Write your own definition for the function absfun( )
which receives real number x as an argument and returns its absolute value (i.e. abs(x)=|x|).
Use this function in a program that reads numbers from the keyboard and prints their absolute values.
[Don’t use math library]
Sample Run
Enter x :-3
Output: abs(-3) = 3.00

Please help me solve this problem with kind explanations :)
We are running programs on a machine where values of type int have a 32-bit two's complement representation. Values of type float use the 32-bit IEEE format, and values of type double use the 64-bit IEEE format.
We generate arbitrary integer values x, y, and z, and convert them to values of type double as follow:
/* Create some arbitrary values */
int x = random();
int y = random();
int z = random();
/* Convert to double */
double dx = (double) x;
double dy = (double) y;
double dz = (double) z;
For each of the following C expressions, you are to indicate whether or not the expression always yields 1. If it always yields 1, describe the underlying mathematical principles. Otherwise, give an example of arguments that make it yield 0. Note that you cannot use an IA32 machine running GCC to test your answers, since it would use the 80-bit extended-precision representation for both float and double.
A. (double)(float) x == dx
B. dx…
We are familiar with word count features of word processors such as found in MS-Word. These will report the number of words and
characters in a document. We would like to write a function that we can eventually use to analyze a python program. That is write a function
that will return the number of non-white space characters, the number of variable/function names used in the program, and the number of
characters used in the variable/function names.
The rules for Python names are:
• A variable name must start with a letter or the underscore character.
• A variable name cannot start with a number.
• A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _)
• Variable names are case-sensitive (age, Age and AGE are three different variables)
Write a function python_word_count which when passed a string containing python code will return a tuple of total number of non-white
space characters, number of characters found in the Python names, and the number of…

It has asked you to write a program that will encrypt the data so that it may be transmitted more securely. All the data transmitted is 4 digit integers. Your program should read a four digit integer entered by the user and calls a function encrypt which takes four digits as arguments and encrypt it as follows . Replace each digit with the result of adding 4 to the digit and getting the remainder after dividing the new value by 10. . Calls another function swap which swaps the first digit with the third, and second digit with the fourth using pass by reference. Then it prints the encrypted integer.arrow_forwardWrite a C++ program that takes an char array of size twenty. Take input a sorted array from the user.
