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 Program to print solid square star 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 <stdio.h>
#include <stdlib.h>

int main()
{
    int i,j,size;
    printf("Please enter the size\n");
    scanf("%d",&size); //get input from the user for size
    for (i=1; i<=size; i++){
  for (j=1; j<=size; j++){
  printf("*");
  }
  printf("\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 Program to print solid square star Using while loop

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

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

int main()
{
    int i,j,size;
    printf("Please enter the size\n");
    scanf("%d",&size); //get input from the user for size
    i=1;
    while(i<=size){
            j=1;
  while(j<=size){
  printf("*");
   j++;
  }
  printf("\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 Program to print solid square star Using the do-while loop

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

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

int main()
{
    int i,j,size;
    printf("Please enter the size\n");
    scanf("%d",&size); //get input from the user for size
    i=1;
    do{
            j=1;
do{
  printf("*");
   j++;
  }while(j<=size);
  printf("\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
