Array in C++

This is a new post about the important concept of C++ Programming : - ARRAY


//WRITE A PROGRAM TO ENTER TEN NUMBERS IN AN ARRAY AND DISPLAY THEM
#include<iostream.h>
#include<conio.h>
void main()
{
int arr[10],i;
cout<<"Enter Ten numbers in an array"<<endl;
for(i=0;i<10;i++)
{
cin>>arr[i];
}
cout<<"The array elements are "<<endl;
for(i=0;i<10;i++)
{
cout<<arr[i]<<endl;
}
getch();
}

//WRITE A PROGRAM TO ENTER TEN NUMBERS IN AN ARRAY AND DISPLAY THEIR SUM

#include<iostream.h>

#include<conio.h>

void main()

{

int arr[10],i,sum=0;

cout<<"Enter Ten numbers in an array"<<endl;

for(i=0;i<10;i++)

{

cin>>arr[i];

sum=sum+arr[i];

}

cout<<"The sum is "<<sum<<endl;

getch();

}

//WRITE A PROGRAM TO ENTER TEN NUMBERS IN AN ARRAY AND DISPLAY THE BIGGEST OF THEM

#include<iostream.h>

#include<conio.h>

void main()

{

int arr[10],i,big=0;

cout<<"Enter Ten numbers in an array"<<endl;

for(i=0;i<10;i++)

{

cin>>arr[i];

if(arr[i]>big)

big=arr[i];

}

cout<<"The biggest number is "<<big<<endl;

getch();

}

//WRITE A PROGRAM TO ENTER TEN NUMBERS IN AN ARRAY AND DISPLAY THE SMALLEST OF THEM

#include<iostream.h>

#include<conio.h>

void main()

{

int arr[10],i,small;

small=arr[0];

cout<<"Enter Ten numbers in an array"<<endl;

for(i=1;i<10;i++)

{

cin>>arr[i];

if(arr[i]<small)

small=arr[i];

}

cout<<"The smallest number is "<<small<<endl;

getch();

}
