Reading a file requires printing words that meet certain conditions.

The condition is that the first two characters must be given two letters, such as he. If the words in the file start with "he", print them out.

This is a simple implementation.

# Include <iostream>
# Include <fstream>

Using namespace STD;
Char SEPs [] = ",/t/"/n .? ";
Char * token;

Int main ()
{
Ifstream ifs ("test.txt ");
If (IFS = NULL)
{
Cerr <"the file was not opened." <Endl;
Exit (1 );
}
String STR;
String SRC;

While (Getline (IFS, STR ))
{
SRC + = STR;
}
Cout <SRC <Endl;
Int Si = SRC. Size ();
Char * pstr = new char [Si + 1];
Strcpy (pstr, SRC. c_str ());

Cout <Endl;

Cout <"Haha. The result is the below words." <Endl;

Token = strtok (pstr, SEPs );
While (Token! = NULL)
{
/* While there are tokens in "string "*/
STR = token;
If (Str. substr (0, 2) = "he ")
{
Cout <STR <Endl;
}
/* Get next token :*/
Token = strtok (null, SEPs );
}
Cout <Endl;
Delete [] pstr;
System ("pause ");
Return 0;
}
