Message:
Use for loops
Posted by Hiran on January 25, 2002 at 2:48 PM
Imran, the best way would probably be to use three for loops. One counting upwards and one counting downwards. You would also need a loop outputing the same amount of stars as the input number. Here's some code to help:
//assuming the input is 5
for (int i=1; i<5; i=i+2)
{
for (int j=1; j<(i+1); j++)
{
System.out.print("*");
}
System.out.print('\n');
}
for (int i=1; i<6; i++)
{
System.out.print("*");
}
System.out.print('\n');
for (int i=3; i>0; i=i-2)
{
for (int j=1; j<4; j++)
{
System.out.print("*");
}
System.out.print('\n');
}
Of course, you would need to substitute using variables (instead of the actual values). Also, if '\n' doesn't work, try "\\n", or create a character variable that holds \n (ie, char c = '\n') and output that variable. (By the way, if you don't know, the \n is the symbol for a new line). Hope this helps.
