1.读下面的程序#include<stdio.h>#include<stdlib.h>#include<string.h>void GetMemory(char *p){ p = (char *)malloc(100);}void Test(void){ char *str = NULL; GetMemory(str); strcpy(str, "hello world"); printf(str);}int main(){ Test

1.调整数组使得奇数全部位于偶数前面#include<stdio.h>void move(int arr[], int sz){ int i = 0; int left = 0; int right = sz - 1; while (left < right) { while (arr[left] % 2 != 0 && left < right) { left++; break; } while (arr[right

1.用指针数组模拟打印二维数组#include<stdio.h>#include<stdlib.h>int main(){ int a1[] = { 1,2,3,4,5 }; int a2[] = { 2,3,4,5,6 }; int a3[] = { 6,3,4,5,7 }; int* parr[3] = { a1, a2, a3 }; for (int i = 0; i < 3; i++) { for (int j = 0; j < 5;
