- (Data processing) Your professor has asked you to write a C++ program that determines grades at the end of the semester. For each student, identified by an integer number between 1 and 60, four exam grades must be kept, and two final grade averages must be computed. The first grade average is simply the average of all four grades. The second grade average is computed by weighting the four grades as follows: The first grade gets a weight of 0.2, the second grade gets a weight of 0.3, the third grade gets a weight of 0.3, and the fourth grade gets a weight of 0.2. That is, the final grade is computed as follows: 0.2grade1+0.3grade2+0.3grade3+0.2grade4 Using this information, construct a 60-by-7 two-dimensional array, in which the first column is used for the student number, the next four columns for the grades, and the last two columns for the computed final grades. The program’s output should be a display of the data in the completed array. For testing purposes, the professor has provided the following data:THIS IS FOR C++ ONLY Part 2b: Password Verification A secure password is critically important in today's world. Organizations typically have stringent requirements to ensure a password is complex enough so as not to be easily hacked. Write a program that will accept as input a potential password and determine whether or not it is valid in meeting the following criteria: at least eight characters long at least one uppercase letter at least one lowercase letter at least one digit at least one special character (you can determine what is acceptable) If the password is valid, ask the user to enter it again. If it matches, indicate the password has been accepted. If the password does not meet any of the above criteria, indicate which it does not meet.Define the function: int power (int base, int exp) {/*It accepts the arguments for base and exponent and returns power. The algorithm is to repeatedly multiply the value of the base to how many times the value of exponent. Test the function inside main(). Write the complete C program. */} For example: Intput.

A regular ticket usually costs $3.99 and a stu- dent ticket costs only $2.99. If the total number of tickets being ordered (including both students and regular tickets) is at least 10, then a 10% discount is applied to the order. However, if it is a holiday, then the at-least-ten group discount is only 5% (not 10%). Write a program that takes three lines of input: the number of reg- ular tickets, the number of student tickets, and an integer indicating whether it is a holiday (1) or not (0). It prints a float giving the total cost. Be sure to define and use constants for REGULAR TICKET PRICE and STUDENT TICKET PRICE. Write your program in a file named tickets.py.Python Answer Required: A Rajesh teaches a cooking class. The course is attended by NN students, numbered 11 to NN. The cook must participate in the presence before each class, i.e. call out the names of the students one by one and indicate which students are present. Each student has a first and last name. To save time, Rajesh only wants to call up students' first names. However, if there are multiple students with the same first name, the Rajesh must call out the full names (first and last names) of all those students. For any student who does not share a first name with any other student, the cook can still only call that student's first name. Help the Rajesh decide for each student whether to call that student's full name or just their first name. Input 1 1 hasan jaddouh Output hasan
- C++ Given an integer num, return the number of steps to reduce it to zero. In one step, if the current number is even, you have to divide it by 2, otherwise, you have to subtract 1 from it. Example 1: Input: num = 14 Output: 6 Explanation: Step 1) 14 is even; divide by 2 and obtain 7. Step 2) 7 is odd; subtract 1 and obtain 6. Step 3) 6 is even; divide by 2 and obtain 3. Step 4) 3 is odd; subtract 1 and obtain 2. Step 5) 2 is even; divide by 2 and obtain 1. Step 6) 1 is odd; subtract 1 and obtain 0. Example 2: Input: num = 8 Output: 4 Explanation: Step 1) 8 is even; divide by 2 and obtain 4. Step 2) 4 is even; divide by 2 and obtain 2. Step 3) 2 is even; divide by 2 and obtain 1. Step 4) 1 is odd; subtract 1 and obtain 0. Example 3: Input: num = 123 Output: 12COSC 1336 – Programming Fundamentals IProgram 8 – Simple Functions Write in Python Program: The quadratic formula is used to solve a very specific type of equation, called a quadratic equation. These equations are usually written in the following form:ax2 + bx + c = 0The Quadratic Formula x = ( -b ± √( b^2 - 4ac ) ) / ( 2a ) Where a, b, and c are constants with a ≠ 0. (If a = 0, the equation is a linear equation.)The discriminant is the part of the formula in the square root. If the value of the discriminant is zero then the equation has a single real root. If the value of the discriminant is positive then the equation has two real roots. If the value of the discriminant is negative, then the equation has two complex roots.Write a program that finds the roots of the quadratic equation using the Quadratic Formula. Write a function named discriminant in the file, Disc.py, to calculate and return the discriminant of the formula. Let the main function call the discriminant function and…Code in C++ Language STRING FLIP ALPHABET One of the simplest cryptography technique is to invert the characters such that the first character of the alphabet will be replaced to the last character, the second character be replaced to the second to the last, and so on. So all A's are turned into Z's, B to Y, C to X, and so on until X to C, Y to B, and Z to A. In a similar fashion, numeric characters will also be inverted such that 0 will become 9, 1 to 8, 2 to 7 and so on until 7 to 2, 8 to 1, and 9 to 0. Given a string composed of uppercase and lowercase letters, numbers, and spaces, your task is to invert them. You also must keep the case of the letters as is. Input: A string composed of uppercase and lowercase letters, numbers, and spaces.
