QBASIC program to count the total number of words from input string

Introduction:

Are you looking for a way to count the total number of words in an input string using QBASIC program? Look no further! In this article, we will guide you through the process of creating a QBASIC program to count the number of words in any given input string. Whether you're a beginner or an experienced QBASIC programmer, this guide is perfect for you.

Understanding the Problem

Before we start writing the QBASIC program, we need to understand the problem at hand. The task is to write a program that takes an input string from the user and counts the total number of words in that string. A word is defined as a sequence of characters separated by spaces.

Step-by-Step Guide to Writing the QBASIC Program

Now that we understand the problem, let's start with writing the QBASIC program. The following are the steps we will take to write the program:

Step 1: Accepting the Input String

Step 2: Initializing the Counter

Step 3: Counting the Words

Step 4: Displaying the Result

Writing program (Coding)

CLS

INPUT "Enter any string"; w$

FOR x = 1 TO LEN(w$)

m$ = MID$(w$, x, 1)

IF m$ = " " THEN w = w + 1

NEXT x

PRINT "Total word in string="; w + 1

END

Explanation of the program:

• The program starts by clearing the screen using the command CLS.
• Then, the program prompts the user to enter any string using the INPUT statement and stores the input in a variable called w$.
• After that, the program runs a loop from 1 to the length of the input string (LEN(w$)). Inside the loop, it uses the MID$ function to extract each character of the string one by one and store it in a variable called m$.
• If the character is a space (" "), it means a word has ended, so the program increments the word counter variable (w) by 1.
• After the loop is completed, the program prints the total number of words in the input string by adding 1 to the value of the word counter variable (w + 1).
• Finally, the program ends using the END statement.

We can write the above program using SUB and FUNCTION procedure
