problem with cin>> and getline

[Scorvus]

I have problem with cin>> and getline. The getline function somehow steal the input I enter earlier from the cin>> function.

int main()
#include<iostream>
#include<string>
using namespace std;
{
	string line;
	int tc,count=1;
	cin>>tc;
	while(tc--)
	{
			getline(cin,line);
			translate(line,count);
			count++;
	}
}

You are half-way to an explanation. The getline() doesn't 'steal' anything which was accepted by an earlier cin >>. What it does is use anything which was left over, in the input buffer after that cin, which will usually be a newline character '\n', but if the user typed something other than was requested by the earlier input, there could be many characters remaining.

After cin >> use cin.ignore() or something like cin.ignore(1000, '\n') to get rid of the unwanted characters in the buffer.

after the cin>>tc write cin.flush();

It works! Thanks!

sorry 2 questions, cin.flush() the same as cin.sync()?

and how does while(int--) work? I though while required a bool or comparable statements?

Edit: Just continues till it hits 0, sorry ignore the second question that was dumb.

std::istream doesn't have a member flush as described by the standard.

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

#include<iostream>
#include<string>
using namespace std;

These should be written at the very start of your program for your compiler, not inside your main function

doesnt make a difference in this case though (well if its inside the brackets; it cant be immediatly after main like that i believe but int main() { headers and std } is fine)
