c)      Set the value of 3^rd serial number to the addition of first two serial numbers.

d)     Display the serial number on 2^nd index

e)     Print the whole array

Answer 1

#include <iostream>
using namespace std;
 
int main() {
// a) Initialize an array of 8 entries for serial number
    const int N =8;
    int arr[N] = {0, 1, 2, 3, 4, 5, 6, 7};
    int i;
    
// b) Set the value of 5th serial number to 89  
  arr[5] = 89;
 
// c) Set the value of 3rd serial number to the addition of first two serial numbers.
  arr[3]= arr[0] + arr[1];

// d) Display the serial number on 2nd index  
  cout << "arr[2] = "<< arr[2]<<endl;
   
// e) Print the whole array
    for(i=0;i<8;++i)
        cout<<arr[i]<<" ";   

    cout<<endl;
    
return 0;
