Write a program to search a value from an array in C.

     In computer science, a search allows the efficient retrieval of specific items from a set of items, such as a specific record from a database. The simplest, most general, and least efficient search structure is merely an unordered sequential list of all the items. Locating the desired item in such a list, by the linear search method, inevitably requires a number of operations proportional to the number n of items, in the worst case as well as in the...

Write a program to find factorial of a number in C.

         In mathematics, the factorial of a non-negative integer n, denoted by n!, is the product of all positive integers less than or equal to n. For example, 5! = 5  *  4  *  3  *  2  * 1 = 120. The value of 0! is 1, according to the convention for an empty product. The factorial operation is encountered in many areas of mathematics, notably in combinatorics, algebra, and mathematical analysis. Its most basic...

Write a program to find Fibonacci series of n numbers in C.

         In mathematics, the Fibonacci numbers or Fibonacci sequence are the numbers in the following integer sequence: 01, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144..... The Fibonacci spiral: an approximation of the golden spiral created by drawing circular arcs connecting the opposite corners of squares in the Fibonacci tiling; this one uses squares of sizes 1, 1, 2, 3, 5, 8, 13, 21, and 34. By definition, the first two numbers in the Fibonacci...
