Calculating Factorial Using Recursion in C

Factorial: its a mathematical function defined as 4!=4x3x2x1=120. Yes just like that. It will multiply all numbers before the given numbers till 1(Worst definition ever).


Method: recursive method is pretty easy too. because n!=n*(n-1)! and we know that 1!=1.
so Terminating condition: at n==1 result =1.
Recursive definition : n!=n*(n-1)!
Code in C:  
#include<stdio.h>
int factorial(int x)
{
    if(x==1)
    {
        return(1);
    }
    else
    {
        return(x*factorial(x-1));
    }
}
int main()
{
    int n;
    printf("\n Enter the number to calculate its factorial=");
    scanf("%d",&n);
    printf("\n Factorial of number =%d",factorial(n));
}

Overloading Unary Operator in C++

In this Example I will demonstrate overloading a unary operator. The overloading is done in similar way as we did for binary operator. In this example I will be using a Vector Class. The operator we are going to over load is the unary "~" (tilde) operator. although you can use any unary overloadable operator. Method: In this example the overloaded operator will be the part of the class i.e. the over loaded definition will be a member function. (As we know overloading can be done using non member functions too). So the unary operator will not have any arguments in it. We will overload ~ operator so that it will reflect the vector so that its z component becomes x component and vice versa. So input vector will be 2i+3j+5k and its output vector will be 5i+3j+2k. although you can do anything you like. Code: # include < iostream > using namespace std ; class vector { int x , y , z ;      public : vector ( ) { x = y = z = 0 ; ...

calculating leap year in c using if else

Most new students get really confused when it comes to calculating Leap year in C. It is given as an exercise to enhance their knowledge about using if else usages. This can be calculated using Logical operators too. But using if else provides clearer ways to calculate it. Both of the methods can be implemented in C/C++ program. Here we will discuss the if else method in C/C++
