Incorrect reading of row symbols

[meriah]

Main objective: Write a function that translates a positive whole of the decimal place into a binary form, using logical operations, and returns the result as a line.

The following error is made: 0xcccccc RO error in reading the row symbols:

#include <stdlib.h>
#include <fstream>
#include <cstdio>
#include <string.h>
#include <stdio.h>
#include <cstdlib>
#include <cstring>
using namespace std;
char *f(unsigned int a) {

int size = sizeof(int) * 8; // количество бит в числе

char *str = new char[size + 1]; // память под строку по количеству бит

unsigned int p = 1; // переменная для проверки разрядов
for (int i = 0; i &lt; size; i++) {
    if (a &amp; p) str[i] = 1;

    else str[i] = 0; // проверка разряда
    p = p &lt;&lt; 1; // сдвиг единицы влево для проверки следующего разряда
}

for (int i = size - 1; i &gt;= 0; i--)
    if (str[i] == 1) { //пропускаем нули до места, когда впервые появляется 1
        str[i + 1] = '\0';
        break;

    }

for (int i = 0; i &lt;= size / 2; i++) {
    char t = str[i];
    str[i] = str[size - i - 1];
    str[size - i - 1] = str[i];

}

return str;

}
int main() {
int n = 2;
cout &lt;&lt; n &lt;&lt; endl;
char *s = f(n); //вызываем функцию и получаем двоичную запись числа
cout &lt;&lt; s;
delete[]s; //освобождаем память

}

There's a mistake in these places.

char *s = f(n);

char *str = new char[size + 1];

No mistake. the truth and the code doesn't work:

I take it you want the number to be seen in two and put it in line?

You have a mistake here:

if (a & p) str[i] = 1;

Why are you writing? 1Not '1'?

And then the mistakes, the program doesn't work, the empty line.

The idea is that your code should be:

char* f(unsigned int a) {
    const int size = sizeof(int) * 8; // количество бит в числе
    char* str = new char[size + 1]; // память под строку по количеству бит
bool isFirst = false;
int pos = 0;

for (int i = size - 1; i >= 0; i--) {
    if ((a & (unsigned int)(1 << i)) && !isFirst)
        isFirst = true;

    if (isFirst) {
        str[pos] = (a & (unsigned int)(1 << i)) ? '1' : '0';

        pos += isFirst ? 1 : 0;
    }
}

str[pos] = '\0';

return str;
