1有如下c语言程序，其中的H和J定义为一个常数。#include "stdio.h"#define H ? //定义常数H#define J ? //定义常数Jint array1[H][J];int array2[J][H];void f(int x, int y){ array1[x][y] = x + 2 * y; array2[y][x] = y - x * x;}int main(){ return 0;}在Ubuntu 32位系统下经过g

题目选题三对于以下c程序：#include <stdio.h> int main() { int i=0; int j=0; switch(i) { case 1: j+=1; break; case 2: j+=2; break; case 3: j+=3; break; case 4:
