Now answer…
remove getchar()

i need getchar() to enter a character first.
it’s mandatory.
Then simply do
char ch;
string s;
cin>>ch>>s;
cout<<ch<<" "<<s;
You can use string for both of them.A single character is also a string.
string s1,s2;
cin>>s1>>s2;
cout<<s1<<" "<<s2;
Actually getchar() is essential before cin in my code.
So suggest a way to implement the original code.
And if i remove ios_base::sync_with_stdio(false), my code works perfectly. Can i know why so ?
