1. #DEFINE 응용 - HAP(CAKE)
Q : x+y, x*y 로 각각 정의하고, h1, h2 를 10과 곱하여 출력하라
x = 3, y = 4
A :
#include <stdio.h>
#define CAKE1(x,y) x+y
#define CAKE2(x,y) (x+y)
int main () {
int h1 = 0, h2 = 0 ;
h1 = 10 * CAKE1(3,4) ; h2 = 10 * CAKE2(3,4) ;
printf("h1 = %d , h2 = %d ", h1, h2);
return 0;
}
h1 = 34, h2 = 70
==============================================
2. define, output, count 응용
Q : output() 을 x로 정의하고, count 를 활용해 3X3 로 나오게 출력하라
A : #include <stdio.h>
#define output(x) printf("%d %d %d/n" , x##1, x##2, x##3)
int main () {
int count1=0, count2=0, count3=0, i1=0, i2=0, i3=0 ;
count 1 = 1 ; count 2 = 4; count 3 = 5 ;
i1 = 2 ; i2 = 3, i3 = 6
output(count) ;
output(i) ;
return 0;
}
