练习求数组的最大值或最小值

using namespace std;
namespace Com {
int maxOrmin(int *arr, int length, bool isMax) {
int temp = arr[0];
for (int i = 1; i < length; i++) {

}
}
else {
if (temp > arr[i]) {
temp = arr[i];
}
}
}
return temp;
}
}

int main()
{
int arr[4] = { 7,5,6,9 };
bool isMax;
cin >> isMax;
cout << Com::maxOrmin(arr, 4, isMax) << endl;
system("pause");
return 0;
}
