C++ New Skills Practiced (Learning Goals)

Problem solving and debugging.

User-defined functions.

C++ strings.

Design a program that will read a series of titles from an input file (via Linux redirection), one per line.

The titles will be in an unorthodox mix of upper and lowercase letters and words may be separated by more than 1 blank.

Reformat each title so that

the first character (if it is a letter) of each word is capitalized and all remaining letters are lowercase

each word is separated by exactly one blank space

For example, "thE     CAT in tHe hat" becomes "The Cat In The Hat".

REQUIREMENTS

At least one function (in addition to main) must be used.

The string data type must be used.

Never use global variables.

Never use goto statements.

File can only be read one time.

The required output (displayed to the screen) from the program is

a list of the reformatted titles, one per line

ASSUMPTIONS

The input file will not be empty.

There will be one title per line.

Each title will consist of 1 or more words.

There will be no leading spaces before the first word in the title.

There will be at least 1 blank space between each word (there may be more).

There will be a linefeed after the last character of the last word in a title (no trailing blanks).

The program need only attempt to capitalize the first character of a word. For example, if a word in the title is "9TH", it should be reformatted to "9th". In other words, the program does not have to find the first letter in a word and capitalize it.

NOTES:

USE LINUX REDIRECTION. DO NOT USE FSTREAM.

Make sure you choose enough test data to ensure that your program meets all the requirements.

Sample terminal session:

[keys]$ more data4ten
the       5TH    wAVE
the cAT in thE   HAT
onE fish two FISh     red fISh bLuE Fish
[keys]$ g++ exercise10.cpp
[keys$ ./a.out < data4ten

The 5th Wave
The Cat In The Hat
One Fish Two Fish Red Fish Blue Fish

Here is a start to the program.
#include <iostream>
#include <string>
using namespace std;

int main()
{
string data;

cin >> data;
while (cin)
{

}
cin >> data;

}

ONE FUNCTION MUST BE USED. NO OTHER HEADER FILES ARE NEEDED. DO NOT USE FSTREAM. INPUT WILL BE TAKEN THROUGH LINUX REDIRECTION

Here is my code. The problem is, the onE fish two FISh     red fISh bLuE Fish keeps repeating when I put in the file through cin. Please help me fix my code:

#include <iostream>
#include <string>

using namespace std;
//Forward declaration
void FormatString(string);
void PrintString(string);

int main()
{  
   string data;   // take string input
   do
   {
       std::getline(std::cin,data);
       FormatString(data); // Call this function for formatting the string
   }while(!data.empty());// if no input it will terminate
  
   return 0;
}

void FormatString(string data)
{
   for(int i =0; data[i] !='';)
   {
       if((data[i] - 'a' >= 0 && data[i] - 'a' < 26) || (data[i] - 'A' >= 0 && data[i] - 'A' < 26))
       {
           data[i] = toupper(data[i]); // Convert first letter to upper
           i++;
       }
  
       while(data[i] != ' ' && data[i] != '')
       {
           data[i] = tolower(data[i]);// convert all letters in a word other than first to lower case
           i++;
       }

       if(data[i] == '') // if its end break
           break;
       else
           while(data[i] == ' ') i++; // skip multiple spaces
   }
   PrintString(data); // function for printing string
}

void PrintString(string data)
{
   int spaceCount =0;
   for(int i =0;i < data.length(); i++)
   {
       if(data[i] != ' ')
       {
           cout << data[i] ; // keep printing characters until you encounter space
           spaceCount = 0;
       }              
       else
       {
           if(spaceCount < 1)
               cout << data[i]; // Print only one space and consume other spaces
           spaceCount++;
       }
   }
   cout<<" ";
}

// output

Explanation / Answer

PROGRAM CODE:

#include <iostream>
#include <string>
using namespace std;
//Forward declaration
void FormatString(string);
void PrintString(string);
int main()
{
string data; // take string input
do
{
//reinitializing the string again - CHANGED
data = "";
std::getline(std::cin,data);
FormatString(data); // Call this function for formatting the string
}while(!data.empty());// if no input it will terminate
  
return 0;
}
void FormatString(string data)
{
for(int i =0; data[i] !='';)
{
if((data[i] - 'a' >= 0 && data[i] - 'a' < 26) || (data[i] - 'A' >= 0 && data[i] - 'A' < 26))
{
data[i] = toupper(data[i]); // Convert first letter to upper
i++;
}
  
while(data[i] != ' ' && data[i] != '')
{
data[i] = tolower(data[i]);// convert all letters in a word other than first to lower case
i++;
}
if(data[i] == '') // if its end break
break;
else
while(data[i] == ' ') i++; // skip multiple spaces
}
PrintString(data); // function for printing string
}
void PrintString(string data)
{
int spaceCount =0;
for(int i =0;i < data.length(); i++)
{
if(data[i] != ' ')
{
cout << data[i] ; // keep printing characters until you encounter space
spaceCount = 0;
}
else
{
if(spaceCount < 1)
cout << data[i]; // Print only one space and consume other spaces
spaceCount++;
}
}
cout<<" ";
}
// output
