A positive number is called armstrong number if it is equal to the sum of cubes of its digits.Examples: 153 is Armstrong, (1*1*1)+(5*5*5)+(3*3*3) = 153

Factorial is the product of all positive integers less than or equal to n. Examples: 4! = 4 × 3 × 2 × 1 = 24

Factor a number or algebraic expression that divides another number or expression evenly—i.e., with no remainder. For example, 3 and 6 are factors of 12 because 12 ÷ 3 = 4 exactly and 12 ÷ 6 = 2 exactly. The other factors of 12 are 1, 2, 4, and 12. Factors of 12: 1, 2, 3, 4, 6, 8, 12.

A series of numbers in which each number ( Fibonacci number ) is the sum of the two preceding numbers. The simplest is the series 0, 1, 1, 2, 3, 5, 8, etc.

The greatest common divisor (gcd) of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers. For example, the gcd of 8 and 12 is 4.

A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.

If a number=1234, then reverse of number is 4321.

If a number enter 5462 then sum of theses digits 5+4+6+2 = 17.

A palindromic number is a number that remains the same when its digits are reversed. Like 16461, for example.

A tech number can be tech number if its digits are even and the number of digits split into two number from middle then add these number if the added number’s square would be the same with the number it will called a Tech Number.

WAP that calculates the Simple Interest and Compound Interest. The Principal, Amount, Rate of Interest and Time are entered through the keyboard.

WAP that swaps values of two variables using a third variable.

WAP that accepts marks of five subjects and finds percentage and prints grades according to the following criteria: Between 90-100%————–Print „A‟ 80-90%—————————-Print „B‟ 60-80%—————————Print „C‟ Below 60%———————-Print „D‟

WAP to print the Fibonacci series.A series of numbers in which each number ( Fibonacci number ) is the sum of the two preceding numbers. The simplest is the series 0, 1, 1, 2, 3, 5, 8, etc.

WAP to check whether the entered number is prime or not.A prime number is a natural number greater than 1 that cannot be formed by multiplying two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself.

WAP to find the sum of digits of the entered number.

WAP to print Armstrong numbers from 1 to 1000. A positive number is called armstrong number if it is equal to the sum of cubes of its digits.Examples: 153 is Armstrong, (1*1*1)+(5*5*5)+(3*3*3) = 153

WAP to convert binary number into decimal number and vice versa.

WAP that inputs two arrays and saves sum of corresponding elements of these arrays in a third array and prints them.

WAP to search an element in a array using Linear Search.
