C Plus Plus Program to count letters and words

C Plus Plus Program to count letters and words

Counting the letters and words in a C++ program is a very simple and funny task. In this program we are going to develop a program in C++ which will count the letters and words in a phrase or a paragraph.

User will enter the phrase, sentence or a paragraph and this C++ program will count the letters and words and display them on screen.

                                                   Practical use of word counter

You have probably used the Microsoft Word. In Microsoft Word, there is functionality to count the words. These counted words are displayed on screen at left down corner, as you type the words. The same job has been done by this program. It not only counts the words but also letters. It is possibility that this program will be soon integrated in the MS Word.

 

                              C++ Program Code of Word and Letter Counter

//softoset.blogspot.com

#include<iostream>

#include<conio.h>

using namespace std;

int main()

{

int cwd=1;

int clet=0;

char ch='a';

cout<<"Enter a Phrase\n";

while(ch!='\r')

{

            ch=getche();

            if(ch==' ')

            cwd++;

            else

            clet++;

}

cout<<"\n\nWords ="<<cwd<<"\nLetters ="<<clet-1;

return 0;

}

 

                        Output of Letter and Word Counter Program in C++

 

We have run this code on our Dev C++, On execution of this code we have got the following output.

 

 

 

 

 

 

Look at the output you can see that the program has counted the exact and accurate number of words and the letters.

 

 

                                       Logic of Letter and Word Counter Program

 

There is a simple logic of this program. In main function, we have declared the two variables cwd to count words and clet to count letters. We have declared another variable ch of character data type to take the phrase or sentence form user. We have then use a while loop, which will take the characters unless the ‘\r’ is pressed, which is used in programming for the Enter key. Then in while loop ch=getche(); is used for the input and echoes the characters on screen. It is build in function in the library of conio.h so for using it you need to insert the conio.h header file. Then we have put a condition that if ‘ ‘ means a space bar then increase a word and else increase a letter.

Finally when user will press the enter key, while loop will terminate and out of while loop statement will print the number of letters and words on the screen. That’s it.
