For Loop in C++ Programming

Introduction

• Channel Subscription Advice: Subscribe to the "Learn Coding" channel to learn C++ programming.
• Today's Topic: For Loop

What is a For Loop?

• Syntax and Example Program: We will understand the syntax of the for loop and see an example program.
• Flowchart: We will also look at the flowchart of the for loop.

Usage of For Loop

• When to Use:
  • When we need to perform initialization, condition, and increment/decrement in a single line.
  • When the start and end points are known beforehand.
• Major Benefits: The for loop is used because it is the most frequently used loop, and it is simple.

Execution of For Loop

• Start of the Loop: Decide how many times the loop will execute in the first line itself.
• Increment/Decrement: It is your choice whether you will increment or decrement.

Flowchart

• Start: The loop's condition is checked.
• Statement Execution: If the condition is true, the statement is executed.
• Increment/Decrement: The value increases or decreases.
• Repeat until Condition: This action continues as long as the condition remains true.

Using For Loop in a Program

• Printing Multiplication Table:
  • A variable num is taken, where a number is input.
  • Use cout to prompt the message.
  • The loop variable i is incremented from 1 to 10.
  • During program execution, input a number and the multiplication table will be printed.

Making the Program Attractive

• Program Design:
  • First print the number, then the multiplication symbol, then i, and finally the equals symbol and the result.
  • You can use the message "Multiplication Table of".
  • Use endl for newline.

Conclusion

• Use the for loop to print the multiplication table of any number.
• The program can be made more attractive for the user.
• If you find the program correct, you can make it even better.
