For Calculate Power of any number, multiply particular number by itself on the basis of power.



For Calculate Power of any number, multiply particular number by itself on the basis of power.
Suppose you want to calculate 2^3 is 2*2*2=8.

For calculating the power of any number user have four possibilities to input values.

    Value of power is +ve
    Value of Power is -ve
    Value of Base is +ve
    Value of Base is -ve
    Value of power is 0

This code only work for when we input +ve power, +ve base value, -ve base value. But it's not work when we enter -ve power value.

#include<iostream.h>
#include<conio.h>

 void main()
  {
   int b,p,i,pow=1;
   clrscr();
   cout<<"Enter base and power: ";
   cin>>b>>p;
   for(i=p;i>0;i--)
   {
   pow=pow*b;
   }
   cout<<"power is: "<<pow;

  getch();
  }

C++ Program Reverse an Integer Number
This takes an integer input from the user and stores it in 'variable n'. Then the while loop is iterated until n != 0 is false. In each iteration, the remainder when the value of n is divided

Whether a Path Exists Between two Given
We create a queue for BFS. Mark the current node as visited and enqueue it. It will be used to get all adjacent vertices of a vertex. Get all adjacent vertices of the dequeued vertex s. If

C++ Language Samples Separate Chaining
Internal method to test if a positive number is prime. Not an efficient algorithm and Internal method to return a 'prime number' at least as large as n. Assumes "n > 0". Insert item x into

C++ Program Three Dimensional 3D Array
3D array contains three for loops. to initialize and "print three dimensional" array, you have to use three for loops. Third for loop forms 1D array, Second for loop forms 2D array and the

Order of Constructor Call in C++ language
In The C++ programming, When a default or parameterized constructor of a derived class is called, the "Default Constructor" of a base class is called automatically. As you create an

Programming Code Function Call by Value
C Programming Language Function call by value is the default way of calling a function. Before we discuss function call by value, lets understand the terminologies that we will...

Find the Number of Integers Divisible by 5
C Program to which calculates the number of integers divisible by 5 in the given range. This C program takes the range as input and finds the number of integers divisible by 5 in range.

Swap Array Element and Reverse an Array
To reverse an array in C++ programming, you have to ask to the user to enter the array size and array elements. Now start swapping the array elements. Make a variable say temp of
