Explanation / Answer
#include <stdio>
#include <iostream>
#include <cstdlib>
#include <ctime>
unsigned int generateRandomNumberInRange(unsigned int lowEnd, unsigned int highEnd)
{
if(highEnd < lowEnd)
{
unsigned int tempForSwap = highEnd;
highEnd = lowEnd;
lowEnd = tempForSwap;
}
int rangeVal = (highEnd - lowEnd) + 1;
return (std::rand() % rangeVal) + lowEnd;
}
int main()
{
std::srand(std::time(nullptr));
unsigned int randBetweenOneAndFifty = generateRandomNumberInRange(1, 47);
std::cout << randBetweenOneAndFifty << std::endl;
unsigned int randBetweenOneAndFifteen = generateRandomNumberInRange(1, 47);
std::cout << randBetweenOneAndFifteen << std::endl;
return 0;
}
}
