C++ program for Basic understanding of arrays.

a) How to input array and print a specific index's value.

#include<iostream>

using namespace std;

void main()

{

char n[10];

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

{

       cin>>n[i];

      

}

cout<<n[5];

cout<<endl;

system("pause");

}

 

Output:

b) How to input at a specific index

#include<iostream>

using namespace std;

void main()

{

float arr[7];

cout<<"enter the value of 5 index"<<endl;

cin>>arr[4];

cout<<"The value of 5 index"<<arr[4]<<endl;

system("pause");

}

Output:

c) How to set default value to whole array.

#include<iostream>

using namespace std;

void main()

{

int g[5];

for(int i=1;i<5;i++)

{

       g[i]=8;

       cout<<"Array = "<<g[i]<<endl;
