[Help] When you are programming, does the program run faster Updates to this post /post/217733-when-you-are-programming-does-the Sun, 29 Nov 2009 19:39:04 +0100 Reply from Ed23454 /post/217733-when-you-are-programming-does-the#reply-4490193 [quote spiratec9]it won’t make any difference because the compiler will substitute

Only if the variable is defined as constant. If it is a changing variable than it couldn’t be replaced by the compiler, it would be constant than.

Marcos & Constants can be used to make the compiler subsitute, however vairables, are variant.

In C++, (I just looked ‘em up in my C++ Book =D)
they are written

#define var3 37474.343475

so whenever you type var3 it really means 37474.336….

It is prabely simular in those languages

than when you type out x2 the compiler changes it to the number.

Java and other languages might have them too…. what language is it in?

You write with the other global declarations:

#define x2 = 2743345734.34538

somthing like that….I don’t think the format is right…
But thats only good for C++ anyway.

Wright /post/217733-when-you-are-programming-does-the#reply-4489996 Somewhere in the future I am planning on writing a large program, and every bit of speed will matter. Right now I will use the variable because it is a long constant and just a small program.

This is becuse it dosn’t have to acess the programs alloacted space for random memory storage and withdrawl the variable. Either way, it only makes less than a millisecond diference. It is impossiable to see, in simple programs anyway.

But you can’t really go by me, becuse I am just a beginner programmer in C++, .NET, and Java.
