C++ program for solid rectangle and square star pattern

In this article, we will discuss the concept of C++ program for Display the solid rectangle or square star pattern.

In this post, we are going to learn how to write a program to print solid rectangle or square star pattern in C++ programming language using for loop, while loop and Do-while loop with example programs

C++ program for rectangle or square star pattern

Print solid rectangle using for loop

This program allows the user to enter the number of rows and columns and then it will display the solid rectangle or square pattern using for loop in C++ programming language

Program 1

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

int main()
{
    int rows,columns,i,j;
    cout<<"Enter the number of rows: ";
    cin>>rows;
    //Takes input from user for rows
    cout<<"Enter the number of columns: ";
    cin>>columns;
     //Takes input from user for columns
     for(i=1; i<=rows; i++){//outer for loop
    for (j=1; j<=columns; j++){//inner for loop
        cout<<"*";//print star
    }
    cout<<"\n";//move to next line
}
getch();
    return 0;
}

When the above code is executed, it produces the following results

Program 2

Print solid rectangle using while loop

This program allows the user to enter the number of rows and columns and then it will display the solid rectangle or square pattern using while loop in C++ programming language

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

int main()
{
    int rows,columns,i,j;
    cout<<"Enter the number of rows: ";
    cin>>rows;
    //Takes input from user for rows
    cout<<"Enter the number of columns: ";
    cin>>columns;
     //Takes input from user for columns
     i=1;
     while( i<=rows){//outer while loop
            j=1;
    while(j<=columns){//inner while loop
        cout<<"*";//print star
        j++;
    }
    cout<<"\n";//move to next line
     i++;
}
getch();
    return 0;
}

When the above code is executed, it produces the following results

Program 3

Print solid rectangle using the do-while loop

This program allows the user to enter the number of rows and columns and then it will display the solid rectangle or square pattern using the do-while loop in C++ programming language

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

int main()
{
    int rows,columns,i,j;
    cout<<"Enter the number of rows: ";
    cin>>rows;
    //Takes input from user for rows
    cout<<"Enter the number of columns: ";
    cin>>columns;
     //Takes input from user for columns
     i=1;
    do{
            j=1;
    do{
        cout<<"*";//print star
        j++;
    }while(j<=columns);
    cout<<"\n";//move to next line
     i++;
} while( i<=rows);
getch();
    return 0;
}

When the above code is executed, it produces the following results
