Question

Using C++ : What am I doing wrong!?!?

Problem Instructions: Implement a program that repeatedly outputs an I of a size entered by the user. Prompt the user for a size. If -1 is entered, quit the program. If an even number or a number smaller than 3 is entered, prompt the user again. Then output a shape of # characters that represent an I. Repeat the program until -1 is entered.

What I have so far:

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

int num;

cout << endl;

cout << " Please enter an ODD number greater than 2: " << endl;

cin >> num;

if (num!= -1)

{

while (num >= 3 && num % 2 == 1)

{

do //Runs if num is invalid

{

if (num %2 == 0)

{

//header

for (int i = 1; i <= num; i++)

{

cout << "#";

}

//middle

for (int i = 1; i <= num; i++)

{

cout << endl;

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

{

cout << " ";

}

cout << "#";

}

cout << endl;

//footer

for (int i = 1; i <= num; i++)

{

cout << "#";

}

}

} while (num >= 3 && num % 2 == 1);

}

}

return 0;

}

If you need any corrections/clarifications kindly comment.

Please give a Thumps Up if you like the answer.

Program

#include <iostream>
#include <iomanip>
using namespace std;
int main()
{
int num;
cout <<"Please enter an ODD number greater than 2: ";
cin >> num;
cout << endl;
while(num!= -1)
{
if ((num %2!= 0)&&(num>2))
{
//header
for (int i = 1; i <= num; i++)
{
cout << "#";
}
//middle
for (int i = 1; i <= num; i++)
{
cout << endl;
for (int i = 1; i <= num / 2; i++)
{
cout << " ";
}
cout << "#";
}
cout << endl;
//footer
for (int i = 1; i <= num; i++)
{
cout << "#";
}
}
cout <<"\nPlease enter an ODD number greater than 2: " ;
cin >> num;
cout << endl;
}
cout <<"Quitting!!!"<<endl;
return 0;
}

Output
