4. Write a program called MathExpress that evaluates basic mathematical expressions such as 2+15.1 and 3.1416* 4.5 provided as input by the user. The program accepts as input a string expression consisting of a number, followed by an arithmetic operator, followed by another number, such as "2+15.1". (operators that are allowed are: +, -, *, and /). Then the program scans the expression in order to compute and print its value on-screen. Sample output: Enter math expression: 2+15.1 Result: 17.1

1. Write a Python regex pattern that matches a valid email address, assuming that an email address consists of a username, followed by the "@" symbol, followed by a domain name, which in turn consists of one or more subdomains separated by dots, and ending with a top-level domain (e.g., .com, .org, .edu, etc.). 2. Using the re.findall() function in Python, write a Python code snippet that takes the text string and the regex pattern from Q4 and returns a list of all the email addresses found in the string. 3. Suppose you want to modify the regex pattern from Q4 to also match email addresses that contain hyphens ("-") in the username and/or domain name. What changes would you make to the pattern, and why? 4. Using the modified regex pattern from Q6, write a Python code snippet that takes the text string and the modified regex pattern, and returns a list of all the email addresses found in the string. Note: You can assume that the text string contains valid email addresses separated by…

In C++, create a program which will read a phrase from the user and create a framed version of it for printing. For example, the phrase "hello world"would result in: ********* * hello * * world * ********* Whereas the phrase "the sky is falling"might be: *********** * the * * sky * * is * * falling * *********** Or: *********** * the * * sky * * is * * falling * *********** Or even: *********** * the * * sky * * is * * falling * *********** Depending on whether or not the user asked for left, centered, or right justification — respectively — of the phrase's words within the frame. Note how the frame exactly fits the phrase based on the longest word within. Neat, eh? The phrase "O | -+- | /-\"when centered would become: ******* * O * * | * * -+- * * | * * /-\ * ******* (Okay, so it's a sad excuse for a stick figure, but hey! I've never claimed to be a great good decent…
Program72.java See Section 7.13 and watch the Command Line Arguments (2:08) video (image of the video below). Then, write a program that takes two double command line arguments representing the sides of a rectangle. The program should then call a void function that reports the area of the rectangle accurate to three decimal places.
C++ Write a language segment to read the speed of a vehicleand to output the fine that they deserve based of speed $0.00 for a speed <= 50 mph; $25.00 for a speed such that 50 < speed <= 70; $40.00 for a speed such that 70 < peed <= 80; and $60.00 for a speed such that speed > 80.
3.19 In Java Write a program with total change amount in pennies as an integer input, and output the change using the fewest coins, one coin type per line. The coin types are Dollars, Quarters, Dimes, Nickels, and Pennies. Use singular and plural coin names as appropriate, like 1 Penny vs. 2 Pennies. Ex: If the input is: 0 the output is: No change Ex: If the input is: 45 the output is: 1 Quarter 2 Dimes
java please, 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 substring() method 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
Using c++, write a program that reads students’ names followed by their test scores. The program should output each student’s name followed by the test scores and the relevant grade. It should also find and print the highest test score and the name of the students having the highest test score. Student data should be stored in a class variable of type studentType, which has four private components: studentFName and studentLName of type string, testScore of type int (testScore is between 0 and 100), and grade of type char. Suppose that the class has 20 students. Use an array of 20 components of type studentType. Your program must contain at least the following functions: A function to read the students’ data into the array. A function to assign the relevant grade to each student. A function to find the highest test score. A function to print the names of the students having the highest test score. Your program must output each student’s name in this form: last name followed by…
In C++ 2.12 LAB: Hypotenuse Given two numbers that represent the lengths of a right triangle's legs (sides adjacent to the right angle), output the length of the third side (i.e. hypotenuse) with two digits after the decimal point. Output each floating-point value with two digits after the decimal point, which can be achieved by executingcout << fixed << setprecision(2); once before all other cout statements. Ex: If the input is: 3.0 4.0 the output is: Hypotenuse: 5.00
