Study Notes

Factorial Calculation Algorithm

Starts by reading a number n.
Initializes counter i to 1 and factorial variable fact to 1.
Uses a loop to calculate the factorial: fact = fact * i while i is less than or equal to n.
Outputs the computed factorial value.

Armstrong Number Check Algorithm

Starts by reading a number and storing it as temp.
Calculates the sum of the digits raised to the power of the number of digits in temp.
Compares the calculated sum with the original number to determine if it is an Armstrong number.
Displays output based on the comparison.

Maximum Number from Three Inputs Algorithm

Begins with receiving three numbers: a, b, and c.
Compares a with b and c to determine the largest.
Outputs which number is the largest among the three.

Odd or Even Number Check Algorithm

Starts by reading an integer.
Checks if the number is divisible by 2.
Prints whether the number is even or odd based on the divisibility check.

Maximum Number from Two Inputs Algorithm

Starts by reading two numbers: a and b.
Compares the two numbers to find the maximum.
Outputs which number is the maximum.

Finding Even Numbers from 1 to N Algorithm

Begins by reading an integer N from keyboard input.
Initializes a counter i to 1 and loops through numbers.
Checks each number if it is even.
Outputs even numbers from 1 to N.

Description

This quiz covers algorithms for calculating factorials, checking Armstrong numbers, finding the maximum of three numbers, and determining if a number is odd or even. Test your understanding of these fundamental programming concepts and improve your algorithmic thinking.
