How do you swap digits of numbers?

Algorithm to swap first and last digit of a number:

  1. Ask the user to enter an integer number. Suppose n = 12345, where n is an integer variable.
  2. To find the last digit of a number, we use modulo operator %.
  3. Find the first digit with the help of mathematical operation.
  4. Use below logic to swap first and the last digit.

How do I swap two numbers using Bitwise Operators?

Java Program to Swap Two Numbers Using Bitwise Operator

  1. Find the binary equivalent of given variables, say X and Y.
  2. Find X^Y and store it in x, i.e. X = X ^ Y.
  3. Again, find X^Y and store it in Y, i.e. Y = X ^ Y.
  4. Find X^Y and store it in X, i.e. X = X ^ Y.
  5. The numbers are swapped.

  8. swap(&a,&b);

What is a function in C program?

A function is a group of statements that together perform a task. Every C program has at least one function, which is main(), and all the most trivial programs can define additional functions. You can divide up your code into separate functions. A function definition provides the actual body of the function.
