- (Numerical) Write a program that tests the effectiveness of the rand() library function. Start by initializing 10 counters to 0, and then generate a large number of pseudorandom integers between 0 and 9. Each time a 0 occurs, increment the variable you have designated as the zero counter; when a 1 occurs, increment the counter variable that’s keeping count of the 1s that occur; and so on. Finally, display the number of 0s, 1s, 2s, and so on that occurred and the percentage of the time they occurred.Write a C program that takes a command line argument of a number that you need to calculate the factorialvalue of.

- C++ Programming: Write a recursive function, sumDigits, that takes an integer as a parameter and returns the sum of the digits of the integer. Also, write a program to test your function. Your program should prompt the user for an integer and output the results to the console.Write a complete C++ program that asks the user to input information for at least 10 students. Use structure for the information below: Name of the student, Matric No, Course No, Obtained Marks The program should then display the information based upon marks in ascending and descending order. To solve ascending and descending order the program should have two functions that have an array of structure as a parameter and the functions should be called from the main function.C++ Write a program that uses a recursive function to convert a number in decimal to base 8 or base 16. Your program should prompt the user for an integer and then for either 8 for base 8 conversion or 16 for base 16 conversion and output the conversion to the console.
- Task using C language One common way of verifying if the data integrity of a file was preserved during a copy or transmission is to verify if the checksum matches. The checksum is a small piece of data computed from the original data. Your task is to compute a recursive function that maps an integer into a single digit to be used as checksum. Given an input integer in the range from 0 to 1012, the checksum is the sum of the digits of the input number. While the resulting sum has multiple digits, the checksum will be the sum of its digits instead. For instance: if the input is 34, the checksum is 7 (3+4); if the input is 99, the sum of its digits is 18 (9+9), so the checksum is 9 (1+8); if the input is 99999999999, the sum of its digits is 99 (9+9+9+9+9+9+9+9+9+9+9), whose sum of digits is 18 (9+9), so the checksum is 9 (1+8). Requirements Follow the format of the examples below. Make sure your variables and parameters have the correct data types. You must implement a recursive…Write a complete C++ program that asks the user to input information for at least 10 students.

- Using a pointer as the return value is considered a poor practise in C. For example, how does dynamic memory allow us to return an object pointer from a function safely?Write a C++ program to facilitate the usage of several string-handling functions. The program should present a menu for the choices available. The options might be to create, insert, append, erase, reverse, and print. The program should ask the user what required by the function to prepare the real function call. For instance, for the insert function, the string might be printed on the screen as a reminder first, and then the start and finish indexes might be requested from the user. You should be aware of the run-time issues that might result due to user mistakes. Try to prevent them!Design and write a C program that performs the following functionality:1. Prompt the user to enter a vector of maximum 10 digits. Note: the vector entered cancontain spaces.2. Read and store the vector that can contain spaces.3. Use a recursive function to transpose the vector from a row vector to a column vector.4. For example, if the user is prompted and enters the following in the command line(italicized and in red):Enter a vector of maximum 10 digits between 0 and 9: 1 2 3 4 55. Write a recursive function that will produce the following output (in blue):123456. Write and compile your code
