Hi! Here i wrot a little program to split a cpp string into tokens without getline. The several tokens will save in a vector of cpp strings. After this done the several vectors are converted into integer values first header strwork.h: Code: #ifndef STRWORK_INC_ #define STRWORK_INC_ 1 #include <iostream> #include <stdlib.h> //atoi EXIT_SUCCESS #include <string.h> // strcpy, strtok #include <vector> #include <sstream> // stringstream #include <complex.h> std::string showchar(int nummer); int StrToInt(std::string zawo); int is_allowed(std::string mot, std::string erlaubt); int showvector(std::vector<std::string> tokens); #endif now strwork.cpp: Code: #include "strwork.h" std::string showchar(int nummer) // old DOS 437-font charctes 166 and 167 are of font 851, beceause characters of font 437 not showable { //128 142 145 146 147 //148 149 150 155 160 165 int i = 0;

return EXIT_SUCCESS; } I wrote std::string showchar(int nummer) to convert old files where written with MSDOS to files for Linux. But i hope, it can be used by people with Windows Have much fun rustyoldguy
