Question

using only loops, no functions and no arrays.

with the heading:

#include <iostream>

using namespace std;

"Write a program that asks the user to enter an odd positive integer. The program reads a value (n) entered by the user and prints an n x n grid displaying a large letter X. The left half should be made up of pluses (+) and the right half should be made with the character "x" and the very center should be an asteric (*). If the value the user entered was not valid, the program should terminate."

Answer 1

Solution:

I have only used loops and if conditions to print the pattern

Code:

#include<iostream>
using namespace std;
int main()
{
        int n;
  cout<<"Enter an odd number: ";
        cin>>n;
        int i,j;
        for(i=1;i<=n;i++)
        {
                for(j=1;j<=n;j++)
                {
                        if(i==n/2+1 && j==n/2+1)
                        {
                                cout<<"*";
                        }
                        if(j<n/2+1 && (j == i || j == (n + 1 - i)))  
                        {
                                cout<<"+";
                        }
                        if(j>n/2+1 && (j == i || j == (n + 1 - i)))  
                        {
                                cout<<"x";
                        }
                        else
                        {
                                cout<<" ";
                        }
                }
                cout<<endl;
        }
}
