Program to count the total number of words in a string

Explanation

In this program, we need to count the words present in the string.

Total number of words present in the string is 7.

Algorithm

Define a string.
To counts the words present in the string, we will iterate through the string and count the spaces present in the string. As each word always ends with a space.
If a string starts with a space, then we must not count the first space as it is not preceded by a word.
To count the last word, we will increment the count by 1.

Solution

Python

sentence = "Beauty lies in the eyes of beholder";
wordCount = 0;
 
for i in range(0, len(sentence)-1):
    #Counts all the spaces present in the string
    #It doesn't include the first space as it won't be considered as a word
    if(sentence[i] == ' ' and sentence[i+1].isalpha() and (i > 0)):
        wordCount = wordCount + 1;
        

#To count the last word present in the string, increment wordCount by 1
wordCount = wordCount + 1;
 
#Displays the total number of words present in the given string
print("Total number of words in the given string: " + str(wordCount));

Output:

Total number of words in the given string: 7

C

#include <stdio.h>
#include <string.h>
 
int main()
{
    char sentence[] = "Beauty lies in the eyes of beholder";
    int wordCount = 0;
    
    for(int i = 0; i < strlen(sentence)-1; i++) {
        //Counts all the spaces present in the string
        //It doesn't include the first space as it won't be considered as a word
        if(sentence[i] == ' ' && isalpha(sentence[i+1]) && (i > 0)) {
            wordCount++;
        }
    }  
    //To count the last word present in the string, increment wordCount by 1
    wordCount++;
    
    //Displays the total number of words present in the given string
    printf("Total number of words in the given string: %d", wordCount);
 
    return 0;
} 

Output:

Total number of words in the given string: 7

JAVA

public class CountWords 
{
    public static void main(String[] args) {
        String sentence = "Beauty lies in the eyes of beholder";
        int wordCount = 0;
        
        for(int i = 0; i < sentence.length()-1; i++) {
            //Counts all the spaces present in the string
            //It doesn't include the first space as it won't be considered as a word
            if(sentence.charAt(i) == ' ' && Character.isLetter(sentence.charAt(i+1)) && (i > 0)) {
                wordCount++;
            }
        }
        //To count the last word present in the string, increment wordCount by 1
        wordCount++;
        
        //Displays the total number of words present in the given string
        System.out.println("Total number of words in the given string: " + wordCount);
    }
}

Output:

Total number of words in the given string: 7

C#

using System;
                    
public class CountWords
{
    public static void Main()
    {
        String sentence = "Beauty lies in the eyes of beholder";
        int wordCount = 0;
        
        for(int i = 0; i < sentence.Length-1; i++) {
            //Counts all the spaces present in the string
            //It doesn't include the first space as it won't be considered as a word
            if(sentence[i] == ' ' && Char.IsLetter(sentence[i+1]) && (i > 0)) {
                wordCount++;
            }
        }
        //To count the last word present in the string, increment wordCount by 1
        wordCount++;
        
        //Displays the total number of words present in the given string
        Console.WriteLine("Total number of words in the given string: " + wordCount);
    }-
}           

Output:

Total number of words in the given string: 7

PHP

<!DOCTYPE html>
<html>
<body>
<?php
$sentence = "Beauty lies in the eyes of beholder";
$wordCount = 0;
 
for($i = 0; $i < strlen($sentence)-1; $i++) {
    //Counts all the spaces present in the string
    //It doesn't include the first space as it won't be considered as a word
    if($sentence[$i] == ' ' && ctype_alpha($sentence[$i+1]) && ($i > 0)) {
        $wordCount++;
    }
}
//To count the last word present in the string, increment wordCount by 1
$wordCount++;
 
//Displays the total number of words present in the given string
print("Total number of words in the given string: " . $wordCount);
?>
</body>
</html>

Output:

Total number of words in the given string: 7
