X—X help please. Increment X by one

Question

for (int i = 1; i <= 2; i++)
{
x = X+1;
break;
}

I want increment x by 2

Answer 1

Why are you breaking a for loop? Also change ‘X’ to ‘x’ for the x = X+1; part. Also tab that part.

Here’s a better way to do that (if you need a loop to do this):

// Initialize variable x (if needed)
int x = 0;

// Loop that runs twice (i = 0, i = 1)
for (int i = 0; i < 2; ++i) {
// Increment x by 1 in each iteration
++x;
}

If you don’t need a loop do this:

// Initialize variable x (if needed)
int x = 0;

// Increment x by 2 directly (equivalent to the loop)
x += 2;

Also pre-increment (++x) can be more efficient than post-increment (x++) because it avoids the overhead of creating a temporary copy of the variable. Which is why I’m doing that if you’re curious, but some people hate that and prefer i++/x++ and for modern compilers the difference is minimal.
