请告诉程序输出 [英] please tell the output of the program

问题描述

#include
main()
{
char *q;
int *ip;
q=(char*)malloc(100);
ip=(int*)q;
free(ip);
}

推荐答案

结果"没有显示在屏幕上. (我假设#include指向stdio.h，否则结果是一堆编译器错误)

运行后，您将分配100个字符的内存.然后，将指向该内存块的指针复制到(a)* q和(b)* ip.

您可以释放分配的内存并退出程序.


我应该提到需要将main声明为返回一个int(除非您使用的是恐龙走过地球时的编译器)

The ''result'' is nothing displayed on screen. (I''ll assume that #include refers to stdio.h, otherwise the result is a bunch of compiler errors)

Once running, you allocate memory for 100 chars. You then copy a pointer to this memory block into (a) *q and (b) *ip.

You free the memory you allocated and exit program.


I should mention the need to declare main as returning an int (unless you''re using a compiler that was around when dinosaurs walked the earth)
