Explanation of the Odd Number do-while Loop Program
This program prints all odd numbers starting from 1 up to a user-defined limit. It uses a do-while loop, which ensures that the loop body runs at least once before checking the condition.
The program begins with the first odd number (1) and increments by 2 each time. This continues until the value becomes greater than the last number entered by the user.
What the Program Does
- Starts with the first odd number (fno = 1).
- Asks the user to enter the last number (lno).
- Uses a do-while loop to print numbers like 1, 3, 5, 7, etc.
- Increments by 2 to ensure only odd numbers are printed.
- Stops when the next odd number exceeds the last number.
- Uses getch() to pause the screen (Turbo C feature).
Example Input
Enter the last number: 15
Example Output
1 3 5 7 9 11 13 15
Summary: This program prints a sequence of odd numbers by repeatedly adding 2, using a do-while loop. It is a simple demonstration of loop control, number sequences, and Turbo C input/output functions.
