Print Hollow rectangle and square star pattern in C
Print Hollow rectangle and square star pattern in C
In this article, we will discuss the concept of Program to Print Hollow rectangle or square star patternin C programming language
In this post, we are going to learn How to write a C program to print Hollow rectangle or square star pattern using for loop, while loop and Do-while loop with example programs
Hollow pattern
Program 1
Print Hollow rectangle or square star pattern
Using for loop
This program allows the user to enter the number of rows and columns and then it will display Hollow rectangle and square pattern using for loop in C programming language
#include
#include
int main()
{
int rows,columns,i,j;
printf("Enter the number of rows\n");
scanf("%d",&rows);
printf("Enter the number of columns\n");
scanf("%d",&columns);
for (i=1; i
When the above code is executed, it produces the following results
OutputHollow rectangle and square star pattern
Program 2
Using while loop
This program allows the user to enter the number of rows and columns and then it will display Hollow rectangle and square pattern using while loop in C language
#include
#include
int main()
{
int rows,columns,i,j;
printf("Enter the number of rows\n");
scanf("%d",&rows);
printf("Enter the number of columns\n");
scanf("%d",&columns);
i=1;
while(i
When the above code is executed, it produces the following results
OutputHollow rectangle and square star pattern
Program 3
Using the do-while loop
This program allows the user to enter the number of rows and columns and then it will display Hollow rectangle and square pattern using the do-while loop in C language
#include
#include
int main()
{
int rows,columns,i,j;
printf("Enter the number of rows\n");
scanf("%d",&rows);
printf("Enter the number of columns\n");
scanf("%d",&columns);
i=1;
do{
j=1;
do{
if(i==1||i==rows||j==1||j==columns){
printf("*");
}else{
printf(" ");
}
j++;
}while(j
When the above code is executed, it produces the following results
Hello, Thank you for helping people! I well understood how printing a rectangle with stars. Now, can help about a mixed characters within a rectangle, namely : the first character must be a star (‘*’) at (0,0) and next for each step of d called density ‘*’ or the character ‘.’ either. Input data are : width, height and the density d (each d characters * is printed)* E.g.: for w=5, h= 5 and =2 *.*.* .*.*. *.*.* .*.*. *.*.*

Hello,
Thank you for helping people!
I well understood how printing a rectangle with stars.
Now, can help about a mixed characters within a rectangle, namely : the first character must be a star (‘*’) at (0,0) and next for each step of d called density ‘*’ or the character ‘.’ either.
Input data are : width, height and the density d (each d characters * is printed)*
E.g.: for w=5, h= 5 and =2
*.*.*
.*.*.
