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.

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
