declarations of a variable must have the same type. You cannot define a variable multiple times.
You should not declare a variable with the same name as a type.
