Explain the difference between 1 and 2 and give the value for x in both when x is 1.

1)

if ( x >= 0)

x = x + 1;

else if ( x >= 1)

x = x + 2;

2)

if ( x >= 0)

x = x + 1;

if ( x >= 1)

x = x + 2;

I came up with they're are both the same and x simply would be 3 for both of them. Im almost sure I am wrong however I feel like i don't fully understand the entire concept of why, can anyone give me the x value for both and explain how they are different ( minus the obvious that one says else).
