How to define Max in define in c
To define the maximum value using the #define
directive in C, you can follow the syntax below:
#define MAX(a, b) ((a) > (b) ? (a) : (b))
This macro definition takes two arguments, a
and b
, and it returns the larger of the two values. The macro uses the conditional operator (a) > (b) ? (a) : (b)
to compare the values of a
and b
. If a
is greater than b
, the macro returns a
, otherwise it returns b
.
You can then use the MAX
macro in your code to get the maximum value between two variables, like this:
int x = 5;
int y = 10;
int max_value = MAX(x, y);
In this example, max_value
will be assigned the value of y
(which is 10) because y
is greater than x
.
Note: It's important to wrap the arguments a
and b
in parentheses within the macro definition to avoid unexpected behavior when using the macro.
