Question

I have this programming problem, I’m using C#. I want to check if varA is less than 8 then execute the code which decreases the value, like this

//intial
float varA = 0.0f;

if(varA <= 8.0f){

varA -= 2.0f;

}

This code works fine, but the problem is that if varA is less than 8 then I want it to increase up it to 8 first then start decreasing.

For instance, if the varA equals 6 then it should be increased to 8 and then start decreasing. Hopefully you have got what I mean. Thanks.

Answer 1

You need a flag to tell you when to start running your subtraction code.

Boolean doIt = false;

// your outer loop
{
  if (varA ==8.0f) {
    doIt = true;
  }

  if ((doIt) && (varA <= 8.0f)) {
    varA -= 2.0f;
  }
}

of course, the main problem above is what happens if varA is 9.0. In this case, it will not decrease but that may or may not matter to you.
