#include<stdlib.h>The ANSI C standard library provides functions for generating random integers. Before generating random numbers, you must make sure that

__you initialize the random number generator with a random seed__. This random seed can be provided by using the current time. This means you will also need to use the ANSI C time operations library:

#include<time.h>

__Example:__time_t seconds; int randomNumber = 0; double realRandomNumber = 0.0; /*Returns the number of seconds since 1 January 1970*/ time(&seconds); /*Initializes the random number generator*/ srand(seconds); /*Generates a random integer between 0 and RAND_MAX*/ randomNumber = rand(); /*Generates a random integer between 0 and 255*/ randomNumber = rand()%255; /*Generates a random integer between 127 and 255*/ randomNumber = rand()%(255-127) + 127; /*Generates a random integer between -127 and -255*/ randomNumber = - (rand()%(255-127) + 127); /*Generates a random integer between -127 and 255*/ randomNumber = rand()%(255+127) - 127; /*Generates a random floating point number between 0.0 and 255.0*/ realRandomNumber = (double)(rand()%2550)/10.0; /*Generates a random floating point number between 127.3 and 255.4*/ realRandomNumber = (double)(rand()%(2554-1273) + 1273)/10.0; /*Generates a random floating point number between -127.3 and -255.4*/ realRandomNumber = - ((double)(rand()%(2554-1273) + 1273)/10.0); /*Generates a random floating point number between -127.3 and 255.4*/ realRandomNumber = (double)(rand()%(2554+1273) - 1273)/10.0;

__Notes:__- You can obtain real random numbers by transforming the floating point number into a integer (ex: 253.23 -> 25323) and after using
*int rand()*, dividing the result with 10^n (where n represents the number of digits after the decimal point). - You can obtain negative numbers (either integer or real) by applying the same rules as for positive and multiplying the result with -1.
