Last update on December 20 2024 12:32:33 (UTC/GMT +8 hours)

Write a C++ program to count all the words in a given string.

Visual Presentation:

Sample Solution:

C++ Code :

#include <iostream> // Including input/output stream library
#include <string> // Including string handling library
using namespace std; // Using the standard namespace

// Function to count the number of words in a string
int Word_count(string text) {

	int ctr = 0; // Initializing a counter variable to count words

	// Loop through the string and count spaces to determine words
	for (int x = 0; x < text.length(); x++) {
		if (text[x] == ' ') // Checking for spaces to count words
			ctr++; // Increment the counter for each space found
	}
	return ctr + 1; // Return the count of words by adding 1 to the total number of spaces (plus 1 for the last word without a trailing space)
}

// Main function
int main() {
	// Displaying the count of words in different strings
    cout << "Original string: Python, number of words -> " << Word_count("Python") << endl;
    cout << "\nOriginal string: CPP Exercises, number of words -> " << Word_count("CPP Exercises") << endl;
    cout << "\nOriginal string: After eagling the Road Hole on Thursday, he missed an 8-footer for birdie Friday., \nnumber of words -> ";
	cout << Word_count("After eagling the Road Hole on Thursday, he missed an 8-footer for birdie Friday.") << endl;
    return 0; // Return 0 to indicate successful completion
}

Sample Output:

Original string: Python, number of words -> 1

Original string: CPP Exercises, number of words -> 2

Original string: After eagling the Road Hole on Thursday, he missed an 8-footer for birdie Friday.,
number of words -> 14
