C Program to find Power of a Number using Recursion

C Program to find Power of a Number using Recursion

The following C program, using recursion, finds the power of a number. The power of a number is the number multiplied to itself for the number of times it has been raised to Eg: 9^3 is 729

    #include <stdio.h>

    long power (int, int);

    int main()

    {

        int pow, num;

        long result;

        printf("Enter a number: ");

        scanf("%d", &num);

        printf("Enter it's power: ");

        scanf("%d", &pow);

        result = power(num, pow);

        printf("%d^%d is %ld", num, pow, result);

        return 0;

    }

    long power (int num, int pow)

    {

        if (pow)

        {

            return (num * power(num, pow - 1));

        }

        return 1;

    }

Finds Independent Sets in Graph by Graph - Code finds 'largest independent' set by graph coloring. In graph theory, an independent set or stable set is a set of vertices in a graph, no two of which are adjacent. That is, it is a set I

C Computing the Product of Two Matrices - Code computes the product of two matrices. This program accepts the 2 matrices and then find the product of 2 matrices. Develop functions to read a matrix, display a matrix

C Programming codings Else..If Statement - C Language The else..if statement is useful when you need to check multiple conditions within the program, nesting of if-else blocks can be avoided using else..if statement. else

Program print Strong Numbers in a Range - Strong number is special number whose sum of Factorial of Digits is equal to the original number. For example: 145 is strong number. Since, 1! + 4! + 5! = 145 Logic to print Strong

Generate Random Subset by Coin Flipping - Prints a 'subset' of the given array using coin flipping method. The time complexity of this algorithm is O(n). Takes the input of 'n' data element and prints a possible subset. that, it

Implementing Hash Table Chaining Binary - Adding element to a node and check if node contains element. 'Adding string' in the table. Check if table contains string. Enter String to be inserted. Display table chained with binary

Program Add Two Numbers Using Pointer - In program we're going to accept 2 numbers from user using pointer. After accepting Two Numbers we are going to add Two Numbers by using "De-reference Operator" in Pointer.

C Number of Occurrences of an Element in - Code Count the number of Occurrences of an element in the linked list using recursion. This C Program uses recursive function & finds the occurrence for an element in an Unsorted list.
