EXERCISE - 5

A) Write a program to illustrate function overloading. Write 2 overloading functions for adding two numbers.
B) Write a program illustrate function template for power of a number.
C) Write a program to illustrate function template for swapping of two numbers.
A) AIM:Write a program to illustrate function overloading. Write 2 overloading functions for adding two numbers.
SOURCE CODE:
#include<iostream>
using namespace std;
int add(int,int);
float add(float,float);
int main()
{
    int i1,i2,i3;
    float f1,f2,f3;
    cout<<"Enter two integers:"<<endl;
    cin>>i1>>i2;
    cout<<"Enter two floating point values:"<<endl;
    cin>>f1>>f2;
    i3=add(i1,i2);
    f3=add(f1,f2);
    cout<<"Sum of two integers:"<<i3<<endl;
    cout<<"Sum of two floating points:"<<f3<<endl;
}
int add(int a,int b)
{
    return a+b;
}
float add(float a,float b)
{
    return a+b;
}
OUTPUT:
Enter two integers:
9
6
Enter two floating point values:
2.6
8.5
Sum of two integers:15
Sum of two floating points:11.1
B) AIM:Write a program illustrate function template for power of a number.
SOURCE CODE:
#include<iostream>
using namespace std;
template<typename T>
T power(T a,T b)
{
    T result=1;
    while(b>0)
    {
        result=result*a;
        b--;
    }
    return result;
}
int main()
{
    int n1,n2;
    cout<<"Enter two numbers:"<<endl;
    cin>>n1>>n2;
    cout<<n1<<" power "<< n2 <<" is "<<power(n1,n2)<<endl;
}
OUTPUT:
Enter two numbers:
3
5
3 power 5 is 243
C) AIM:Write a program to illustrate function template for swapping of two numbers.
SOURCE CODE:
#include<iostream>
using namespace std;
template<typename T>
T swap(T *a,T *b)
{
    T temp;
    temp=*a;
    *a=*b;
    *b=temp;
}
int main()
{
    int n1,n2;
    cout<<"Enter two numbers:"<<endl;
    cin>>n1>>n2;
    cout<<"Before swapping n1="<<n1<<"\tn2="<<n2<<endl;
    swap(&n1,&n2);
    cout<<"After swapping n1="<<n1<<"\tn2="<<n2<<endl;
}
OUTPUT:
Enter two numbers:
9
6
Before swapping    n1=9    n2=6
After swapping    n1=6    n2=9
