Task 5:

Write a Program that takes age in years and displays age in months and days
1 year = 12 months
1 year= 365 days

Code:

#include<iostream>
using namespace std;
int main()
{
	int age;
	cout<<"Enter Your age in Years : ";
	cin>>age;
	int months,days;
	months=age*12;
	days=age*365;
	cout<<"\nYour Age in Months : "<<months<<endl;
	cout<<"\nYour Age in Days : "<<days<<endl;
	return 0;
}

Output:

Enter Your age in Years : 23

Your Age in Months : 276

Your Age in Days : 8395

Task 6:

Write a Program that Takes input From user and displays square and cube of that number
Use both methods..
Without using pow function,
Using power function

Code:

#include<iostream>
#include<math.h>
//this header file contains all functions of mathematics..
//e.g cos,sin,tan,sqrt,power,exp,etc
using namespace std;
int main()
{
	//declare variable
	double n;
	//taking input
	cout<<"Enter Number : ";
	cin>>n;
	//find cube and square without using pow function
	double sq,cube;
	sq=n*n;
	cube=n*n*n;
	cout<<"\nSquare of "<<n<<" is "<<sq<<endl;
	cout<<"\nCube of "<<n<<" is "<<cube<<endl;
	cout<<"\n---------using Builtin Function---------"<<endl;
	//pow(number,power)
	//this function accepts two parameters.. one is number and the 2nd is its
	//power
	sq=pow(n,2);
	cube=pow(n,3);
	cout<<"\nSquare of "<<n<<" is "<<sq<<endl;
	cout<<"\nCube of "<<n<<" is "<<cube<<endl;
	return 0;
}

Output:

Enter Number : 6

Square of 6 is 36

Cube of 6 is 216

---------using Builtin Function---------

Square of 6 is 36

Cube of 6 is 216
