C++ 40.2 Practice Help

Question

Can any one help me understand why I get a different output from the required test output?

This is my code:

#include <iostream>
#include <cstdlib>
using namespace std;

int main() {
srand(0);
int range;
cin >> range;
//your code goes here
for (int i = 0; i < 4; i++)
{
cout << 0 + (rand() % range);
}

return 0;
}

My code outputs a 4 digit number in the range from 0 to N as required, but because it does't match the expected output it fails the practice problem. Any ideas where I am going wrong?
Thanks, Mike.

Answer 1

You are using rand() which generate random numbers...
Can you add problem description for you are trying this..?

edit: Mike
there rand() produce 0 to n-1 numbers so you need add 1 to get within asking range.

#include <iostream>
#include <cstdlib>
using namespace std;

int main() {
srand(0);
int range;
cin >> range;
//your code goes here

for(int i=0;i<4;i++)
cout<<(rand()%range)+1;

return 0;
}
