Thread: Advice to make my programming better(beginner programmer)

Hello I am a fairly new at programming and have little experience with programming beyond the tutorials on this website(which I think I am on the 15th) and I have been messing around with a few programs that they have had in the the tutorials and expanding them and I was just wondering if there is any bad habits, things I could do to make my programs more organized, or anything else that I should try to fix now before I get to use to programming like that. One of the programs I have expanded on was in the tutorial about typecasting(lesson 11) and was showing how you could turn numbers into ASCII characters. I expanded on the program by giving an option to search for a certain number's character or to show all of the ASCII numbers. Here is what the program looks like

Code:

#include <iostream>


using namespace std;

int allchar()//prints all ASCII characters
{
    int x = 0;//sets x to 0; allows for multiple printings of the ASCII characters
  while(x < 256) {
    cout<< x <<". "<< (char)x <<" ";
    x=x+1;
    //Note the use of the int version of x to
    // output a number and the use of (char) to
    // typecast the x into a character
    // which outputs the ASCII character that
    // corresponds to the current number
  }
  return 0;
}
int picked_char()//User inputs the number to find which character it is
{
    cout<<"Please enter in the characters number you want to find.\n";
    int character;
    cin>>character;
    cin.ignore();
    character=character;
    cout<<character<<". "<< (char)character <<" ";
    return 0;


}




int main()
{
    int again=1;//runs program again
    while(again == 1){


        int choice;//user input for list of ascII or certain one
        int letter;//uesr input for which character to search
        int again_repeat = 1;//makes sure correct input in the while(again_repeat)
        int repeat=1;//repeats while(again ==1) statement till correct input is put in
        int program_repeat;//input to control if program repeats
        while(repeat == 1){
            cout<<"Do you want a list of ASCII characters(press 1)\n";
            cout<<"or search for a certain one(press 2?\n";
            cout<<"\n";
            cin>>choice;
            cin.ignore();
            if(choice == 1){
                allchar();
                cout<<"\n";
                cout<<"\n";
                choice = 0;
                repeat = 0;


            }
            else if (choice == 2){
                picked_char();
                cout<<"\n";
                cout<<"\n";
                choice = 0;
                repeat = 0;
            }
            else{
                cout<<"Invaild Entry. Please re-enter choice.\n";
                cout<<"\n";
                repeat = 1;
            }
        }
        cout<<"If you want to search for another ASCII character press 1.\n";
        cout<<"If you want to exit this program press 2.\n\n";
        while(again_repeat == 1){
            cin>>program_repeat;
            cin.ignore();
            cout<<"\n\n";
            if(program_repeat==1){
                again=1;
                again_repeat = 0;
            }
            else if(program_repeat==2){
                again_repeat = 0;
                again=0;
            }
            else{
                cout<<"Invaild Entry. Please re_enter choice.\n";
            }
        }
    }
    return 0;
}

If any of you have any suggestions on things that might improve my programming now so I will not develop bad programming habits. Oh also sorry if the variables have names that might not make sense could not think of other names for them in the moment.
