How do you generate two random numbers in C plus plus?

Answer 1

#include <stdio.h>

#include <stdlib.h>

#include <time.h>

int GetRand( int min, int max)

{

// Swap min and max if wrong way around.

if(max<min)min^=max^=min^=max;

return(rand()%(max-min+1)+min);

}

int main()

{

// Seed the random number generator with current time to ensure

// random numbers are different on each run.

// Note: use srand(1) to generate the same sequence on every run.

srand((unsigned)time(NULL));

printf("Number from 0 to 10 : %d\n", GetRand(0,10));

printf("Number from 1 to 100: %d\n", GetRand(1,100));

return(0);

}
