Sale I can not convert string to const char

#include <iostream>
#include <cstdlib>
#include <ctime>
#include <string>
#include <windows.h>
#include "MMSystem.h"

using namespace std;

int main(int argc, char** argv) 
{

    srand(time(0));
    string ra[] = {"demon_0.wav","demon_1.wav","jocker.wav"};

    for (int i = 0; i < 1; i++){
        int random = rand() % 3;
        //cout << ra[random] << endl;
        PlaySound(TEXT(ra[random]),NULL,SND_FILENAME|SND_ASYNC);
        system("pause");

The function PlaySound receives as a first parameter a LPCTSTR

BOOL PlaySound(
   LPCTSTR pszSound,
   HMODULE hmod,
   DWORD   fdwSound
);

When defining your array as string , you must use the function c_str() to give the function PlaySound a pointer to char .

I give you an example of what you should do.

#include <iostream>

using namespace std;

void f( const char *wav )
{
    printf( "%s", wav );
}

int main() 
{

    string ra[] = {"demon_0.wav","demon_1.wav","jocker.wav"};

    f( ra[1].c_str() );

    return 0;
}

In your code, it would be enough to do:

PlaySound(ra[random].c_str(),NULL,SND_FILENAME|SND_ASYNC);
