下面程序的输出结果是()。#define SQR(X)X*Xmain(){ inta=16,k=2,m=11; a/=SQR(k+m)/SQR(k+m); printf("%d\n",a); }

A. 16
B. 2
C. 9
D. 1

用带参数宏多项式4* x*x+3*x+2,最正确的宏定义是()。

A.
B. definef(x) 4*x*x+3*x+2
C. B.
D. definef 4*x*x+3*x+2
E. C.
F. define f(a) (4*(a)*(a)+3*(a)+2)
G. D.
H. define 4*a*a+3*a+2f(a)

对于以下程序段,正确的判断是()。#defineA3#defineB(a) ((A+1)*a)x=3*(A+B(7))

A. 程序错误
B. x=93
C. x=21
D. 宏定义不允许有参数

有下面的程序,执行语句后sum的结果是()。#defineADD(x) x+xsum=ADD(1+2)*3

A. 9
B. 10
C. 12
D. 18

下面程序的执行结果是()。#define MAX(x,y) (x)>(y)?(x):(y)main(){int a=1,b=2,c=3,d=2,t;t=MAX(a+b,c+d)*100;printf("%d\n",t);}

A. 500
B. 5
C. 3
D. 300

设有以下宏定义:#defineA20#defineBA+30则执行赋值语句v=B*2;后,假设v为整型,则v的值为

设有如下宏定义:#define MYSWAP(z,x,y) {z=x;x=y;y=z;),以下程序段通过宏调用实现变量a、b内容交换,请填空.f1oata=5,b=16,c;MYSWAP( ____,a,b);

写出结果#defineSSSV(s1,s2,s3,v)s1=l*w;s2=l*h;s3=w*h;v=w*l*h;main(){int1=3,w=4,h=5,sa,sb,sc,vv;SSSV(sa,sb,sc,vv);printf("sa=%d\nsb=%d\nsc=%d\nvv=%d\n",sa,sb,sc,vv);}

写出结果#include#defineBOT (-2)#defineTOP (BOT+5)#definePRI(arg)printf("%d\n",arg)#defineFOR(arg)for(;(arg);(arg)--)main(){inti=BOT,j=TOP;FOR(j)switch(j){case1:PRI(i++);case2:PRI(j);break;default:PRI(i);}}

写出显示结果#defineNUMokmain(){structstu{intnum;char*name;charsex;floatscore;}*ps;ps=(structstu*)malloc(sizeof(structstu));ps->num=102;ps->name="Zhangping";ps->sex="M';ps->score=62.5;#ifdefNUMprintf("Number=%d\nScore=%f\n",ps->num,ps->score);#elseprintf("Name=%s\nSex=%c\n",ps->name,ps->sex);#endiffree(ps);}
