动态增长数组的实现

动态增长数组的实现：
完整代码如下：


#include <stdio.h>
#include <stdlib.h>
#include <stdint.h>
//Dynamically growing array to save ip address
unsigned int current_element = -1;
unsigned int total_element = 10;
uint32_t* dynamic;
uint32_t* ptr;

int main()
{
	dynamic = (uint32_t*)malloc(sizeof(uint32_t) * total_element);

	for (int i = 0; i < 100; i++) {
		if (current_element >= total_element - 1) {
			total_element *= 2;
			ptr = (uint32_t*)realloc(dynamic, sizeof(uint32_t) * total_element);
			if (ptr == NULL) {
				printf("Can't expand the table!!!\n");
				return;
			}
			else {

				dynamic = ptr;
			}
		}
		current_element++;
	    dynamic[current_element] = i;

	}

	for (int i = 0; i < 100; i++) {
		printf("%d  ", dynamic[i]);
	}

	free(dynamic);
	return 0;
}
