Write a program to generate a random number between 1 - 100, and then display which quartile the number falls in.
First quartile is 1 - 25
Second quartile is 26 - 50
Third quartile is 51 - 75
Fourth quartile is 76 - 100
To generate a random number, follow these steps:
include necessary header files
#include <cstdlib> //for random functions
#include <ctime> //for time functions
set constants for the minimum and maximum values of the desired range
const int MIN_VALUE = 1; //minimum range value
const int MAX_VALUE = 100; //maximum range value
seed the random number generator (RNG) with a unique unsigned int value - system time!
unsigned seed = time(0); //system time in seconds since 1/1/1970
srand(seed); //seed the RNG
get a random number in the desired range
int num = (rand() % (MAX_VALUE - MIN_VALUE + 1)) + MIN_VALUE;
The program should:
contain header comments as shown in class
display a "hello" message (more descriptive than shown in sample)…
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.
Program Input
-The name and password of the user.
- A file called ID.txt which contains names and passwords. Example below:
John 11234…

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;}
