    well i guess its supposed to like this with out functions..but its not working:

    Code:
    # include <iostream>
    
    using namespace std;
    
    int main()
    { 
    	int row, space, num;
    	char ch;
    
    	// Get int and char
    
    	cout << "Enter number of rows: "<< flush;
    	cin  >> num;
    	cout << "Enter a character: "<< flush;
    	cin  >> ch;
    	
    
    	// This is checking if n is odd or even
    	// If even then we add 1 to n to make it odd
    	
    	if (!(num % 2)) 
    	{
    		num++;
    	}
    
    	//This loop is for the upper crest
    
    	space = 0;
    	for (row = 0 ; row <= num ; row++)
    	{
    		
    	
    		for (space = (num /row) -1 ; space < row ; space++)
    		{
    			cout << endl;
    		}
    	
    	}
    
    	//This loop is for the lower crest
    	
    	for (row = num - 1 ; space > 0 ; row--)
    	{
    		cout << ch;
    	
    
    		for (space = 0 ; space < row; space++)
    		{
    			cout << endl;
    		}

    well i guess it should be like this..i figured the relationship out but its still not working..
    Code:
    # include <iostream>
    
    using namespace std;
    
    int main()
    { 
    	int row, space, num;
    	char ch;
    
    	// Get int and char
    
    	cout << "Enter number of rows: "<< flush;
    	cin  >> num;
    	cout << "Enter a character: "<< flush;
    	cin  >> ch;
    	
    
    	// This is checking if n is odd or even
    	// If even then we add 1 to n to make it odd
    	
    	if (!(num % 2)) 
    	{
    		num++;
    	}
    
    	//This loop is for the upper crest
    
    	row = 0;
    	for (row = num - 1; row <= num ; row++)
    	{
    		cout << ch;
    	
    		for (space = (num /row) -1 ; space < row ; space++)
    		{
    			cout <<space; 
    		}
    		cout << ' ';
    		cout << endl;
    	}
    
    	//This loop is for the lower crest
    	
    	for (row = num - 1 ; space > 0 ; row--)
    	{
    		cout << ch;
    	
    
    		for (space = 0 ; space < row; space++)
