一、程序C语言代码展示如下：

/************************************************
运行平台：vc++6.0
实现功能：体现realloc函数的作用
************************************************/
#include
#include

#define NUM1 5
#define NUM2 10

int main(void)
{
int i = 0;
int *point = (int *)malloc(NUM1*sizeof(int));

printf("malloc指针point的值为：%p\n", point);

printf("为point[%d]~point[%d]赋值：\n", 0, NUM1-1);
for(i=0; i {
scanf("%d", &point[i]);
}
printf("point[%d]~point[%d]的值为：\n", 0, NUM1-1);
for(i=0; i {
printf("%2d", point[i]);
}
printf("\n\n");

point=(int *)realloc(point, NUM2*sizeof(int));
printf("realloc指针point的值为：%p\n", point);

printf("为point[%d]~point[%d]赋值：\n", NUM1, NUM2-1);
for(i=NUM1; i {
scanf("%d", &point[i]);
}

printf("point[%d]~point[%d]的值为：\n", 0, NUM2-1);
for(i=0; i {
printf("%2d", point[i]);
}
printf("\n");

free(point);

return 0;
}

将C语言梳理一下，分布在以下10个章节中：
