- 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: 3Homework ● Write a function C++ void switchEnds(int *array, int size); that is passed the address of the beginning of an array and the size of the array. The function swaps the values in the first and last entries of the array.C code blocks Write the complete function that receives a pointer to a single floating point number as an argument and returns that number after subtracting 100 from it. Define your function in the same way as the given function prototype. Take a look at the "For example" below to see how the function is used in the main function and the expected result. (For interest sake, note that this is a pass-by-reference function call.) #include <stdio.h>#include <stdlib.h>void subtractFunc(float *a);int main(){ float num = 357.900; subtractFunc(&num); printf("%.3f", num); return 0;} //Your answer starts here For example: Test Result float num = 357.900; subtractFunc(&num); printf("%.3f", num); 257.900
- C++ Pointers must be used to solve the following problem. Write a function createPassword() with no return value to randomly select 8 capital letters from the alphabet. The function receives the address of the first characters of the password string as parameter. Hint: Declare a characters string that contains all the capital letters of the alphabet and use the index values of the characters in the string for random selection of characters, e.g.char alpha [27] = “ABCDEFGHIJKLMNOPQRSTUVWXYZ”;char *pAlpha = alpha; Display the password from the main() function. Write a function replaceVowels() with no return value to replace all the vowels (A, E, I, O, U) that have been selected with a symbol from the list ($ % @ # &). That is, A must be replaced by $, E replaced by %, I mustbe replaced by @, O replaced by #, and U must be replaced by &. The function receives the address of the first characters of the password string as parameter. Display the password agin from the main()…Write a c++ program: NOTE: Pointers must be used to solve the following problem.

Both function calls are for the same function but with different parameters.
- 1. Write a C++ function named "extractDebugOption" that accepts arguments similar to argc (an integer for the array size) and argv (an array of pointers to C-string). It will determine whether it has the argument of "/debug yes" or "/debug no". It will return true if the debug option is yes. If "/debug no" or there is no debug option or "/debug" without "yes" or "no" followed, it will return false. Note: command line arguments are simply an array of pointers to C-string. Please test it with the following command line arguments These will return true"/debug yes""/compile /debug yes" These will return false"/debug no""/debug""debug""yes /debug""no /debug"In a function aFunction, we have 2 values: num1 (float type), num2 (int type) declared locally and assigned to 2.1 and 6. Write code segment to return the two values from function aFunction.s buipeay E Write a well-documented C++ program consisting of the following two functions. • Write a function that accepts an array of integer elements and its size as parameters, swaps the two halves of the array as shown below. If the array contains the following: 5 9 2 12 8 4 Then your function should swap the two halves of the given array so as it becomes as follows: 12 8 4 5 9 • Write a function main () that defines an array consisting of 13 integer elements and performs the following tasks in order: • fills the array by prompting the user to enter 13 integer values from the keyboard; • displays all array elements separated by two spaces. • swaps the two halves of the array by calling the above-defined function. • displays all array elements (after swapping) separated by tabs. Hints 1. Develop and check the correctness of the tasks in a and b parts before starting parts c and d. 2. Try and practice the following program structures: o your program, write the main () function after…
- 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.Write a statement that declares a prototype for a function divide that takes four arguments and returns no value. The first two arguments are of type int. The last two arguments arguments are pointers to int that are set by the function to the quotient and remainder of dividing the first argument by the second argument. The function does not return a value.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;}
