The document discusses C++ programs to find the maximum and minimum values from arrays and compare two or three values using conditional operators. It includes the code and output for programs that find the maximum and minimum values from arrays using classes, and programs that compare two or three values entered by the user to find the greatest value using conditional operators both with and without classes.

3. OUTPUT
Enter value of a: 45
Enter value of b: 56
Original value of a is:45
Original value of b is:56
After Swapping
New value of a is:56
New value of b is:45

4. Output
Value of a is: 10
Value of b is: 15
After swapping
New Value of a is: 15
New value of b is: 10

5. OUTPUT
Enter value of a: 45
Enter value of b: 56
Original value of a is:45
