Input Stream

Activity #2

Problem 1:

Write a program to require the user to input a string. Process the string by counting the total number of vowels and consonants in the string. For additional reference, please visit http://www.tutorialspoint.com/java/java_strings.htm , http://bit.ly/28TBVbB


VALIDATION

Sample Output #1:
Enter a string: Chance favors the prepared minds.

Vowels: 9
Consonants: 19

Sample Output #2:
Enter a string: The quieter you become, the more you are able to hear!

Vowels: 22
Consonants: 20

Sample Output #3:
Enter a string: Swing your rope down low.

Vowels: 7
Consonants: 13

------------------------------------------------------------------------------------------------------
Problem 2:

Write a program to require a string input from the keyboard. Using a loop structure, read the string backwards and display the result.

Sample Output #1:
Enter a string: Government
tnemnrevoG


Sample Output #2:
Enter a string: Aliens
sneilA

Sample Output #3:
Enter a string: Absurd
drusbA

FIND THE SECOND LARGEST NUMBER IN THE ARRAY

/**
* find the second largest integer in an array.
* @param ia an array of integers
* @return the second largest number in ia
*/
private static int secondLargest(int[] ia)
{
int first_largest=0;
int second_largest=0;

//find the first largest
for (int i=0; i<ia.length; i++){
if (ia[i] > first_largest)//determine first the first largest so that we can identify the second largest
first_largest=ia[i];

}
//find the second largest
for (int i=0; i<ia.length; i++){
if (ia[i] > second_largest && ia[i]<first_largest) //check if it is the second largest
second_largest=ia[i];

}

return second_largest;
} //secondLargest

C++ Practice Exercise

Write a C++ program that will display the calculator menu.

The program will prompt the user to choose the operation choice (from 1 to 5). Then it should ask the user to input two integer values

for the calculation.

See the sample below.


MENU
  1. Add
  2. Subtract
  3. Multiply
  4. Divide
  5. Modulus

Enter your choice: 1

Enter your two numbers: 12 15

Result: 27
 
Continue? y




 
The program also asks the user to decide whether he/she wants to continue the operation. If he/she input ‘y’, the program will prompt

the user to choose the operation gain. Otherwise, the program will terminate.
