This page has 20 examples of C++ programs with …Encapsulation. The meaning of Encapsulation, is to make sure that "sensitive" data is hidden from users. To achieve this, you must declare class variables/attributes as private (cannot be accessed from outside the class). If you want others to read or modify the value of a private member, you can provide public get and set methods.endl Manipulator. " endl " is the line feed operator in C++. It acts as a stream manipulator whose purpose is to feed the entire line and then point the cursor to the beginning of the next line. You can also use " \n " (escape sequence) instead of " endl " …It is because the sizeof () operator returns the size of a type in bytes. You learned from the Data Types chapter that an int type is usually 4 bytes, so from the example above, 4 x 5 (4 bytes x 5 elements) = 20 bytes. To find out how many elements an array has, you have to divide the size of the array by the size of the data type it contains:

Example explained. Expression 1 sets a variable before the loop starts (int i = 0). Expression 2 defines the condition for the loop to run (i must be less than 5). If the condition is true, the loop will start over again, if it is false, the loop will end. Expression 3 increases a value (i++) each time the code block in the loop has been executed.

This allows us to perform …

In the example above, time (22) is greater than 10, so the first condition is false. The next condition, in the else if statement, is also false, so we move on to the else condition since condition1 and condition2 is both false - and print to the screen "Good evening".

An Array is a collection of data of the same data type, stored at a contiguous memory location. Indexing of an array starts from 0. It means the first element is stored at the 0th index, the second at 1st, and so on. Elements of an array can be accessed using their indices. C ignores white space. But we use it to make the code more readable. Line 3: Another thing that always appear in a C program is main (). This is called a function. Any code inside its curly brackets {} will be executed.
