tested only with Turbo C/C++
Code://libraries #include <stdio.h> //defines scanf() and printf() #include <stdlib.h> //defines rand() #include <time.h> //defines time() and is needed for randomize() #include <conio.h> //defines clrscr() and getch() //main int main() { //declaring a variable int random; //clearscreen clrscr(); randomize(); random = random(100); //display result printf("\nRandom numbers in the range 0-99: %d",random); //wait for a key to be pressed by user before program exits getch(); }//end main
Note:
1) The randomize() initialises the random number generator, rand(), with a value.
2) The code can work without the randomize() function, BUT without it your computer will only generate same number each time.
So, the randomize() is there to generate different random numbers with "time" and hence u need to include the library file <time.h>
3) The function rand(100) generates random numbers between 0 and (100-1). That is numbers between 0-99.
4) If you want to display 20random numbers, just call the generator in a for loop with "counter <= 20", like for(int counter=0;counter <= 20; counter++)
well, that's what i know...any suggestions are welcomed!
