Write the code in python programming for the below problem. Introduction One useful data point in detecting fraud is the account history of a customer. For an account, we receive notification of purchases and, sometimes, reports of fraud. Typically, a prior report of fraud for an account would increase the perceived risk of fraud on future transactions. Similarly, a history of non-fraudulent purchases for an account would decrease the risk of fraud. A credit card holder has 90 days to report any fraudulent transactions with the card. So if an account has purchases over 90 days old and no reports of fraud, we assume that these older purchases were not-fraudulent. Problem Description The purpose of this programming problem is to determine the status of a customer account history at the time a new purchase is made. The input is a sequence of customer account events, in chronological order. Each event has three fields, all of which are of string type ,, For example:…

You are expected to use python Object-Oriented programming concepts to design and implement a system in python for building a scientific calculator which inherits its basic operations from a standard calculator. The standard calculator can perform two types of operations: an addition and a subtraction The standard calculator is capable of inputting only two integers. But the scientific calculators can also interpret decimal values. The scientific calculator is capable of four operations: addition, subtraction, cosine and sine of values. The scientific calculator can accept multiple values for the addition operation. After performing an addition, the scientific calculator will send the final result to a database. (You are not expected to write the codes for the database connection and the queries. You are expected to only show how you can use your scientific calculator object to pass messages to a database object) Create 100 objects for your scientific calculator to enable…
Write these codes in c language please. Thank you in advance 1. Define a function PrintFeetInchShort(), with int parameters numFeet and numInches, that prints using ' and " shorthand. End with a newline. Remember that "\n" in a string literal starts a new line. Ex: PrintFeetInchShort(5, 8) prints:5' 8" 2. Write a function so that the main() code below can be replaced by the simpler code that calls function MphAndMinutesToMiles(). Original main(): int main(void) { double milesPerHour; double minutesTraveled; double hoursTraveled; double milesTraveled; scanf("%lf", &milesPerHour); scanf("%lf", &minutesTraveled); hoursTraveled = minutesTraveled / 60.0; milesTraveled = hoursTraveled * milesPerHour; printf("Miles: %lf\n", milesTraveled); return 0; } 3. Define stubs for the functions called by the below main(). Each stub should print "FIXME: Finish FunctionName()" followed by a newline, and should return -1. Example output:FIXME: Finish GetUserNum() FIXME: Finish GetUserNum()…
write a python program 9. You are a class teacher at a kindergarten school. As a task, you asked your students to write a paragraph. Unfortunately, you notice that most of the students did not use capital letters correctly. Your task is to write a function which takes a string as its only parameter and returns a new copy of the string that has been correctly capitalized. Your function should: Capitalize the first letter in the string Capitalize the first letter after a full-stop, exclamation mark or question mark • Capitalize the word “i" if it is in lowercase. Summary: You have to write a function that reads a string from the user and capitalizes. The string is then returned and displayed. Sample Input ('my favourite animal is a dog. a dog has sharp teeth so that it can eat flesh very easily. do you know my pet dog's name? i love my pet very much.') Sample Output My favourite animal is a dog. A dog has sharp teeth so that it can eat flesh very easily. Do you know my pet dog's name? I…

please code in python MCQ are a very popular form of assessment because they can be automatically graded…and the students can choose an answer at random if they don’t know.The goal of this exercise is to write a function scoreMCQ(attempt, correct), where attempt is a string that contains the answers of the student and correct is a string with the correct answers.The function should return the number of correct answers.Check first that both strings have the same length, otherwise raise an exception.If both strings are empty the score should be 0 of course.To test your code, you can copy paste the following assert statements as your main function:assert(scoreMCQ("","")==0), "First test failed"assert(scoreMCQ("TFTF","TTTT")==2), "Second test failed"assert(scoreMCQ("TTTT","TTTT")==4), "Third test failed"assert(scoreMCQ("CCCC","ABCD")==1), "Fourth test failed"print("All tests succesfull")

Write a program in C that, given two points on a two-dimensional graph, outputs a message (string) if the line that connects them is horizontal or vertical, or if the slope is positive or negative.What would you modify or adjust in your code if we move from a 2D cartesian system to a 3D dimensional cartesian system?You need to take into consideration if the system is 3D and therefore you need to ask the user to insert X, Y , and Z.
