- c语言结构体中指针数组怎样赋值
- 定义一个结构体
struct AS
{
char *p[1];
};
怎样用gets函数给指针数组赋值呢?
解决方案
看Unix/Linux上的man:
Standard C Library Functions gets(3C)
NAME
gets fgets - get a string from a stream
SYNOPSIS
#include
char *gets(char *s); char *fgets(char *s int n FILE *stream);
DESCRIPTION
The gets() function reads bytes from the standard input
stream (see intro(3)) stdin into the array pointed to by
s until a newline character is read or an end-of-file con-
dition is encountered. The newline character is discarded
and the string is terminated with a null byte.
....
gets是标准库函数,要求传入的是一个数组的地址。其实是要求caller应当分配空间给他。你的结构体中指针数组指向了已经分配好的内存吗?如果没有就别想了。想用就自己先给他空间
