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 = ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( ( (
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 = + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
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^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^ ^
