float genRandFloat( float a, float b );
int main(void)
{
int i;
float low = 0.3, high = 0.6;
//Seed with the time.
srand ( (unsigned)time ( NULL ) );
//Seed 20 random numbers between low and high
for(i = 0; i < 20; i ++)
printf( "%f\n", genRandFloat(low, high) );
return 0;
}
float genRandFloat( float a, float b )
