Stop new line for C++ cin -
in c++, iostream automatically puts in new line after cin. there way rid of this?
i want use iomanip format information table, so:
cin cout 0.078125 3da00000 -8.75 c10c0000 23.5 41bc0000
(random numbers)
example code:
#include <iostream> using namespace std; int main() { int num; cin >> num; //now new line. cout << num << endl; return 0; }
you presumably pressed return key send input command line program's standard input. that's newline coming from. can't read number cin
before newline appears in console, because newline causes console hand input on program in first place. could, user, configure console (or whatever running program) act differently, there's no way program force such behavior.
if want have input , output on same line, need find way "write previous line". how works depends on console (see how rollback lines cout?). there no standard way because cin
, cout
in no way obligated attached console or resembling one, not clear "writing previous line" means anything.
