Pseudocode to Count number of Words in Sentence for Beginners

In this article, we will write an Algorithm to count the number of words in a sentence and try to explain it in as simple words as we can.

Algorithm to Count no. of Words in Sentence for Beginners:


Input sentence
Read characters from 0 to EOL(End of Line) character for 'sentence' and store the count in variable 'sentence_length'
Initialize i=0, words_count=1;
Repeat Until i<=sentence_length
   if character at i position is space(' ')
          then words_count=words_count+1;
      i=i+1
   end if
print "Number of words is" + words_count

Input sentence

Read characters from 0 to EOL(End of Line) character for 'sentence' and store the count in variable 'sentence_length'

Initialize i=0, words_count=1;

Repeat Until i<=sentence_length

if character at i position is space(' ')

then words_count=words_count+1;

i=i+1

end if

print "Number of words is" + words_count

Output:


Input: This is my House
Number of words is 4

Input: This is my House

Number of words is 4

C++ Code:


#include <iostream>
using namespace std;
 
int main() {
	char str[80];
 
	cout << "Enter a string: ";
	cin.getline(str,80);
 
	int words = 0; // Holds number of words
 
	for(int i = 0; str[i] != '\0'; i++)
	{
		if (str[i] == ' ') //Checking for spaces
		{
			words++;
		}
	}
 
	cout << "The number of words = " << words+1 << endl;
 
	return 0;
}

#include <iostream>

using namespace std;

int main() {

char str[80];

cout << "Enter a string: ";

cin.getline(str,80);

int words = 0; // Holds number of words

for(int i = 0; str[i] != '\0'; i++)

{

if (str[i] == ' ') //Checking for spaces

{

words++;

}

cout << "The number of words = " << words+1 << endl;

return 0;

}

Python Code(for):


# Python program to Count Total Number of Words in a String

str1 = input("Please Enter your Own String : ")
total = 1

for i in range(len(str1)):
    if(str1[i] == ' ' or str1 == '\n' or str1 == '\t'):
        total = total + 1

print("Total Number of Words in this String = ", total)
