Instructions:
You are provided with the isLeapYear() function which is already declared and defined for you.
Your task is to ask the user for a year and then call the isLeapYear function to check whether the year is a leap year or not.
Input
1. Year to be checked
Output should be like this:
Enter year: 2020
2020 is a leap year
note: If a certain year is a leap year, print "<INSERT_YEAR_HERE> is a leap year" Otherwise, print "<INSERT_YEAR_HERE> is not a leap year"
MY CODE: (IN C LANGUAGE PLEASE)
#include<stdio.h>
int isLeapYear(int);
int main(void) { // TODO: Write your code here
return 0;}
int isLeapYear(int n) { if( (n % 4 == 0 && n % 100 != 0) || (n % 100 == 0 && n % 400 == 0) ) { return 1; }
return 0;}
Usernames
An online company needs your help to implement a program that verifies the username chosen by a new user. Their rules is described below:
Username MUST contain at least 6 characters;
Username cannot start with a number;
Username can only contain letters or numbers.
If valid, the username may be resgistered if it doesn't already exist in the system.
You should not use built-in functions to determine the character type such as isnumeric() or islower().
Use the strings given alphabet and numeric to determine if each character is valid.
Use the list registered to help you determine if the username is already registered.
Don't forget to execute the cell below to use these strings
# run this cell to create these variablesalphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz'numeric = "0123456789"registered = ["john87", "topmage", "light4ever", "username2"]
Write a function nameValidation which receives a String argument name. This function:

- C programming Design a program that will record and display the distance between the rocket and the asteroids. Problem description The rocket is traveling through space. Each asteroid has (x, y, z) position in space, where x, y, and z are the distances in kilometers from the rocket which is at 0,0,0. It will read a file asteroids.txt that represents the ID and location of each asteroid. The distance between the rocket and each asteroid is calculated based on the asteroid’s X, Y, Z position using the following formula. √(x2+y2+z2) This program must be secure. The user puts their name and password, if both match the list you have in a text file on the disk (ID.txt), then the user gets access to the program. The program should allow 3 tries for name and password entry, if unsuccessful after 3 tries the program should print a message and terminate.
