計算數據文件中字符串出現次數的 Turbo C++ 程序總是（錯誤地）返回零。

Question

我用 Turbo C++ 編寫了一個程序，計算數據文件中字符串“HOTEL”的出現次數。 但它總是給我 0 值。我做錯了什么？

//PROGRAM TO COUNT NO OF OCCURENCES OF A STRING IN A DATA FILE
#include<fstream.h>
#include<conio.h>
#include<string.h>
void main()
{
ifstream ifs;
ifs.open("DATA.DOCX",ios::in|ios::nocreate);
if (!ifs)
 { 
    cout<<"SORRY! FILE DOES NOT EXIST";
 }   
else
 {
int count=0;
char compare[20];
while (ifs.eof())
 {
    ifs>>compare;
    if (strcmp(compare,"HOTEL")==0)
     count++;
 }
ifs.close();
cout<<"NO OF OCCURENCE OF STRING 'HOTEL' = "<<count;
  }
getch();
}

Answer 1

正如提問者所說，問題是文件名是“DATA.DOCX”，需要更改為“DATA.TXT”。

//PROGRAM TO COUNT NO OF OCCURENCES OF A STRING IN A DATA FILE
#include<fstream.h>
#include<conio.h>
#include<string.h>
void main()
{
ifstream ifs;
ifs.open("DATA.TXT",ios::in|ios::nocreate);
if (!ifs)
 { 
    cout<<"SORRY! FILE DOES NOT EXIST";
 }   
else
 {
int count=0;
char compare[20];
while (ifs.eof())
 {
    ifs>>compare;
    if (strcmp(compare,"HOTEL")==0)
     count++;
 }
ifs.close();
cout<<"NO OF OCCURENCE OF STRING 'HOTEL' = "<<count;
  }
getch();
}
