What are the 3 types of numbers in Python?
Python includes three numeric types to represent numbers: integers, float, and complex number.
What is %d in printf?
printf() function in C language: We use printf() function with %d format specifier to display the value of an integer variable. Similarly %c is used to display character, %f for float variable, %s for string variable, %lf for double and %x for hexadecimal variable.
What is difference between i ++ and ++ i in Java?
They both increment the number. ++i is equivalent to i = i + 1 . … Both increment the number, but ++i increments the number before the current expression is evaluted, whereas i++ increments the number after the expression is evaluated.
What is the difference between N and R in Java?
\n is a line feed (LF) character, character code 10. \r is a carriage return (CR) character, character code 13. … On Windows, for instance, lines in text files are terminated using CR followed immediately by LF (e.g., CRLF). On Unix systems and their derivatives, only LF is used.

What does %d mean in Java?
There are many converters, flags, and specifiers, which are documented in java.util.Formatter. Here is a basic example: int i = 461012; System.out.format(“The value of i is: %d%n”, i); The %d specifies that the single variable is a decimal integer. The %n is a platform-independent newline character.
What is r in string?
What does \r do in Java?
\r (carriage return) is what it sounds like if you’re familiar with old-fashioned manual typewriters: It moves the “carriage” (the roll the paper is fed through) back to the beginning of the line.
What does \t do in Python?
In Python strings, the backslash “\” is a special character, also called the “escape” character. It is used in representing certain whitespace characters: “\t” is a tab, “\n” is a newline, and “\r” is a carriage return. Conversely, prefixing a special character with “\” turns it into an ordinary character.
