4. Write a function called oddLessEven that returns the sum of the odd valued digits minus the sum of the even valued digits in a positive integer parameter. For example, a program that uses the function oddLessEven follows. (Submit a complete C++ program that contains the main function below and your oddLessEven function in a single file.) int main() { cout << oddLessEven(23) << endl; // prints 1 cout << oddLessEven(1234) << endl; // prints -2 cout << oddLessEven(777) << endl; // prints 21 return 0;

- 2. Write a complete C program that inputs marks of a student in 5 courses using any loop and writes these marks into an output file named myElements.txt. After that, it reads scores from myElements.txt and computes the grades based on the table below using a programmer-defined function char computeGrade(double score), and displays the grades on screen. - please, write the c program code and include comments on your code, contents of the file myElements.txt , and sample output. Thank you so much.I need help in creating a C function that will read a specific line from a text file in C based on the randomly generated number ranging from 1 to 50. The function would have the parameter of the text file and would return the string that the specific line of the text file contains. Note(the text file only contains characters , sentences and no numbers) Restrictions : Cant use break, exit(), break , continue,global variables. Only allowed to use stdio.h and string.h For instance if the random number is 4 then the function would return the 4th line of the particular text file.Problem 2Write a program called p2.py that contains a function called less_than_age() that takesa string filename and an integer x as parameters. You can assume that this file containsa list of comma-separated animal names and their ages, similar to the content in thesample file above. This function should store the names of all the animals with age lessthan x in a list and return the list.Again, test your function inside main().Sample output:>>> result = less_than_age(“samplefile_t9.txt”, 4)>>> print(result)[“wombat”, “koala”, “dingo”, “kookaburra”]
- I need help in creating a C function that will read a specific line from a text file in C based on the randomly generated number ranging from 1 to 50(have to use rand() ). The function would have the parameter of the text file and would return the string that the specific line of the text file contains. Restrictions : Cant use break, exit(), break , continue,global variables. Only allowed to use stdio.h and string.h For instance if the random number is 4 then the function would return the 4th line of the particular text file.Write a function that displays all the numbers between two integers in n lines, that are divisible by 5 or 7 (not by both). So, the function should take as parameters the minimum and maximum of integer numbers and n. If no values are passed to them, this function should display the numbers between 1 and 100 in 10 lines. Write a test program to test your function. *Output of the numbers should be formatted well in C++-Write a C++ program with the following functions, with the correct number of arguments for each function, as well as any other functions used in class. void fillUpArray ( argument1, argument2) This function should read in a text file called "theVillagers.txt" (You may download it on Canvas). "theVillagers.txt" is a text file of numbers in ascending order, ranging anywhere from 1 to 2500, nonrepeating. Each number is separated by a new line character. The very first number in the text file is a number that refers to how many entries are in the rest of the text file. This function should populate an array with all the remaining entries in the text file, but it should NOT declare any arrays itself and it should not reference any global variables. void getInput(argument1, argument2) This function should read in a text file of the user's choosing into a given array. It should discard excess input. You may assume that there are always 2000 entries in this text file being entered. void…
- Write a c++ program that takes a date in the following format: December 24th, 2021 and extracts the day, month, and year as 3 integers. Do not use string stream. Use a beginner level code. Your program should have the following functions: (a) WriteafunctiongetDatethatpromptsausertoenteradateasastringandreturns it. (b) Write a function extract that takes as its parameter a date and returns the day, month, and year as 3 integers.use the function isdigit(c) that returns true if c is a digit character and false if otherwise. (c) Write a function convertDigits that takes as its parameter a string of digits and converts it to an int.(to convert a digit character to a digit number use static_cast<Int> ('D') - static_cast<Int>('0') where d is 0,1,...,9) (d) Write a function convertMonths that takes as its parameter a month as a string and returns a corresponding number from 1 to 12 (1 for January, . . . , 12 for Decem- ber).7. Write a function password_check() that takes as input two stringsnewpassword and oldpassword, and that accepts the new password (i.e., returnsTrue) if newpassword is different from oldpassword and newpassword is atleast 6 letters long. If the new password fails the check, your functions should returnFalse.>>> password_check('E10-s2ff', 'E10.s2ff')True>>> password_check('E10sf', 'E10.s2ff')False>>> password_check('E10-s2ff', 'E10-s2ff')False(Extra Credit) For extra credit, extend your password function so that it also checks thatthe new password contains a digit.>>> password_check('E10-s2ff', 'E10.s2ff') True>>> password_check('Eej-sdff', 'E10.s2ff')False1. Write a function which takes one parameter int num, and prints out a countdown timer with minutes and seconds separated by a colon (:). It should print out one line for each second elapsed and then pause one second before printing out the next line. A few things to note: - You can assume that calling the function usleep(1000000) makes the program pause for one second - It should count down from num minutes:zero seconds to zero minutes:zero seconds - Your function must have the following signature: void timer(int num) You do not need to demonstrate calling this function from main(). You don't need to format the output nicely; the below is acceptable output for calling this function when minutes is 10: 10:0 9:59 9:58 … 9:1 9:0 8:59 8:58 … 0:2 0:1 0:0
- In this lab, you complete a partially written C++ program that includes two functions that require a single parameter. The program continuously prompts the user for an integer until the user enters 0. The program then passes the value to a function that computes the sum of all the whole numbers from 1 up to and including the entered number. Next, the program passes the value to another function that computes the product of all the whole numbers up to and including the entered number. The source code file provided for this lab includes the necessary variable declarations and the input statement. Comments are included in the file to help you write the remainder of the program. #include <iostream> #include <string> void sums(int); void products(int); using namespace std; int main() { double number; cout << "Enter a positive integer or 0 to quit: "; cin >> number; while(number != 0) { // Call sums function…Write a program in C Write two functions product1()andproduct2( )that can multiply two integers and return the result. Function product1()takes only two parameters (n1)and (n2)which are both input parameters. The second function product2( )takes an output parameter (p)in addition to those two input parameters.Write a program that opens a text file "integers.txt" to read two integers and calls the two functions product1( )and product2( )to test that they are working properly.How do I create a function in C++ that takes in a file name, ie. data.txt, on input and reads the data contained in the file and prints to screen the most frequently occurring integer in the file. Also, if two or more of the most frequently occurring integers occur equally often, it should return the largest.
