写出输出整数数组的宏定义，要求数组元素个数和一行输出多少个整数作为宏的形参，怎么写啊

Answer 1

#include <stdio.h>
#define PNT(LEN,LINE) for(i=0;i<LEN;i++){printf("%5d",a[i]);if(i%LINE==LINE-1){printf("\n");}}
int main()
{
int a[17] = {1,22,3,4,15,6,7,58,9,0,23,49,16,30,95,107,73};
int i;
PNT(17,3)
printf("\n\n");
PNT(17,5)
return 0;
}

Answer 2

#include<stdio.h>
#define s(a,n) for (i=0;i<n;i++) printf("%d ",a[i])
void main()
{int c[10]={1,2,4,5,9,8,7,3,6,10},i;
s(c,10);}
我试过，基本可行...

Answer 3

供参考吧:

#include<stdio.h>

#define PrintArray(a, n)\
do\
{\
int i = 0;\
for(i =0; i < sizeof(a)/sizeof(int); i++)\
{\
if((i %n == 0) && (i != 0))\
{\
printf("\n");\
}\
printf("%d ",a[i]);\
}\
printf("\n");\
}while(0)

void main()
{
int a[10]={1,3,4,2,5,1,2,4,7,4};

PrintArray(a,2);

}
