Question

Please upload.cpp file only before the time up. The code must contain your name and has proper format. No library function is allowed. Write a program that draws two triangles by using a character 'x as examples below. The program must prompts a user for an integer larger than 2. The user input will then be used to set the size of the output. If a user input an even value, the program will increase it by one before drawing the box Example 1: Input: 3 Output: XXX XXX XX XX х X Example 2: Input: 4 Output: XXXXX XXXXX XOOXX XXXX XXX XOX XX Xox х х Example 3 Input: 1 Please try again! Input: 2 Please try again! Input: 7 Output: XXXXXXXXXXXX XXXXXX XXXXXX XXXXX ХХХХХ XXXX XXXX XXX XXX XX X X XX

#include <iostream> using namespace std; void pyramid( int n){ int i,j; for(i 0; i<n; i++) { X IB for(j = 0; j < (2 * n); j++) { if(i + j <= n 1) cout << else cout << if((i + n) <= j) cout << "X" else cout << } cout << "\n"; } } int main(k int i, j, n; cout<<"Enter a number 3 or more than 3 : "; cin >> n; if(n<=2) { cout<<"pelase try again!"; exit(); } else if(n%2==0) { n=n+1; pyramid(n); } else pyramid(n); return 0; }

Enter a number 3 or more than 3 : 3 XXX x x x X X XX

Enter a number 3 or more than 3 : 4 x x x x x Χ Χ Χ Χ Χ x x x x Χ Χ Χ Χ Χ Χ Χ Χ Χ Χ Χ Χ Χ Χ X

Enter a number 3 or more than 3 : 7 x x x x x x x Χ Χ Χ Χ Χ Χ Χ Χ Χ Χ Χ Χ Χ x x x x x x Χ Χ Χ Χ Χ x x x x x Χ Χ Χ Χ Χ Χ Χ Χ xxx Χ Χ Χ X X x x x

Enter a number 3 or more than 3 : 2 pelase try again!

Enter a number 3 or more than 3 : 1 pelase try again!

#include <iostream>
using namespace std;
void pyramid( int n)
{ int i,j;
for(i = 0; i < n; i++)
{
for(j = 0; j < (2 * n); j++)
{
if(i + j <= n - 1)  
cout << "x";
else
cout << " ";
if((i + n) <= j)  
cout << "x";
else
cout << " ";
}
cout << "\n";
}
}
int main()
{

int i, j, n;
cout<<"Enter a number 3 or more than 3 : ";
cin >> n;
  
if(n<=2)
{
cout<<"pelase try again!";
exit(0);
}
else if(n%2==0)
{
n=n+1;
pyramid(n);
}
else
pyramid(n);
  
  
return 0;
}
