add something to startup registry

ok how would i add this little program to startup when i restart the computer..

Code:

#include <isostream>
#int main()
{
std::cout<<"hello world"<<std::end;
return 0;
}
you will i laugh i know , but i am just trying to figure out how to add it so the exe will add to registry current version and startup by its self 
thanks

Put it in your startup group would be the easiest thing to do probably.

no i need it so when its opened ...it puts the registry vaule in regedit

So you want something which worms it's way into the users registry so it restarts itself each time the program runs?

well not worms its way , just when you run this it adds a reg key to autostart when the computer starts....i am just experimenting

What final goal do you have in mind?

Code:

#include <windows.h>

#define RUN_KEY "SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\Run"

int addRunEntry(char *name, char *path);

int main()
{
    addRunEntry("bob", "c:\\niceprogram\\nonmaliciousprogram.exe");
}

int addRunEntry(char *name, char *path)
{
    HANDLE key;
    int len = strlen(path) + 1;
    LONG r = RegOpenKeyEx(HKEY_LOCAL_MACHINE, RUN_KEY, 0, KEY_SET_VALUE, &key);
    
    if (r != ERROR_SUCCESS) {
        // unable to open key for adding values.
        return 1;
    }

    r = RegSetValueEx(key, name, 0, REG_SZ, path, len);
    if (r != ERROR_SUCCESS) {
        RegCloseKey(key);
        // unable to change registry value.
        return 1;
    }
        
    RegCloseKey(key);

    // success
    return 0; 
}
