(1.13) A binary number is passed as a parameter to a function in the form of a binary string. Write the function such that it also returns a string which is the one's complement of the binary number passed as the parameter.
#17a Simple Statistics (not in textbook) Generate a STL array or vector of 1000 floating point numbers in the range 0 to 1. Compute the mean, median, and standard deviation of these. You may use function objects and lambda expressions, and the STL algorithms for_each, accumulate, and sort. You may not use any of the built-in looping constructs while, do-while or for. Also you may not create and use any ordinary c++ functions. Hint: The following code can be used to populate your random array named arr auto arr_store = [](float& v) { v = rand()/float(RAND_MAX); }; for_each(arr.begin(),arr.end(),arr_store); Warning, You may need to know some details about lambda expressions that are not covered in the textbook. These will be covered in the weekly lecture and in a sample program in Sakai resources. Note: The theoretical value of the standard deviation for large N is sqrt(1.0/12) which about 0.289. You should be getting a value fairly close to this.

(Greatest Common Divisor) Given two integers x and recursive definition determines the greatest common divisor of x and y, written gcd(x,y): Y, if y = 0 gcd(x, y) = %3D gcd(y, x%y) if yチ0 Note: In this definition, % is the mod operator. write a recursive function, gcd, that takes as parameters two integers and returns the greatest common divisor of the numbers. Also, write a pro- gram to test your function.

9.10 C++ Complete main() to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. Use the substr() function to parse the string and extract the date. The input ends with -1 on a line alone. Output each correct date as: 3-1-1990. Ex: If the input is: March 1, 1990 April 2 1995 7/15/20 December 13, 2003 -1 then the output is: 3-1-1990 12-13-2003

If the month string is valid, an integer in the range 1 to 12 inclusive is returned, otherwise 0 is returned. Ex: GetMonthAsInt("February") returns 2 and GetMonthAsInt("7/15/20") returns 0.
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 * c++ program 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. The power 0" where n > 0 will always yield 0.0 . The power 0" is not defined for n < 0. In this case, your function should return the value 0. Don't forget the negative exponent
