Faster input and output

Question

#include
using namespace std;
int main(){
    int i,x,max=0;
    cin>>x;
    int a[x];
    for(i=0;i>a[i];
        if         


        

Answer 1

Avoid cin and cout, and use the C IO functions scanf and printf instead. You'll find they can be up to 5x faster than the slow c++ functions.
