Following is an example, which will show array declaration, assignment and accessing arrays in C++:

#include<iostream>

usingnamespacestd;

#include<iomanip>

usingstd::setw;

int main ()

{

int n[10];// n is an array of 10 integers

// initialize elements of array n to 0         

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

{

n[i]=i+100;// set element at location i to i + 100

}

cout<<“Element”<<setw(13)<<“Value”<<endl;

// output each array element’s value                     

for(int j =0; j <10;j++)

{

cout<<setw(7)<< j <<setw(13)<< n[ j ]<<endl;

}

return0;

}
