C++  pattern printing program Example - 1

Given below is a cpp program to print star patterns as shown above:

//program author : Sayantan Bose
#include<iostream>
using namespace std;
//This the function to print the given pattern
void pattern(int noOfLines)
{
    int i,j;
    for(i=1;i<=noOfLines;i++){       //keep a track of the rows
        for(j=1;j<=noOfLines;j++){   //keep a track of the column
            cout<<"* ";
        }
        cout<<endl;
    }
}
//This is the main function
int main()
{
    int n;
    cout<<"Enter the number of lines you want enter"<<endl;
    cin>>n;
    cout<<"The following is the required pattern"<<endl;
    pattern(n);
    return 0;
}

OUTPUT :

Enter the number of lines you want enter

• From the main function the user is taking the required number of lines that needs to be printed
• Then a function "pattern" is called to print the required pattern
• There are two variables name "i" and "j"
• "i" keep a track of number of rows
• "j" keep a track of number of columns

This is also an example of nested loop

You can see the above code execution and output in codeblocks IDE:
