Tests(0/0):

Code:

#include <iostream> using namespace std; int main() { double a[1005]; int n; double t; cin >> n; for (int i = 1; i <= n; i++) { cin >> a[i]; } double min = abs (a[1] - a[2]); for (int i = 1; i <= n; i++) { for (int j = i + 1; j <= n; j++) { t = abs(a[i] - a[j]); if (t < min) { min = t; } } } cout << min; return 0; }

Run Info:

Main.cc: In function 'int main()':
Main.cc:11:30: error: call of overloaded 'abs(double)' is ambiguous
 double min = abs (a[1] - a[2]);
