So let’s dive in and explore the intricacies of the “C program to find total words in a string.”

What is a String?

Before we delve into the details of the program, let’s briefly discuss what a string is in the context of programming.

In C, a string is a sequence of characters enclosed within double quotes, such as “Hello, World!” or “OpenAI is amazing!” Strings are widely used to store and manipulate textual data in programs.

The Program: Finding Total Words in a String

To begin with, let’s take a look at the C program that calculates the total number of words in a given string:

#include <stdio.h>

int countWords(char str[]) {
    int count = 1; // Assuming the string has at least one word
    int i;

    for (i = 0; str[i] != '\0'; i++) {
        if (str[i] == ' ' || str[i] == '\n' || str[i] == '\t') {
            count++;
        }
    }

    return count;
}

int main() {
    char str[100];

    printf("Enter a string: ");
    fgets(str, sizeof(str), stdin);

    printf("Total words in the string: %d\n", countWords(str));

    return 0;
}

Let’s break down the program and understand how it works.

1. Including the Necessary Libraries

The program begins with the inclusion of the <stdio.h> library, which provides the standard input-output functions required for the program to work.

2. Defining the countWords Function

The countWords function takes a string as input and returns the total number of words in that string.

It accomplishes this by iterating through each character in the string and counting the number of spaces, newline characters, and tabs it encounters.

The assumption here is that words in the string are separated by either a space, a newline, or a tab.

3. Implementing the main Function

The main function is where the actual execution of the program takes place. It prompts the user to enter a string and stores it in the str variable using the fgets function.

The fgets function reads characters from the standard input (keyboard) and stores them in the specified string.

Once the string is obtained, the program calls the countWords function and passes the string as an argument.

The return value of countWords is then displayed as the output, representing the total number of words in the given string.
