goto and junping loop by loop c++

Question

im a new programmer and user here. I don't want to use goto in my code because I don't want to be called " a bad programmer". I need your experience to get rid of that.

#include <iostream>
#include <time.h>
using namespace std;
int main()
{
    srand(time(NULL));
    int control = 1;
    char a[50], harf[5][10];
    a[0] = 65 + rand() % 26;
    for (int i = 1; i < 50; i++)
    {
        if (i % 2 == 0)
            a[i] = 65 + rand() % 26;
        else
            a[i] = 97 + rand() % 26;
    come:
        for (int j = 0; j < i; j++)
        {
            if (a[i] == a[j])
            {
                if (i % 2 == 0)
                {
                    a[i] = 65 + rand() % 26;    goto come;
                }
                else
                {
                    a[i] = 97 + rand() % 26;    goto come;
                }
            }
            else
                continue;
        }
        cout << a[i]<<" ";
    }

    system("pause");
}

No need to create a function, replace your "goto" with "j = -1;"
