Write programs that will accept an integer input and will display asterisks correspondingly. See examples below:

Program 1:
Enter integer: 5
Output:
* * * * *
* * * * *
* * * * *
* * * * *
* * * * *
//the output is a 5 x 5 set of asterisks

Program 2:
Enter integer: 4
Output:
*
* *
* * *
* * * *
//the output is a triangle-shaped set of asterisks that start with 1 then ends with 4

Program 3:
Enter integer: 5
Output:
* * * * *

Answer 1

Program 1:

#include <iostream>
int main()
{
    int value;
    std::cout << "Enter integer: ";
    std::cin >> value;
  
    for(int i=0; i<value; ++i)
    {
        std::cout << std::string(value, '*') << "\n";
    }

    return 0;
}

Program 2:

#include <iostream>
int main()
{
    int value;
    std::cout << "Enter integer: ";
    std::cin >> value;
  
    for(int i=0; i<value; ++i)
    {
        std::cout << std::string(i + 1, '*') << "\n";
    }

    return 0;
}

Program 3:

#include <iostream>
int main()
{
    int value;
    std::cout << "Enter integer: ";
    std::cin >> value;
  
    for(int i=0; i<value; ++i)
    {
        if(i == 0 || i == (value - 1))
        {
            std::cout << std::string(value, '*') << "\n";
        }
        else
        {
            std::cout << std::string(2, '*') << "\n";
        }
    }

    return 0;
}
