Placement of cpp code

Anyone please help me please…
I made a game that i can close it by pressing X key or ESCAPE key, until this tutorial everything was good, but when i debug it and run it, I cant move the circle to left and right by pressing “A” or “D”, nothing happen by pressing these keys. please show me the way.

It my code:

#include "raylib.h"

int main()
{
    // Window layout
    int width{350};
    int hight{200};
    InitWindow(width, hight, "Halim Shams");

    SetTargetFPS(60);
    while (WindowShouldClose() == false)
    {
        // Circle demations
        int circle_x{175};
        int circle_y{100};

        BeginDrawing();
        ClearBackground(WHITE);
        DrawCircle(circle_x, circle_y, 25, BLUE);

        // Game starts

        if (IsKeyDown(KEY_A))
        {
            circle_x = circle_x - 10;
        }

        if (IsKeyDown(KEY_D))
        {
            circle_x = circle_x + 10;
        }
        
        

        //Game ends
        EndDrawing();
    }
    
}
