# define s * x (x) x
Int main ()
{
Int a, b, c;
Int m, n;
A=10;
B=6;
C=3;
Printf (" % d ", s (a - b - c));
}
The output of this program and reason, thank you,

Macro definition is simply to replace, so s (a - b - c) is equal to 10-10-6-6-3 * 3=- 35CodePudding user response:

To define the s of good, know the result is how much and why is this,S (a - b - c)=====a - b - c * a - b - c
Because a - b - c is x, equivalent substitution,
