CIS 150 Arrays lab

Objectives

Declare an array
Initialize an array
Access elements of an array
Use repetition to process all elements of an array

Requirements

Modify the supplied program (arrayLab.cpp) to make it work properly.

Program to be modified

#include <iostream>
using namespace std;

int main() {
    // 1. Declare an array of type integer named iNum and initialize
    //    it with the values 2, 4, 6, 8, 10.
    
    // 2. Write a statement to output the third element of array iNum
    //    followed by a newline.
    
    // 3. Write a statement to store the value 12 in the last
    //    element of array iNum.
    
    // 4. Declare an integer variable named index and set that variable
    //    to the value needed to use it as an index to access the second
    //    element of the array iNum.

    // 5. Use the variable "index" as a subscript to display the 
    //    second value of the iNum array.
    
    // 6. Write a "while" loop using index that will output all of the
    //    elements of the array iNum. The values should be separated by
    //    a space and a newline should be output at the end.

    // 7. Write a function that takes three arguments. The first is the
    //    name of an integer array, the second is an integer that specifies
    //    a position in the array, and the third is an integer that will
    //    be stored in the array. This function returns nothing.
    
    // 8. Write the prototype for the function above and place it before main()
    
    // 9. Call the function you wrote and send it the iNum array, 1, and 21 as
    //    the arguments, which should store 21 in the second element of the array.
    
    //10. Write a "for" loop using index that will output all of the elements
    //    of the array iNum. The values should be separated by a space and
    //    a newline should be output at the end.
    
    cout << "Press enter to continue...";
    cin.get();
    return 0;
}
