C + + Instance input multiline number to array _c language

C + + input multiple lines of numbers to an array

The day before yesterday to do a company pen test, its input format is a number of lines, each with a space separator, in line with the end of the symbol input to more than one array. In Java, there are corresponding functions to split a row of groups directly, feeling in C + + This input method is still quite strange, today come up with a solution.

Ideas:

Each time a character is read, the judge is not EOF, and if it is, jump out of the loop;

Not EOF to put the character back into the buffer;

Read the line break, the end of line, processing array;

Read the character, if not a space, into a temporary string;

If it is a space, the string is converted into an integer and pressed into the array;

Attention:

For continuous space input to be judged, or you will enter a heap of 0;

The last temporary string is stored in the array when the line break is read;

Code:

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

int main () {
  char flag;
  while ((Flag=getchar ())!=eof) {
    putchar (flag);
    string tmpstr;
    vector<int> Buff;
    char c;
    while ((c = GetChar ())!= ' \ n ') {
      if (c!= ')
        Tmpstr.push_back (c);
      else {
        if (tmpstr!= "") {
          buff.push_back (atoi (Tmpstr.c_str ()));
          Tmpstr = "";
    }}} if (tmpstr!= "")
      Buff.push_back (Atoi (Tmpstr.c_str ()));
    for (auto A:buff)
      cout << a << ";
    cout << ' \ n ';
  }
}
