***Microsoft Visual Studios (C++)*** Write a program that given two coordinate pairs and a third single coordinate will linearly interpolate or extrapolate the third second coordinate. For example, let's say at 50 degrees Celsius the length of a metal rod is 5.4 cm and at 60 degrees Celsius the length is 5.5cm. I can interpolate the length at 53 degrees Celsius by doing 5.4cm + 3*(.1/10)=5.43cm. Your program does not need to continuously run, but should prompt the user for two coordinate pairs, the third first coordinate and return the extrapolated or interpolated third second coordinate.
python: def shakespeare_position(role, section): """ Question 2 - Regex You are reading a Shakespeare play with your friends (as one frequently does) and are given a role. You want to know what line immediately precedes YOUR first line in a given section so that you are ready to go when it is your turn. Return this line as a string, excluding the character's name. Lines will always begin with the character's name followed by a ':' and end in a "." or a "?" Each line is separated by a single space. THIS MUST BE DONE IN ONE LINE.

Write two versions of each of the string-copy and string-concatenation functions in Fig. 8.14. The first version should use array indexing, and the second should use pointers and pointer arithmetic. in c programming language
Generate a constrained Regular Expression for the language that is described by the following: 1) all strings MUST begin with at least one 'a' character 2) all strings MUST end with EXACTLY one 'a' 3) between the 'a' characters are an unknown number of 'b', 'c', and 'd' characters. 4) the number of 'c' characters are at least one. 5) the number of 'b' characters is exactly the same as the number of 'd' characters.
A business law class of 25 students takes a midterm exam that has 100 true- or-false questions. The instructor, who is also a computer fanatic, wants to devise a program to obtain a printout with the student's name, score, and letter grade, according to the following schedule: 50 or below F 51 - 55 D 56 – 60 C- 61 - 65 66 – 70 C+ 71 - 75 B- 76 - 80 81 - 85 86 – 90 B B+ А- 91 - 95 A 96 – 100 A+ In addition, the instructor wants to include the total number of students scoring each of the 11 possible grades. How would you use the FORTRAN language to solve his problem?

Programing C First, you should ask how many passports will be issued.Then, ask for the first name, last name, address, passport ID and gender of each passport.Lastly, print out the information. Follow some guidelines when writing your code: You should have one structure definition with the following members:· FirstName: should be a character array, accepting at most 100 characters· LastName: should be a character array, accepting at most 100 characters· Address: should also be a char array, accepting at most 100 characters· PassportID: should be an integer· Gender: should be a single character You should at least have five functions (including main) in your code. You can have more if you want, but you should at least have five. I recommend the following functions · One function that scans the information of each passport.· One function that scans a character array. In my opinion, this is the most important one, since you will be able to re-use it every time you need to read a first…
A program in the C language that receives from the user an actual number up to 3 digits after the dot, It can be assumed that the number does not contain more than 3 digits after the dot. The program will separate it into a whole and an actual part. The number should be printed as an integer followed by a fraction, Pay attention to the accuracy of the actual numbers to handle a situation where there is an inaccuracy (like 2.3 Which appears as 2.299). Note: The MODF function must not be used, The things that are only allowed to be used are Types, operators and conditions, For example: The number 3.532 will be printed: 3 532/ 1000 The number 43.75 will be printed: 43 75/ 100 The number 84.5 will be printed: 84 5/ 10 The number 2.3 will be printed: 2 3/ 10 The number 85 will be printed: 85 0/ 10 The number 33 will be printed: 33 0/ 10

A:rV I TV sheet 2.pdf → Q1: A complex number x=(a + jb) contains two parts, a real part (a) and an imaginary part (b). Write a computer program using C++ to declare a data structure float_c to represent a complex number. The structure contains two type float members, real and imag, to represent real and imaginary parts respectively. Q2: Using the data structure in Q1, write for functions to perform the following: • add c( float_c x, float_e yl that returns the sum of the twc complex numbers (x+yl. • negative c float e x) that returns (-x). • conjugate et float c x) that returns (a -jb). Q3: Using the data structure in Q1, and Q2 write for functions to perform the following: subtract_c( float_c x, float_c y that returns the difference of the two complex numbers (x-V). • multiply c float c x, float c yi that returns the product of the two complex numbers (x"y)- • divide_c{ float_e x, tioat_c yi that returns the division result of the two complex numbers (x/y). divide e( float e x,…
Q No. 1: Write regular expressions and construct NFA for the following languages over the alphabet E ={a, b} a. Write a regular expression that contains at least two a's b. Write a regular expression that contains at least one a and one b c. Write a regular expression that contains exactly two a's d. All strings that do not end with 'aa' e. All strings that contain even number of a's f. All strings which do not contain the substring 'ab' g. All strings that contain odd number of a's and b's
3. A palindrome is a sentence that contains the same sequence of letters read-ing it either forwards or backwards. A classic example is "Able was I, ere I saw Elba." Write a recursive function that detects whether a string is a palindrome. The basic idea is to check that the first and last letters of the string are the same letter; if they are, then the entire string is a palindrome if everything between those letters is a palindrome. There are a couple of special cases to check for. If either the first or last character of the string is not a letter, you can check to see if the rest of the string is a palindrome with that character removed. Also, when you compare letters, make sure that you do it in a case-insensitive way. Use your function in a program that prompts a user for a phrase and then tells whether or not it is a palindrome. Here's another classic for testing: "A man, a plan, a canal, Panama!"
