Can anyone help me with this C++ problem?

#include<iostream.h>

	int userInput;
	char userChar;
	char mySpace = ' ';

void input()
{
	cout << "Enter a number:" << endl;
	cin >> userInput;
	cout << "Enter any character:" << endl;
	cin >> userChar;

	if (userInput % 2 == 0)
	{
		userInput++;
	}
}

void print1()
{
		for(int i=1; i <= userInput; i=i+2) 
		{
			for(int j=1; j <= (userInput-i)/2; j++)
			{
				cout << mySpace;
			}
			for(int k=1; k <= i; k++)
			{
				cout << userChar;
			}
			cout << endl;
		}       
}


void print2()
{
		for(int i=userInput; i >= 0; i=i-2)
		{
			for(int j=1; j <= (userInput-i)/2; j++)
			{
				cout << mySpace;
			}
			for(int k=1; k <= i; k++)
			{
				cout << userChar;
			}

			cout << endl;
		}
}

int main()

{                                          
	input();

	print1();

         print2();

	
	return 0;
}
