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.

Beauty lies in the eyes of beholder

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
