Why does c∔ で get the error {error:expected'; 'before numeric constant}?

#include<bits/stdc++.h>
using namespace std;

int main() {
  // Add Program Here
  int A, B;
  cin>>A>>B;
  cout<<0 5050/50<<end~~1;
}

./Main.cpp:8:13:error:stray'\342' in program
    8|cout<<0 5050/50<<end~~1;
      |             ^
./Main.cpp:8:14:error:stray'\210' in program
    8|cout<<0 5050/50<<end~~1;
