Let’s start here,

Basic Pattern Program List In C++

1. create a rectangle of number of ascending order in C++

``````#include<iostream>
using namespace std;

int main()
{
int row,i,j;
cout<<"Enter number of row: ";
cin>>row;

cout<<endl;

i=1;
while(i<=row) // row
{
for(j=1; j<=row; j++)  // column
{
cout<<" "<<j;
}
cout<<endl;
i++;
}

return 0;
}``````

OUTPUT

``````Enter number of row : 5

1 2 3 4 5
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5``````

2.create a square of numbers of ascending and descending order in C++

``````#include<iostream>
using namespace std;

int main()
{
int row,i,j;
cout<<"Enter number of row: ";
cin>>row;
cout<<endl;

i=1;
while(i<=row) // row of number
{
if(i%2!=0)
{
for(j=1; j<=row+1; j++)
cout<<" "<<j; } else { for(j=row; j>=0; j--)
cout<<" "<<j;
}
cout<<endl;
i++;
}

return 0;
}``````

D E F
G H I J
K L M N O
P Q R S T U``````

16. creating a right-angle using ascii code
