Can anyone please tell me the syntax of accepting line ( string ) as an input in c++ along with header file required for it ?

Answer 1

int count = 0;
for(int i = 0; i < line.size(); i++) {
if(line[i] == 'k') {
count++;
}
}
cout << count << endl;

Answer 2

cout << line << endl;
//For outputting the line

Answer 3

It's not necessary, but go ahead and #include <string>, then:

string line;
getline(cin, line);

This will accept white space as well, so you can enter multiple words.
