Please find an error in the c++ code?

Question

C++ / C#

The program should convert numbers from 10 to binary, but for some reason it doesn't work. Maybe there is some extra included?

#include "stdafx.h"
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <locale>

int main()
{
  setlocale(LC_ALL, "RUSSIAN");
  int denary; //вводимое число в 10-системе
  int power; //наибольшая степень двойки
  int counter; // счётчик циклов

    printf("\n Введите число от 0 до 255     ");
    scanf_s("%d", &denary);
    if (denary > 255)
      {
        printf("\n Ошибка исходных данных\n");
        getchar();
        exit(0);
      }
      power = 128;
      printf("\n");
      for (counter = 1; counter <= 8; counter++);
      {
        if (denary >= power)
          {
            printf("1");
            denary = denary - power;
          }
        else
          {
            printf("0");
            power = power / 2;
          }
      }
      printf("\n Двоичный код числа =%4d \n", denary);
    
    return 0;
}

Answer 1

Remove the semicolon ;at the end of the linefor (counter = 1; counter <= 8; counter++);

Answer 2

Firstly - all the code in the "code" tag!
Secondly, if there are errors in the includes, the program will not compile.
Thirdly - in my opinion you are doing something completely wrong. Algorithmically.

Answer 3

The first error is ; after for
Second - power must be reduced in each iteration.
Well, general inefficiency.

for (power = 128; power > 0; power >>= 1)
  printf((denary & power ? "1" : "0");
