Array
 An array is used to process a collection of data all of
which is of the same type, such as a list of temperatures
or a list of names.

Program 1
 Write a C++ program that stores ‘a’, ‘b’, ‘c’ in an array
and print the values of the array using for loop.
Solution to Program 1
#include <iostream>
using namespace std;
int main()
{
char symbol[3] = {'a', 'b', 'c'};
for (int index = 0; index < 3; index++)
cout << symbol[index];
}
Program 2
 Write a C++ program that stores numbers from zero to
nine in an array using a for loop and print the values of
the array using a different for loop.
Solution to Program 2
#include <iostream>
using namespace std;
int main()
{
int i, temp[10];
for (i = 0; i < 10; i++)
temp[i] = i;
for (i = 0; i < 10; i++)
cout << temp[i] << " ";
}
Program 3
 Write a C++ program that stores numbers from zero to
nine in an array and print the values of the array using
only one for loop.
Solution to Program 3
#include <iostream>
using namespace std;
int main()
{
int i, temp[10];
for (i = 0; i < 10; i++)
{
temp[i] = i;
cout << temp[i] << " ";
}
}
Program 4
 Write a C++ program that stores the following values
in an array and prints the total and average.
23, 6, 47, 35, 2, 14
Solution to Program 4
#include <iostream>
using namespace std;
int main()
{
int sample_array[]={23, 6, 47, 35, 2, 14};
int total=0;
for (int index = 0; index <= 6; index++)
total=total+sample_array[index];
cout<<"total is "<< total<<" the average is "<<total/6;
}
Program 5
 Write a C++ program that stores the following values
in an array and print the first five values in the array
using a for loop.
2, 4, 6, 8, 10, 1, 3, 5, 7, 9
Program 6
 Write a C++ program that accepts five numbers from
the user and store them in an array and prints out the
maximum number. Note use for loop.
Program 7
 Write a C++ program that stores the following letters
in an array and prints out them as one word. Note use
for loop to print.
‘h’, ‘e’, ‘l’, ‘l’, ‘o’
Program 8
 Write a C++ program that prints the following output
using an array and for loop.
