Please correct my code to print 2*4**6*** (within separate lines)

Question

#include <iostream>
using namespace std;
int main()
{
int x=2;
int y=1;
while (x<7)
{
cout<<x;
while (y<4)
{
cout<<"*";
if (y==x/2)
break;
y++;
}
x+=2;
cout<<endl;
}
return 0;
}

Answer 1

@Nasma Najeeb The problem was that you forgotten to re-initialize y to zero for the outer loop. This causes y to keep incrementing and reach the designated limit earlier than expected.

Answer 2

// A few tweaks from your code. Remember to indent code for readability next time.

#include <iostream>
using namespace std;

int main()
{
int x=2, y;
while (x<7)
{
y=0;
cout<<x;
while (y< x/2)
{
cout<<"*";
y++;
}
x+=2;
cout<<endl;
}
return 0;
}

Answer 3

You can really just do:

for (int i = 2; i <= 6; i += 2)
{
cout << i;
for (int j = 0; j < i/2; j++)
cout << "*";
cout << endl;
}

Answer 4

K just give me a few minutes.

Thank you very much, BTW can you mention my mistake??

The mistake is that you did not reinitialise y value each loop
