我在试着恢复。txt文件的文本，把它变成一个记录，以创建一个基本的“全球定位系统”。我确实设法把文本变成了一个记录，然而，代码运行的时间越长，出现的错误就越频繁（比如它写的是“hungry”而不是“hungry”）。

#define TRUE 1

  string action[49],preconds[24],add[24],delete[24];
  int NbPreconds,NbAdd,NbDelete;
}Event;

  int i=0, n=0; // i: source[], n: cible[]
  while(source[i]!=':') i++; // go until ':'
