Oct 28, 2009 · At least because such constants are typed and scoped. There are simply no reasons to prefer #define over const, aside from few exceptions. String constants, BTW, are one example of such an exception. With #defined string constants one can use compile-time concatenation feature of C/C++ compilers, as in
Dec 22, 2009 · The use of an enumeration constant (enum) has many advantages over using the traditional symbolic constant style of #define. These advantages include a lower maintenance requirement, improved program readability, and better debugging capability.
Jun 8, 2011 · #define MY_MACRO printf( \ "I like %d types of cheese\n", \ 5 \ ) But you cannot do that with your first example. You cannot split tokens like that; the << left-shift operator must always be written without any separating whitespace, otherwise it would be interpreted as two less-than operators.
#define creates an entity for substitution by the macro pre-processor, which is quite different from a constant because depending on what you define it will or will not be treated as a constant. The contents of a #define can be arbitrarily complex, the classic example is like this: #define SQR(x) (x)*(x) Then later if used: SQR(2+3*4)
Feb 12, 2021 · Statements defined using #define are called macros. And macros are used in a multitude of uses. We can use them to conditionally compile sections of code. #ifdef ONE int AddOne(int x) { return x + 1; } #else int AddTwo(int x) { return x + 2; } #endif When we don't need to store constants in a variable. #define MAX_BOUND 1000 #define MIN_BOUND 10
Mar 4, 2017 · In many programs a #define serves the same purpose as a constant. For example. #define FIELD_WIDTH 10 const int fieldWidth = 10; I commonly see the first form preferred over the other, relying on the pre-processor to handle what is basically an application decision. Is there a reason for this tradition?
Jul 26, 2015 · Constants should be preferred over defines. There are several advantages: Type safety. While C is a weakly typed languaged, using a define loses all of the type safety, which will allow the compiler to pick up problems for you. Ease of debugging.
Jun 29, 2010 · enum offers you scoping and automatic value assignment, but does not give any control over the constant type (always signed int). #define ignores scoping, but allows you to use better typing facilities: lets you choose the constant type (either by using suffixes or by including an explicit cast into the definition).
Nov 4, 2009 · Incidentally, an alternative to #define, which provides proper scoping but behaves like a "real" constant, is "enum". For example: enum {number_ten = 10}; In many cases, it's useful to define enumerated types and create variables of those types; if that is done, debuggers may be able to display variables according to their enumeration name.
Feb 15, 2017 · I was wondering how I could define a really long string over the multiple lines. I tried so many different patterns, but none of them is working.. Here is my code. #define EXAMPLE "
