Answer:

#include <iostream>

using namespace std;

int main() {

   srand(time(0));

   for(int i=0;i<5;i++)

   {

      double f = (double)rand() / RAND_MAX;//generating random numbers.

       double a= 5.0 + f * (15.0 - 5.0);//random numbers in range provided.

       cout<<a<<" ";

   }

return 0;

}

Explanation:

The above program generate five random numbers in the range 5.0 to 15.0.The function rand() is used to generate random numbers.First we have to call srand(time(0)) otherwise the rand() function will generate same random numbers over and over every time.

B-because much intellectual theft is committed in other countries

However, as this work is complete, the B option will not be an issue related to intellectual theft analysis and control.

And  C and D are definitely not the part of the answer, as associations like FCC USA, Internet association etc  are technically sound enough, and quite good to fight a case under any law as well.
