How do I output * next to numbers

[yoshi circa]

Hello guys I am new to programming and am wondering how I can output a '*' next to a number. also the stars should equal the number so for example:
1 *
2 **
3 ***
and etc. Please help I really just want to know, this is my code.

  #include <iostream>
using namespace std;
int main() {
 char a,b,c,d;

 cout << "Enter Four Digit positive number: "<<endl;
 cout<< "Input = ";
 

     cin>>a;
     cout << a <<endl;
     cin>>b;
     cout << b<<endl;
     cin>>c;
     cout << c <<endl;
     cin>>d;
     cout << d <<endl;

 return 0;
}

std::cout << a << ' ';
for(int i = 0; i < a; ++i) std::cout << '*';
std::cout << std::endl;

or

std::string stars(a, '*');
std::cout << a << ' ' << stars << std::endl;

I'm a little confused..

On what part?

[yoshi circa]

like where to add that piece of code. I was taught without using ' std:: ' so it looked a little odd to me.

std:: is to explicitly say it is part of the std namespace. As far as where to put it, I just showed you examples of how you would do it after getting input for your a variable.

I would personally do something like this:

int const digits = 4;
cout << "Please enter " << digits << " digits" << endl;

int digit = 0;
for(int i = 0; i < digits; ++i)
{
    cin >> digit;
    string temp(digit, '*');
    cout << digit << ' ' << temp << '\n';
}

I made a program for you that does what I think you need. Let me know please.

#include <iostream>
#include <String>

using namespace std;

string choice;
string CHOOSE1();

int a = 1, b = 2, c = 3, d = 4;

int main()
{
		cout << "Enter a letter a, b, c, or d: \n";

		cout << CHOOSE1();
}

string CHOOSE1()
{
	for (int i = 1; i < 1000; i++)
	{

		cin >> choice;

		if (choice == "a")
		{
			cout << "Input = ";
			cout << " 1 *\n";
		}
		else if (choice == "b")
		{
			cout << "Input = ";
			cout << " 2 **\n";
		}
		else if (choice == "c")
		{
			cout << "Input = ";
			cout << " 3 ***\n";
		}
		else if (choice == "d")
		{
			cout << "Input = ";
			cout << " 4 ****\n";
		}
	}
	return 0;
}
