This means b = 15 - 10. So, b = 5 now. Again, we use the code a = a - b. This means a = 15 - 5. So finally, a = 10. Hence, the numbers have been swapped. Note: We can use multiplication and division instead of addition and subtraction. However, this won't work if one of the numbers is 0.

A linked list is a linear data structure that includes a series of connected nodes. Here, each node stores the data and the address of the next node. For example, Linked list Data Structure.

C++ Program to Check Whether Number is Even or Odd. Example explained. Statement 1 sets a variable before the loop starts (int i = 0). Statement 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. Statement 3 increases a value (i++) each time the code block in the loop has been executed.C++ Code Example: simple calculator. This is a simple calculator program that asks the user to enter an arithmetic operation (+, -, *, /) and two numbers. It then performs the requested operation and displays the result.
