3- Write a function pow (double base, int exp) to calculate integral powers of floating-point numbers. Arguments: The base of type double and the exponent of type int. Returns: The power baseexp of type double. For example, calling pow (2.5, 3) returns the value 2.53 = 2.5 * 2.5 * 2.5 = 15.625 This definition of the function pow( ) means overloading the standard function pow ( ), which is called with two double values. Test your function by reading one value each for the base and the exponent from the keyboard. Compare the result of your function with the result of the standard function. Hint: • The power x° is defined as 1.0 for a given number x. • The power x" is defined as (1/x)-" for a negative exponent n.

Mark the following statements as true or false: a. To use a predefined function in a program, you need to know only the name of the function and how to use it. (1) b. A value-returning function returns only one value. (2, 3) c. Parameters allow you to use different values each time the function is called. (2, 7, 9) d. When a return statement executes in a user-defined function, the function immediately exits. (3, 4) e. A value-returning function returns only integer values. (4) f. A variable name cannot be passed to a value parameter. (3, 6) g. If a C++ function does not use parameters, parentheses around the empty parameter list are still required. (2, 3, 6) h. In C + + , the names of the corresponding formal and actual parameters must be the same. (3, 4, 6) i. A function that changes the value of a reference parameter also changes the value of the actual parameter. (7) j. Whenever the value of a reference parameter changes, the value of the actual parameter changes. (7) k. In C++, function definitions can be nested; that is, the definition of one function can be enclosed in the body of another function. (9) l. Using global variables in a program is a better programming style than using local variables, because extra variables can be avoided. (10) m. In a program, global constants are as dangerous as global variables. (10) n. The memory for a static variable remains allocated between function calls. (11)
1. Square Flower You can have the turtle draw an interesting flower like sha pe by drawing n squares. Each n-square flower is drawn after turning the turtle by some number of degrees between each square. (see Figure 1 for an example) (a) Typel: A 5-square red flower. (b) A 15-square blue flower. Figure 1: Two types of n-square flowers Using the following implementation of draw square() function write a function na med draw flower() that takes a turtle, the number n of squares to draw, the side length and a color as parameters and draws an n-square flower by repeating the function draw square() n times.

Programming Language : R programming (R Studio) A twin prime is a prime that has a prime gap of two. Sometimes the term twin prime isused for a pair of twin primes. For example, the five twin prime pairs are (3, 5), (5, 7),(11, 13), (17, 19) and (29, 31). Write a function that returns the number of all twin primepairs between 1 and a given number n.

Assignment Write a program to calculate n! for a given number n and perform the simple calculator operations. The valid operations of the calculator are: + add - sub * mul I div The program must contain a function fact with one input parameter that returns the factorial of a number, a function add that performs the addition of two numbers, a function sub that performs the subtraction of two numbers, a function mul that performs the multiplication of two numbers, a function div that performs the division of two numbers. The program must also check for bad input data. Make sure when you pass parameters you pass the addresses (not the value). • All function return type must be of type void. • Take inputs in main function. • Pass the addresses of the operands and the address of the result to each function. Output must be displayed as follows: 1: Addition 2: Subtraction 3: Multiplication 4: Division 5: Factorial 6: Quit Enter the choice => 1 Enter two numbers => 2, 3 Sum => 5
LAB: User-Defined Functions: Miles to track laps One lap around a standard high-school running track is exactly 0.25 miles. Define a function named MilesToLaps that takes a float as a parameter, representing the number of miles, and returns a float that represents the number of laps.Then, write a main program that takes a number of miles as an input, calls function MilesToLaps() to calculate the number of laps, and outputs the number of laps. Ex: If the input is: 1.5 the output is: 6.0 Ex: If the input is: 2.2 the output is: 8.8 Your program should define and call a function: Function MilesToLaps(float userMiles) returns float userLaps Note: Remove all comments outside any functions before running the program.
Write a function that parses a decimal number into an octal number. The function header is as follows: int dec2Octal(const int& decimal) Write a test program that prompts the user to enter a decimal number, uses the dec2Octal function to parse it into an equivalent octal number and displays the octal number.

integer) Write a function that computes the sum of the digits in an integer. Use the following function header:def sumDigits(n):For example, sumDigits(234) returns 9 (Hint: Use the % operator to extract digits, and the // operator to remove the extracted digit. For instance, toextract 4 from 234, use 234 % 10 To remove 4 from 234, use 234 // 10 (=23) Use a loop to repeatedly extract and remove the digits until all the digits are extracted.) Write a test program that prompts the user to enter an integer and displays the sum of all its digits.
