C++ program to print solid square star pattern

C++ program to print solid square star pattern

In this article, we will discuss the Program to Print solid square star pattern in C++ programming language

In this post, we are going to learn How to write a program to print  solid square star pattern in C++ language using for loop, while loop and Do-while loop 

Program 1

C++ code to display square pattern Using for loop

This program allows the user  to enter the size and then it will display solid square star pattern using for loop in  C++ programming language

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int i,j,size;

    cout << "Please enter the size" << endl;
    cin>>size;//Takes input from the user for size
    for(i=1; i<=size; i++){
        for(j=1; j<=size; j++){
        cout<<"*";
    }
   cout<<"\n";
    }
    getch();
    return 0;
}

When the above code is executed it produces the following output

Approach

• This program requests the input size
• The input(size) is stored in the variable “size“
• To iterate through the row, run through outer for loop from 1 to given size according to the loop structure for(i=1; i<=size; i++)
  
• To iterate through the row, run through outer for loop from 1 to given size according to the loop structure for(j=1; j<=size; j++) ;
• inside inner loop print star “*”;
• This activity continues until the condition of outer while loop becomes false.

Program 2

C++ code to display square pattern Using while loop

This program allows the user  to enter the size and then it will display solid square star pattern using while loop in  C++ programming language

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int i,j,size;

    cout << "Please enter the size" << endl;
    cin>>size;//Takes input from the user for size
    i=1;
    while(i<=size){
            j=1;
        while(j<=size){
        cout<<"*";
        j++;
    }
   cout<<"\n";
   i++;
    }
    getch();
    return 0;
}

When the above code is executed it produces the following output

 

Approach

• The program requests to input for the “size of the pattern”
• The input stores in the variable “size”
• To iterate through the row, run the outer while loop from 1 to given size according to the loop structure while(i<=size)
  
• To iterate through the column, run the inner while loop from 1 to given size according to the loop structure while(j<=size);
• inside inner loop print “*”
• This activity continues until the condition of outer while loop becomes false

Program 3

C++ code to display square pattern Using do-while loop

This program allows the user  to enter the size and then it will display solid square star pattern using do-while loop in  C++ programming language

#include <iostream>
#include <conio.h>
using namespace std;

int main()
{
    int i,j,size;

    cout << "Please enter the size" << endl;
    cin>>size;//Takes input from the user for size
    i=1;
  do{
            j=1;
        do{
        cout<<"*";
        j++;
    }while(j<=size);
   cout<<"\n";
   i++;
    }  while(i<=size);
    getch();
    return 0;
}

When the above code is executed it produces the following output

Approach

• The program requests to input for the “size of the pattern”
• The input stores in the variable “size”
• To iterate through the row, run the outer do-while loop from 1 to given size according to the loop structure while(i<=size);
  
• To iterate through the column, run the inner do-while loop from 1 to given size according to the loop structure while(j<=size);
• inside inner loop print star
• This activity continues until the condition of outer while loop becomes false
