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)
- generate a random number between 1 - 100
- display the number back to the user
- determine which quartile the number falls in (using any combination of if, else, and else if)
- display the quartile back to the user
- display a "goodbye" message (more descriptive than shown in sample)
SAMPLE OUTPUT: (changes every time program is run...)
Hello.
Random number generated: 3737 falls in the second quartile (26 - 50)
Goodbye.
