define A(x,y) x*y-x/y main(){int a=5,b=2,y;y=A(a+b,a-b);printf("%d\n",y);}求详解过程

C语言中#define M(X,Y) (X)*(Y)属于什么语法,哪部分知识? 1 执行语句“y= (x = 3,z = --x);”后,变量的值依次为_ .2．设#define a(x) x*x;cout define A(x,y) x*y-x/y main(){int a=5,b=2,y;y=A(a+b,a-b);printf(%d ,y);}求详解过程 #includestdio.h#define sw(x,y) {x^=y;y^=x;x^=y;}main(){int a=10,b=01;sw(a,b);printf(%d,%d ,a, #define max(x,y) x>y?x:其中的表达式 x>y?x:还有,C中哪些时候要用分号结尾（具体点最好了）?
