Program to Print Hollow Square Star Pattern in C, C++, and Python
Below are the ways to print the hollow square star pattern in C, C++, and Python.
Method #1: Using For loop (Star Character)
Approach:
- Give the side of the square as static input and store it in a variable.
- Loop till the side length of the square using For loop.
- Loop till the side length of the square using another nested For loop.
- We use the If Else statement to check If the side length is 0 or maximum – 1.
- If it is true then print * else print space.
- The Exit of the Program.
1) Python Implementation
Below is the implementation:
# Give the side of the square as static input and store it in a variable. squareside = 6 # Loop till the side length of the square using For loop. for m in range(squareside): # Loop till the side length of the square using another nested For loop. for n in range(squareside): # We use the If Else statement to check If the length or breadth number is 0 or maximum – 1. # If it is true then print * else print space. if(m == 0 or m == squareside - 1 or n == 0 or n == squareside - 1): print('*', end=' ') else: print(' ', end=' ') print()
Output:
* * * * * * * * * * * * * * * * * * * *
2) C++Implementation
Below is the implementation:
#include <iostream> using namespace std; int main() { // Give the side of the square as static input and store // it in a variable. int squareside = 19; // Loop till the side length of the square using For // loop. for (int m = 0; m < squareside; m++) { // Loop till the side length of the square using // another nested For loop. for (int n = 0; n < squareside; n++) { // We use the If Else statement to check If the // side length is 0 or maximum – 1. if (m == 0 || m == squareside - 1 || n == 0 || n == squareside - 1) cout << "* "; else cout << " "; } cout << endl; } return 0; }
Output:
* * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * *
3) C Implementation
Below is the implementation:
#include <stdio.h> int main() { // Give the side of the square as static input and store // it in a variable. int squareside = 5; // Loop till the side length of the square using For // loop. for (int m = 0; m < squareside; m++) { // Loop till the side length of the square using // another nested For loop. for (int n = 0; n < squareside; n++) { // We use the If Else statement to check If the // side length is 0 or maximum – 1. if (m == 0 || m == squareside - 1 || n == 0 || n == squareside - 1) printf("* "); else printf(" "); } printf("\n"); } }
Output:
* * * * * * * * * * * * * * * *
Method #2: Using For Loop (User Character)
Approach:
- Give the side of the square as user input and store it in a variable.
- Scan the character to print as user input and store it in a variable.
- Loop till the side length of the square using For loop.
- Loop till the side length of the square using another nested For loop.
- We use the If Else statement to check If the side length is 0 or maximum – 1.
- If it is true then print the given character else print space.
- The Exit of the Program.
1) Python Implementation
- Give the number of sides of the square as user input using int(input()) and store it in a variable.
- Give the Character as user input using input() and store it in another variable.
Below is the implementation:
# Give the side of the square as user input and store it in a variable. squareside = int(input('Enter some random number of sides of square = ')) # Scan the character to print as user input and store it in a variable. characte = input('Enter some random character to print = ') # Loop till the side length of the square using For loop. for m in range(squareside): # Loop till the side length of the square using another nested For loop. for n in range(squareside): # We use the If Else statement to check If the length or breadth number is 0 or maximum – 1. # If it is true then print the given character else print space. if(m == 0 or m == squareside - 1 or n == 0 or n == squareside - 1): print(characte, end=' ') else: print(' ', end=' ') print()
Output:
Enter some random number of sides of square = 7 Enter some random character to print = ( ( ( ( ( ( ( ( (Â Â Â Â Â Â ( (Â Â Â Â Â Â ( (Â Â Â Â Â Â ( (Â Â Â Â Â Â ( (Â Â Â Â Â Â ( ( ( ( ( ( ( (
2) C++Implementation
- Give the number of sides of the square as user input using cin and store it in a variable.
- Create a character variable.
- Give the character as user input using cin and store it in another variable.
Below is the implementation:
#include <iostream> using namespace std; int main(void) { int sidesnum; char characte; // Give the number of sides of the square as user input // using cin and // store it in a variable. cout << "Enter some random number of sides of the " "square = " << endl; cin >> sidesnum; // Create a character variable. // Give the character as user input using cin and store // it in another variable. cout << "Enter some random character to print = " << endl; cin >> characte; cout << endl; // Using Nested For loops print the square pattern. for (int m = 0; m < sidesnum; m++) { for (int n = 0; n < sidesnum; n++) { // We use the If Else statement to check If the // length or breadth number is 0 or maximum – 1. // If it is true then print the given character // else print space. if (m == 0 || m == sidesnum - 1 || n == 0 || n == sidesnum - 1) cout << characte << " "; else cout << " "; } cout << endl; } return 0; }
Output:
Enter some random number of sides of the square = 8 Enter some random character to print = + + + + + + + + + +Â Â Â Â Â Â Â Â Â Â Â + +Â Â Â Â Â Â Â Â Â Â Â + +Â Â Â Â Â Â Â Â Â Â Â + +Â Â Â Â Â Â Â Â Â Â Â + +Â Â Â Â Â Â Â Â Â Â Â + +Â Â Â Â Â Â Â Â Â Â Â + + + + + + + + +
3) C Implementation
- Give the number of sides of the square as user input using scanf and store it in a variable.
- Create a character variable.
- Give the character as user input using scanf and store it in another variable.
Below is the implementation:
#include <stdio.h> int main() { int sidesnum; char characte; // Give the number of sides of the square as user input // using scanf and // store it in a variable. // Create a character variable. // Give the character as user input using scanf and // store it in another variable. // Using Nested For loops print the square pattern. scanf("%d%c", &sidesnum, &characte); printf("\n"); for (int m = 0; m < sidesnum; m++) { for (int n = 0; n < sidesnum; n++) { // We use the If Else statement to check If the // length or breadth number is 0 or maximum – 1. // If it is true then print the given character // else print space. if (m == 0 || m == sidesnum - 1 || n == 0 || n == sidesnum - 1) printf("%c ", characte); else printf(" "); } printf("\n"); } }
Output:
8^ ^ ^ ^ ^ ^ ^ ^ ^ ^Â Â Â Â Â Â Â Â Â Â Â ^ ^Â Â Â Â Â Â Â Â Â Â Â ^ ^Â Â Â Â Â Â Â Â Â Â Â ^ ^Â Â Â Â Â Â Â Â Â Â Â ^ ^Â Â Â Â Â Â Â Â Â Â Â ^ ^Â Â Â Â Â Â Â Â Â Â Â ^ ^ ^ ^ ^ ^ ^ ^ ^
