Hello, the line "if(arg2 & 1)" in C++(arg2 is DWORD) is equal to "if(arg2 & 1==0)" in C#(arg2 is Uint32),right? I am trying to translate a function from C++ to C#,but I get an error: Operator '&' cannot be applied to operands of type 'uint' and 'bool' I'd be also thankful if you could see further in the whole function for any other ...
What would be the most readable/best way to write a multiple conditional check such as shown below? Two possibilities that I could think of (this is Java but the language really doesn't matter here): Option 1: boolean c1 = passwordField.getPassword().length > 0; boolean c2 = !stationIDTextField.getText().trim().isEmpty(); boo...
If I have a function with a ton of conditionals what is the best way to organize it? What I am worried about is someone else coming into the code and understanding what is going on. Even though the example is simple imagine that the conditional is very complex. For an example: public void function(string value, string value2) { ...

Consider: if (condition1) { // Code block 1 } else { // Code block 2 } If I know that condition1 will be true the majority of the time, then I should code the logic as written, instead of: if (!condition1) { // Code block 2 } else { // Code block 1 } since I will avoid the penalty of the jump to the second code block ...

I have a file: P 0.5 0.6 0.3 30 300 80 150 160 400 200 150 250 300 T r 45 0 0 s 0.5 1.5 0 0 t 200 –150 . . . When I read in 'P' I know that 3 floats will follow. That will be followed by a finite number of X and Y coordinates. The number will vary until a 'T' is reached which I have to recognize. Then there could be an 'r', 's' or 't...
Hello, I'm writing an image binarization algorithm which simply converts each pixel's luminance value (grayscale image) to a black or white. Currently the algorithm for binarizing each pixel is roughly this if( grayscale[x] < thresholdValue) { bitonal[x] = 1; } (this is actually a simplification of the ACTUAL algorithm because the bit...
I remember many years back, when I was in school, one of my computer science teachers taught us that it was better to check for 'trueness' or 'equality' of a condition and not the negative stuff like 'inequality'. Let me elaborate - If a piece of conditional code can be written by checking whether an expression is true or false, we shou...
Guys I have a couple of questions: Is there a performance difference in Javascript between a switch statement and an if...else if....else? If so why? Is the behavior of switch and if...else if...else different across browsers? (FireFox, IE, Chrome, Opera, Safari) The reason for asking this question is it seems that I get better pe...
