C program for print solid rectangle and square star pattern

C program for print 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

Program 1

C program for Display rectangle or square  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

 

#include <stdio.h>
#include <stdlib.h>

int main()
{
    int rows,columns,i,j;
    printf("Enter the number of rows: ");
    scanf("%d",&rows);
    //Takes input from user for rows
    printf("Enter the number of columns: ");
    scanf("%d",&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
        printf("*");//print star
    }
    printf("\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 <stdio.h>
#include <stdlib.h>

int main()
{
    int rows,columns,i,j;
    printf("Enter the number of rows: ");
    scanf("%d",&rows);
    //Takes input from user for rows
    printf("Enter the number of columns: ");
    scanf("%d",&columns);
     //Takes input from user for columns
     i=1;
     while( i<=rows){//outer while loop
            j=1;
    while(j<=columns){//inner while loop
        printf("*");//print star
        j++;
    }
    printf("\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 and square patterns using the do-while loop in C programming language

#include <stdio.h>
#include <stdlib.h>

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

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