Random numbers in c++ are generated using functions such as rand() and srand() located in <cstdio> i.e. the C standard library. For those who use turbo c++, it you can find these functions in <stdio.h>.
// Program to generate random numbers
#include <iostream>
#include <cstdlib>
int main()
{
int x;
std::cout<<" Enter the max limit : ";
std::cin>>x;
srand(time(0));
for (int i=0; i<20; i++)
{
std::cout<<rand()%x<<std::endl;
}
std::cin.get();
return 0;
} // end of main
#include <iostream>
#include <cstdlib>
int main()
{
int x;
std::cout<<" Enter the max limit : ";
std::cin>>x;
srand(time(0));
for (int i=0; i<20; i++)
{
std::cout<<rand()%x<<std::endl;
}
std::cin.get();
return 0;
} // end of main
