Homebrew Help with C++ coding for 3DS

[TetrisKid48]

Hey, I was working on a homebrew project (text-based game) and had a problem. When I run the program, it immediately runs through all the code and if statements to check if buttons are pressed, therefore outputting the first text then ending and crashing instantly. How would I wait for the A or B button to be pressed to continue?

#include <3ds.h>
#include <stdio.h>
#include <iostream>
using namespace std;

int main (int argc, char **argv)
{
    hidInit();
    hidScanInput();
    gfxInitDefault();
    consoleInit(GFX_TOP, NULL);
    u32 kDown = hidKeysDown();
    cout << "Does this code work? \n";
    cout << "Press A for yes and B for no. ";
//i need to pause and wait for an input here
    if (kDown & KEY_A)
    {
         goto label2;
    }
    if (kDown & KEY_B)
    {
         goto labelinc;
    }

Thanks for any help!

Try this

#include <3ds.h>
#include <stdio.h>
#include <iostream>
using namespace std;

int main (int argc, char **argv)
{
    gfxInitDefault();
    consoleInit(GFX_TOP, NULL);
   
    cout << "Does this code work? \n";
    cout << "Press A for yes and B for no. ";

    while (aptMainLoop())
    {
        gspWaitForVBlank();
        gfxSwapBuffers();
        hidScanInput();

        u32 kDown = hidKeysDown();
       
        if (kDown & KEY_START)
        {
            break;
        }
       
        if (kDown & KEY_A)
        {
            goto label2;
        }
       
        if (kDown & KEY_B)
        {
            goto labelinc;
        }
       
    }
   
    gfxExit();
    return 0;
}

This should solve your problem

Put it in a loop
You should also avoid using goto
