Question

Write a program that reads a text file then displays this menu

Display file

Show statistics (word count, line count, letter frequency with table format)

Search

Save file with another name

Exit

Note 0: The program should read the file in a dedicated format; each line should not exceed 100 chars -max- (use cin.getline() ) and some of your own thought to try to figure this out. Make sure a word is not split in half

Note1: The Search results display the lines in the text file where the results where found followed by [n1,n2,.. ] where n is the column number where the result is (are)

Note 2: The save file option will save the file in the new format; each line will be a 100 chars long

in c++ the file is over 100 chars long

Explanation / Answer

Solution:

Note: Please don't forget to save the Test.txt file in the same folder/package where you are executung the code.

code:

#include<iostream>
#include<fstream>
#include<conio.h>
#include<string.h>

using namespace std;
ifstream infile;
//display file
void displayFile()
{
   const int LINE_LENGTH = 100;
   infile.open("Test.txt");
char line[LINE_LENGTH];
if (infile.is_open())
{
   cout<<"File:"<<endl<<endl;
while (! infile.eof() )
{
infile.getline(line,LINE_LENGTH);//read line of 100 characters
cout<<line<<endl;
    }
infile.close();
}
else
cout<<" File Not exists"<<endl;
}
// start of main program
void findWord()
{
   int count=0;
   char ch[20],c[20];
   cout<<"Enter a word to count:";
    cin>>c;
infile.open("Test.txt");
   while(infile>>ch)//read word
   {  
   if(strcmp(ch,c)==0)
   count++;
   }
     
   cout<<"Occurrence of word ="<<count<<" times"<<endl;
   // closes the file
   infile.close();

  
}
void showStatistics()
{
   // running the loop until file will end
   char ch;
   int countChar=1;
   int countWords=1;
   int countLines=1;
   infile.open("Test.txt");
   while(infile.get(ch))//read character
   {
      
       if(ch==' ')
       {
           countWords++;//count number of words
       }
       else if(ch==' '){
           countWords++;//count number of words
           countLines++;//count number of Lines
       }
       else{          
           countChar++;//count number of characters
       }                  
      
   }
   // closes the file
   infile.close();

   _getch();
   // display the number of character, words and line
   cout<<" Lines words characters "<<endl;              
   cout<<countLines<<" "<<countWords<<" "<<countChar<<endl;
}
void saveFile()
{
   infile.open("Test.txt");
   const int LINE_LENGTH = 100;  
char line[LINE_LENGTH];
ofstream outfile("Output.txt");
if (infile.is_open())
{
   cout<<"File:"<<endl<<endl;
while (! infile.eof() )
{
infile.getline(line,LINE_LENGTH);//read line of 100 characters
outfile<<line<<endl;//print on other file
    }
infile.close();
}
else
cout<<" File Not exists"<<endl;
}
int main()
{  
   // open the file for input.
   ifstream infile("test.txt");
  
   // create the stream in read-only mode
   if(!infile) {
       cout << "Cannot open file for reading. ";
       _getch();
       return 1;
   }   
   // declares character and integer variables
   char c;
   int ch;  
   int f=true;
   while(f)
   {
       cout<<"Menu: 1.Display file 2.Show statistics 3.Search 4.Save file 5.Exit "<<"Enter choice: ";
       cin>>ch;//read choice
       switch(ch)
       {
           case 1:
               displayFile();
               break;
           case 2:
               showStatistics();              
               break;
           case 3:
               findWord();
               break;
           case 4:
               saveFile();
               break;
           case 5:f=false;
               cout<<"Exiting...."<<endl;
               break;
           default:cout<<"Enter correct choice."<<endl;      
       }
   }

   return 0;
}
