Number is an arithmetical value, expressed by a word, symbol, or figure, representing a particular quantity and used in counting and making calculations. This program allows the user to enter any number and then finds the square root of that number using math function sqrt () This program uses the math function findSQRT(int number) to find the square root of a number. As we all know √number = number½.

It is a well-known method that is used every day by many blogs. The speech here is from DoFollow's backlinks via blog comments. However, many blog networks such as Blogspot, WordPress, Typepad, etc., only leave nofollow comments because many have to stick to the Google webmaster rules of nofollow. However, there are some bloggers who are making the effort to use special plugins or applications to remove the evil rel = "nofollow" tag from their default blog platform. Many want to increase their blog traffic.

This program evaluates The ASCII value of inserted character. In this program, the user is asked to enter 'A' character. The character is stored in variable a. When %d format string is used, 65 (the ASCII value of G) is displayed. When %c format string is used, 'A' itself is displayed.

The factorial of a positive number n is calculated by: The factorial of n (n!) = 1 * 2 * 3 * 4....n In this program we will find the factorial of a number where the number should be entered by the user. Factorial is sequence of a number whose multiply all previous number.

In this program, User Enter a number and check whether the given number is even or odd. Then, after successful compilation displays to check it is Odd or Even on the screen. The output of this Program is given below:Enter any number to check it is even or odd: 4153 is Even.Enter any number to check it is even or odd: 33 is Odd.

This Program adds previous two numbers value to compute the next number value. In this program Fibonacci series is calculated using recursion, with seed as 0 and 1. In the code Fibonacci function calls itself with a lesser value several times. An termination condition is very important to recursion function, i.e. n == 0 and n == 1 or the recursive call would be infinite leading to stack overflow error.

This C program allows the user to enter the Principal Amount, Rate of Interest, and the Number of years. By using those values, this C Program will calculate the Simple Interest using following formula: Simple Interest = (Principal Amount * Rate of Interest * Number of years) / 100.

This Program reversed any number such as Integer, float, or decimal in their equivalent. After the successful compilation of the program, a message is displayed on the screen as Please! Enter a string that you want to reverse: Suppose, User, entered 11001 then again a message is displayed as The Equivalent Reversed Number is 10011. Read more...

To get the output of the this Program, User will Enter temperature in Celsius: 100 Then, Compiler will convert it into Fahrenheit automatically. The final output shown onto the screen is as follows: Enter temperature in Celsius: 100 100 Celsius = 212.00 Fahrenheit

In this Program, the if…else statement is used to check whether an alphabet entered by the user is a vowel or a constant. The five letters A, E, I, O and U are called vowels. All other letters except these 5 vowel letters are called consonants. This program assumes that the user will always enter an alphabetic character.

This Program runs a loop from 2 to 100 and checks for each current number within range that it is prime or not. After the successful execution of the program it displays the list of all prime numbers from 2 to 100. As we know that 1 is not a prime number so we don't need to check it.

This Program stores two integers one by one into the int datatype. After the successful swapping of numbers it will exchange the value of them at once or you can say that it assign a's value to b and b's value to a.

In the successful compilation of the program, a message is displayed on the screen as Please! Enter a string to check if it's a palindrome:This program entered a string by user then store it into a variable after that found its reversed and store it in to another variable if both variables are same then we can say that inputed string is palindrome otherwise that is not a palindrome.

This program reversed the entered string that means opposite of the previous string sequence.

In this Program, The first two elements are respectively started from 0 , 1, and the other numbers in the series are generated by adding the last two numbers of the series using looping. These numbers are stored in an array and printed as output.
