- (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.(Statistical) In many statistical analysis programs, data values considerably outside the range of the majority of values are simply dropped from consideration. Using this information, write a C++ program that accepts up to 10 floating-point values from a user and determines and displays the average and standard deviation of the input values. All values more than four standard deviations away from the computed average are to be displayed and dropped from any further calculation, and a new average and standard deviation should be computed and displayed.C Program Functions using Pointers Create a function modify that accepts an integer and divides the integer by 2 if it is even. If the integer is odd, add one and divide it by 2. The function does not return anything. In the main function, write a program that asks for an integer input and call the modify function by passing in the reference of that variable as a parameter. An initial code is provided for you. Just fill in the blanks. Input 1. One line containing an integer input Output Enter a number: 5 Before: 5 After: 3
- Create a program in C language that calculates the month's day from a given year and year's day. Use pointers for the month and month's day variables. Don't forget to add proper errors handling in your program. Example or errors - Invalid Input- Invalid year- Invalid year day Example of input # ./month_day <year> <yearday> # Example for Feb 2nd, 2019:\$ ./month-day 2019 33Feb 02, 2019 I have this class - month-day.c - #include <stdio.h> /* month_day function's prototype*/void month_day(int year, int yearday, int *pmonth, int *pday); int main() {return 0;} Note: I don't need the calendar, please read the instructions well!!Write a program to swap two integers you should write a function named as swap_int and it should accept arguments as pointers then it should swap integers by dereferencing those pointers.Numbers that are the same as the direction of reading when they are read backwards and straight are called Palindromic numbers. Write a C program that writes to the screen whether a number entered by the user is a palindromic number. The part that finds the palindromic number will be written as a function and the Pointer will be used. Example: 101,232,3663,8008, etc.
- Using C++ Language Write a function call with arguments tensPlace, onesPlace, and userInt. Be sure to pass the first two arguments as pointers. Sample output for the given program: tensPlace = 4, onesPlace = 1 Code: #include <stdio.h> void SplitIntoTensOnes(int* tensDigit, int* onesDigit, int DecVal){ *tensDigit = (DecVal / 10) % 10; *onesDigit = DecVal % 10;} int main(void) { int tensPlace; int onesPlace; int userInt; scanf("%d", &userInt); /* Your solution goes here */ printf("tensPlace = %d, onesPlace = %d\n", tensPlace, onesPlace); return 0;}Using C++ Programming language: Assume you want a function which expects as parameters an array of doubles and the size of the array. Write the function header that accepts these parameters but is defined in such a way that the array cannot be modified in the function. You can use your own variable names for the parameters.Suppose three numbers x, y, z are passed to a function. Implement this function to assign the values of y to x, z to y and x to z and return these three changed values to main. Use pointer. Note: Use C language
- using C++ In this exercise you would be using a text input file to store a number of students first and last names, and each students scores in test1, test2, midterm, final and homeworks. Now, you get all the stored in relevant arrays. Write a function that will accept all the scores and compute the average score for each student. You can pass only one student’s information at a time while calling the function. Write another function for the grade computation. Display your results with last name, first name, average score and grade for each student. Display should be on screen as well as in an output file.pointers as Arguments:In the C programming language there is no pass-by-reference syntax to passa variable by reference to a function. Instead a variable is passed by pointer(just to be confusing, sometimes passing by pointer is referred to as pass byreference). This Practice Program asks you to do the same thing as C.Here is the header for a function that takes as input a pointer to an integer:1. void addOne (int ∗ptrNum )Complete the function so it adds one to the integer referenced by ptrNum.Write a main function where an integer variable is defined, give it an initialvalue, call addOne, and output the variable. It should be incremented by 1.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.
