问题描述
嗨！
现在在string-class一章中我的作业在Word计数器下面：
编写一个函数，接受指向C-String的指针作为参数
并返回字符串中包含的单词数。例如，如果字符串参数是四分和七年前，那么
函数
应返回数字6.在程序中演示函数
要求用户输入字符串然后将其传递给函数。字符串中的
字数
应该显示在屏幕上。它还应该显示
每个字的平均字母数。
这是我的程序的开始
我收到两个错误：LNK2001：未解析的外部符号" char
__cdecl wordCount（char ）" （？wordCount @@ YADD @ Z）
Debug / 1.exe：致命错误LNK1120：1个未解析的外部
------------ -------------------------------------------------- ------------- * -----------------
#include< iostream>

Hi!
now on the chapter "string-class" My assignment is below Word Counter:
Write a function that accepts a pointer to a C-String as an argument
and returns the number of words contained in the string. For instance,
if the string argument is "Four score and seven years ago" the function
should return the number 6. Demonstrate the function in a program that
asks the user to input a string and then passes it to the function. The
number of words
in the string should be displayed on the screen.It should also display
the average number of letters in each word.
Here is the begining of my program
I am getting two errors: LNK2001: unresolved external symbol "char
__cdecl wordCount(char)" (?wordCount@@YADD@Z)
Debug/1.exe : fatal error LNK1120: 1 unresolved externals
---------------------------------------------------------------------------*-----------------
#include <iostream>
#include <string>
#include <iomanip>
#include <ctype.h>
using namespace std;
char wordCount(char );
int main()
{
char cstring[81];
cout << "\nEnter a string, 80 or fewer characters:\n";
cin.getline(cstring, 81);
cout << "\nThe number of words in that string: ";
cout << wordCount(cstring[81]) << endl;
return 0;
}
char wordCount(char cstring[81])
{
int index = 0;
int word = 0;
while (cstring[index] != ''\0'')
{
if (isspace(cstring[index]))
{
while (isspace(cstring[index]))
{
index++;
}
}
if (isalnum(cstring[index]))
{
word++; //we must be in a word
while(islower(cstring[index]))
{
word++;
}
}
index++;
}
return cstring[word];
}
---------------------------------------------------------------------------*
can anyone find the error and perhaps make a suggestion to fix it.

}
这次没有错误，但是当它被淘汰时，我我被要求输入一个字符串。
但它在单词行数后停止。
#include< iostream>
#include < string>
#include< iomanip>
#include< ctype.h>
using namespace std;
char wordCount（char []）;
int main（）
{
char cstring [81];
int index = 0;
cout<< Arshdeep Kaur撰写，Cs102 online\\\
;
cout<< " \ n输入一个字符串，不超过80个字符：\ n" ;;
cin.getline（cstring，81）;
cout<< " \ n该字符串中的单词数：" ;;
wordCount（cstring）;
cout<< index<< endl;
返回0;
}
char wordCount（char cstring []）
{
int index = 0;
int word = 0;
while（cstring [index]！=''\ 0''）
{
if（isspace（cstring [index]））
{
while（isspace（cstring [index]） ）
{
index ++;
}
}
if（isalnum（ cstring [index]））
{
word ++;
while（islower（cstring [index]））
{
word ++;
}
while（（isalnum（cstring [index]））||（ispunct（cstring [index]） ））
{
word ++;
}
}
index ++;
返回索引;
}
}
我认为我的wordCount函数存在问题
no error this time but when it excutes, i''m asked to input a string.
but it stops after the line number of words.
#include <iostream>
#include <string>
#include <iomanip>
#include <ctype.h>
using namespace std;
char wordCount(char []);
int main()
{
char cstring[81];
int index = 0;
cout << "Written by Arshdeep Kaur, Cs102 online\n";
cout << "\nEnter a string, 80 or fewer characters:\n";
cin.getline(cstring, 81);
cout << "\nThe number of words in that string: ";
wordCount(cstring);
cout << index << endl;
return 0;
}
char wordCount(char cstring[])
{
int index = 0;
int word = 0;
while (cstring[index] != ''\0'')
{
if (isspace(cstring[index]))
{
while (isspace(cstring[index]))
{
index++;
}
}
if (isalnum(cstring[index]))
{
word++;
while(islower(cstring[index]))
{
word++;
}
while((isalnum(cstring[index])) || ( ispunct(cstring[index])))
{
word++;
}
}
index++;
return index;
}
}
I think there is a problem in my wordCount funtion
