C++ program of template

In this program we will clear the concept of template in c++

//Code starts 

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

using namespace std;

template <class T>

void abc(T* array,int size)
{
for(int i=0;i<size;i++)
{
cout<<array[i]<<",";
}
}

int main()
{
float ar[5]= {0.3,2.5,6.3,5.9,6.6};

int arr[5];


for(int i=0;i<5;i++)
{
cout<<"Enter integer : ";
cin>>arr[i];
}

abc(ar,5);
cout<<endl;
abc(arr,5);

getch();

}
//Code ends

C++ program of entering employee data through functions and structure

In this program we will learn how to enter employee data through functions using structure.
The code is given below.

//code starts
#include <iostream>
#include <conio.h>

using namespace std;

struct emp
{
int id,salary;
char name[20];
};

void input (emp &emp1);

void show (emp emp1);

int main()
{
emp emp1;

input (emp1);

show (emp1);

     getch();

}

void input (emp &emp1)
{
cout<<"Enter Employee ID : "<<endl;
cin>>emp1.id;

cout<<"Employee Name : "<<endl;
cin>>emp1.name;

cout<<"Enter Salary :"<<endl;
cin>>emp1.salary;
}

void show (emp emp1)
{

cout<<"ID: "<<emp1.id<<endl;

cout<<"Name: "<<emp1.name<<endl;

cout<<"Salary: "<<emp1.salary;
}
//code ends

C++ Program of Exponential using Functions

In this program we will learn how to take exponential of a variable e.g 10^2.

The code is given below.

//Code starts

#include<iostream>

#include<conio.h>

using namespace std;

int expo(int b, int p)

{

 int temp=1;        //taking a temporary variable

 for(int i=1; i<=p; i++) //for loop starts

 {

  temp=temp*b;

 }

 return temp;  //returning value of temporary variable

}

int main()   //main starts

{

 int c,d;

 cout<<"Enter Base to Find its Exponential : ";

 cin>>c;

 cout<<"Enter Power to Find its Exponential : ";

 cin>>d;

 cout<<"Answer = "<<expo(c,d); // Function calling

getch();

}

//Code ends
