1.Number of lines of diamond should be 2N-1.
For example if user enter 4.
Than the number of lines of diamond should be 7.
2N – 1
2*4 -1
8 – 1
7

And diamond should be like as

This looks like a homework assignment. What do you have so far?

Create a function that outputs a line of '*' given an integer line(int num). Basically 1 would output 1 star, 2 -> 3, 3 -> 5, etc.

Then create a loop from 1 to and including N/2. Then create a loop from N/2 - 1 to and including 1 (these are separate, not nested). In each stage of the loops call call line() with the index of the loop.

You could try doing it recursively too, by creating a version that calls itself, decrementing the number of lines until it reaches zero, then returns:

void line(int n)

{

    if(n == 0)

        return;

    //do your stuff here

    line(n - 1);

}

You'd have to play around with the function calls a little bit though.
