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 1.5. Memory Layout Given the C struct definition below struct Simplestruct { int i; char c; double d; unsigned char a[11]; float f; }; struct Simplestruct ssp; Assume that int's are 4 bytes and have 4 byte alignment and that double has 8 byte alignment and float has 4 byte alignment. if calling printf("$x\n",ssp) yields CA028, what is the address of each field? You should express the answers in hexadecimal. &ssp->i = &ssp->c = &ssp->d = &ssp->a = &ssp->f =
- Module/Week 5 ASSIGNMENT (USER-DEFINED FUNCTIONS)Write a C++ program that reads data from an input file, takes the data and computes student grades for an assignment by converting the raw score to a percentage given each student's score and the total points. The final score must be rounded up to the nearest whole value using the ceil function in the <cmath> header file and displayed as a percentage. You must also display the floating-point result up to 5 decimal places. You must use at least 2 functions: one to print the last name of the student and another function to compute and print the percentage as well as "Excellent" if the grade is greater than 90, "Well Done" if the grade is greater than 80, "Good" if the grade is greater than 70, "Need Improvement" if the grade is greater than or equal to 60, and "Fail" if the grade is less than 50. The main function is responsible for reading the input file and passing the appropriate arguments to your functions. Here is an example of…C code blocks Implement a function which receives a character array and determines if the word is a palindrome or not. A palindrome is a string that is spelt the same way forwards and backwards (see the example below). The function should return 1 if the character array is a palindrome and 0 if it is not. Write the entire function in the space below. Your answer should not include the function prototype, the main function or any include statements. The function should not contain any printf statements. Define your function in the same way as the given function prototype. Function prototype: int palindrome(char a[]); For example: Input Result hello 0 radar 1 acca 1#include <string> // for string processing#include <iostream> // Access input output stream: cin coutusing namespace std; // Access cout, endl, cin without using std:: as prefix// 8 global variables and 7 prototypes of functionsstring pw; // global pw for the password to be checkedbool r1, r2, r3, r4, r5, r6, r7; // global 7 boolean flags for violationsvoid s1(); void s2(); void s3(); void s4(); void s5();void s6(); void s7(); // 7 prototypes of functions to be defined after main() int main() // like a driver to call those 7 functions to check a password {// begin of main // must return integer to the callercout << "Welcome to the PASSWORD game designed by Joel!" << endl;cout << "Please enter a password:" << endl;getline(cin, pw); // pw may have blanks anywhere, so must use getline( )cout << "Your password \"" << pw << "\" " ;while (pw != "quit") // the password is not “quit”{ //begin of while loops1(); s2(); s3(); s4();s5(); s6();…
