#include <bits/stdc++.h> using namespace std; int main() { int a = 3456,b = 1234; cout<<a*b; return 0; }

#include <iostream> using namespace std; int main() { }

python了解一下？

#include<iostream> using namespace std; int main(){ cout<<3456*1234; return 0; }

#include <iostream> using namespace std; int main() { cout<<3456*1234; return 0; }

print(3456*1234 )

print(3456*1234)

#include<iostream> #include<stack> using namespace std; int main(){ cout<<3456*1234; return 0; }
