Write a C++ program to print plus star pattern using for loop.
#include<iostream>
using namespace std;
int main()
{
int i, j, k, rows;
cout << "Enter Plus Star Pattern Row = ";
cin >> rows;
cout << "Plus Star Pattern\n";
for(i = 1; i <= rows * 2 - 1; i++)
{
if(i != rows)
{
for(j = 1; j <= rows; j++)
{
if(j == rows)
{
cout << "*";
}
cout << " ";
}
}
else
{
for(k = 1; k <= rows * 2 - 1; k++)
{
cout << "*";
}
}
cout << "\n";
}
return 0;
}

This C++ example prints the plus pattern of a given character using a while loop.
#include<iostream>
using namespace std;
int main()
{
int i = 1, j, k, rows;
char ch;
cout << "Enter Plus Star Pattern Row = ";
cin >> rows;
cout << "Enter Symbol for Plus Star Pattern = ";
cin >> ch;
cout << "Plus Star Pattern\n";
while(i <= rows * 2 - 1)
{
if(i != rows)
{
j = 1;
while( j <= rows)
{
if(j == rows)
{
cout << ch;
}
cout << " ";
j++;
}
}
else
{
k = 1;
while( k <= rows * 2 - 1)
{
cout << ch;
k++;
}
}
cout << "\n";
i++;
}
return 0;
}
Enter Plus Star Pattern Row = 9
Enter Symbol for Plus Star Pattern = &
Plus Star Pattern
