Question

IN C++

Write a program using for loops to produce the following output. Please read carefully the entire specification! Your program must work for any odd number entered by the user, not just 13. (NOTE that there is no space after the colon on the Hill, Triangle, and Diamond labels.) Enter an odd number width: 13 Hill: Triangle no spaces Diamond

Answer 1

Here is code:

// C++ code to demonstrate star pattern

#include <iostream>

#include <limits>

using namespace std;

void triangle(int n)

{

for (int i = 0; i <= n / 2; i++)

{

int j = 0;

// space

for (j = 0; j < n / 2 - i; j++)

cout << " ";

for (int k = 0; k <= 2 * i; k++)

{

cout << "*";

j++;

}

cout << endl;

}

}

void diamond(int n)

{

int c, k, space = 1;

space = n / 2;

for (k = 1; k <= n / 2 + 1; k++)

{

for (c = 1; c <= space; c++)

cout << " ";

space--;

for (c = 1; c <= 2 * k - 1; c++)

cout << "*";

cout << "\n";

}

space = 1;

for (k = n / 2; k < n; k++)

{

for (c = 0; c < space; c++)

cout << " ";

space++;

for (c = 1; c <= 2 * (n - k) - 3; c++)

cout << "*";

cout << "\n";

}

}

void hill(int n)

{

for (int i = 0; i < n / 2 + 1; i++)

{

for (int j = 0; j <= i; j++)

{

cout << "*";

}

cout << endl;

}

}

int main()

{

int num;

cout << "Enter positive odd number : ";

while (!(cin >> num) || (num < 0 || num % 2 == 0))

{

// flush the cin data

cin.clear();

cin.ignore(numeric_limits<streamsize>::max(), '\n');

cout << "Invalid entry, Try again : ";

}

cout << "Hill:" << endl;

hill(num);

cout << "Triangle:" << endl;

triangle(num);

cout << "Diamond:" << endl;

diamond(num);

return 0;

}

Output:

null
