simple c++ loop question

[MisterWhite]

So i have this exercise:

Write a C++ program to ask the user for his/her name and a size, and display a hollow rectangle with it:

Enter your name: Yo
Enter height: 4

Enter width:4
YoYoYoYo
Yo____Yo
Yo____Yo
YoYoYoYo
(note: the underscores _ should not be displayed on screen; you program should display blank spaces inside the rectangle)

 

And i can't come up with the solution for this, any help?

Is your question about the underscores being changed to blanks or the programm as a whole?

Oh, and don't forget to follow your own topics.

Just how to make those 2 loops (i think there should be 2), so that there would be "spaces" in the middle

[Sauron]

in pseudocode (won't write it for you )

print "enter your name"input -> nameprint "enter height"input -> heightprint "enter width"input -> widthfor(i from 0 to (width-1))   print name;print "\n"for(i from 0 to (height-3))   print name + (width-2)*" " + name + "\n"for(i from 0 to (width-1))   print name;print "\n"

print "enter your name"input -> nameprint "enter height"input -> heightprint "enter width"input -> widthfor(i from 0 to (width-1))   print name;print "\n"for(i from 0 to (height-3))   print name + (width-2)*" " + name + "\n"for(i from 0 to (width-1))   print name;print "\n"

What will happen when you do this  ' (width-2)*" "  '  i mean multiply a number by space?

it means, print (width-2) spaces

[MisterWhite]

it means, print (width-2) spaces

It doesn't work that way . error

[Sauron]

It doesn't work that way . error

 

because it's pseudocode, you need to figure out how to express it in c++

[MisterWhite]

Just out of curiosity, you know how to do it?

[Sauron]

Just out of curiosity, you know how to do it?

 

Of course

 

-edit-

 

by the way if you want you can nest another for loop to print the spaces

for(i from 0 to (height-3))   print name   for(a from 0 to (width-3))      print " "   print name   print "\n"

Shall I just give you the whole code? But that way I'm not really doing you a favor.

If i will fail, i will "summon" you

#include <iostream>

#include <string>

int main(int argc, const char * argv[]) {

std::string name;

int height, width;

std::cout << "Name: ";

std::cin >> name;

std::cout << "Height: ";

std::cin >> height;

std::cout << "widht: ";

std::cin >> width;

std::string space((name.length()*width) - (name.length()*2), ' ');

std::string midRows = name + space + name;

for(int w = 0; w < width; w++)

std::cout << name;

std::cout << std::endl;

for(int h = 0; h < (height - 2); h++)

std::cout << midRows << std::endl;

for(int w = 0; w < width; w++)

std::cout << name;

return 0;

}

HEYYYY i did it , wanna see the code?

[Sauron]

sure - did I help?

[MisterWhite]

sure - did I help?

Yes. i just googled how to print a specific amount of spaces and it was just a simple loop of "couts"

Well this is in c# , not c++; but i think you should get the idea:

 

using System;

public class Rectangle

{

    public static void Main()

    {

        string n;

        int width, height;  

        Console.Write ("Enter a word: ");

        n =  (Console.ReadLine());

        Console.Write ("Enter width: ");

        width = Convert.ToInt32 (Console.ReadLine());

        Console.Write ("Enter heigth: ");

        height = Convert.ToInt32 (Console.ReadLine());

        int many = n.Length * (width-2);

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

        {

            Console.Write (n);

        }

        Console.WriteLine ();

        for (int i = 0; i < height-2 ; i++)

        {

            Console.Write (n);

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

            {

                Console.Write (" ");

            }

            Console.Write (n);

            Console.WriteLine ();

        }

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

        {

            Console.Write (n);

        }

        Console.ReadKey ();

    }

}

yeah, that's what this was

 

for(i from 0 to (height-3))   print name   for(a from 0 to (width-3))      print " "   print name   print "\n"
