需要在堆栈上推送弹出字符串 [英] need to push pop strings on a stack
问题描述
我需要一些C建议我想用来自用户的字符串命令读取
当用户输入一个\ n
我想把它推到stac上。然后在某些时候，如果用户输入
，则弹出单词print并打印每个单词（或使用另一个堆栈
指针扫描堆栈打印每个字符串）。这是我想要做的事情的存根。 （我如何实现这个目前我的代码不起作用
由于我缺少字符串和指针）
#include< stdio.h>
#include< ctype.h>
#define CMDBUFFER 10
char iItem [10]，* x;
int iSp;
void push（char *）;
char pop（void）;
void main （）
{
int iCur，iCharCount = 0，i1，i2，bExit = 0;
char * cPos， * cTok1 = NULL，* cTok2 = NULL，* cTok3 = NULL;
char cVal，cSwitch;
char cString [CMDBUFFER] =" " ;;
enum eTokens {Exit = 0，Add = 1，Subtract = 2，Multiply = 3，Divide = 4};
while（bExit == 0）
{
cString [CMDBUFFER] =" " ;;
printf（"："）;
cVal = getchar（）;
while（cVal！=''\\ \\ n''）
{
cString [iCharCount ++] = tolower（cVal）;
cVal = getchar（）;
}
cString [iCharCount ++] =''\ 0'';
iCharCount = 0; // reset cString
push（& cString）;
* x = pop（）;
printf（" main％s \\ \\ n"，x）;
}
}
void push（char * p）
{
iItem [iSp ++] = p;
}
char pop（void）
{
printf（"％i \ n"，iSp）;
char * x = iItem [--iSp];
printf（" pop％s \ n"，x）;
返回* x;
}
I need some C advice I want to read in string commands from a user
when the user enters a \n
I want to push it on the stac. Then at some point , if the user enters
the word print pop off and print each word (or using another stack
pointer scan the stack printing each string). here is a stub of what i
want to do. (how do I implement this currently my code doesn''t work
due to my lack of strings and pointers)
#include <stdio.h>
#include <ctype.h>
#define CMDBUFFER 10
char iItem[10],*x;
int iSp;
void push(char*);
char pop(void) ;
void main()
{
int iCur,iCharCount=0,i1,i2,bExit=0;
char *cPos,*cTok1=NULL,*cTok2=NULL,*cTok3=NULL;
char cVal,cSwitch;
char cString[CMDBUFFER]=" ";
enum eTokens {Exit=0,Add=1,Subtract=2,Multiply=3,Divide=4};
while(bExit==0)
{
cString[CMDBUFFER]=" ";
printf(":");
cVal=getchar();
while(cVal != ''\n'')
{
cString[iCharCount++] = tolower(cVal);
cVal=getchar();
}
cString[iCharCount++] =''\0'';
iCharCount=0; //reset cString
push(&cString);
*x=pop();
printf ("main %s\n",x);
}
}
void push(char *p)
{
iItem [iSp++]=p;
}
char pop(void)
{
printf("%i\n",iSp);
char *x=iItem [--iSp];
printf ("pop %s\n",x);
return *x;
}

嗨Martin，
什么是正确的形式？正如我所提到的，我不熟悉C和
目前正在读一本书
（1984年印刷的格子实验室的C参考，也许是一个坏主意）

Hi Martin ,
What was the correct form? as I mentioned I am unfamiliar with C and
currently reading a book
(The C refrence from tartan labs printed in 1984 , maybe a bad idea)

它有，TTBOMKAB，*从不*是C的一部分。

这取决于。他刚刚出版了一本新书吗？如果我的
问题的答案是是，那么它也可能是你的答案。

That depends. Has he just published a new book? If the answer to my
question is "yes", then it is probably the answer to yours, too.
