reading strings from a file

[tyky9808]

HELP! This program is due on Monday. I've been at it for a week now. Can seem to get it running correctly. Tne program reads text from a file and uses functions to make a substring, check which string is larger, if they are the same, what character types are in each string and if the word in the first string is in the seond string. Please help me I'm lost.Sorry for this long code.
This is the data in my file:
Feliz Navidad!!
Happy BIRTHDAy
!my sunshine%
love love
won $500
33 today
sage message
No refun%*
chest orchestra

This is my code so far:
[code][///This program will read strings from a file.
//It will use a function to split each sctring.
//It will use a function to evaluate if the strings are the same
//It will use a function test each character in each string and check what kind
//of character it is.
//It will use a function to get the larger of two strings
//Finally it will use a function to determine if one string is a substring of another

bool snipsame(string, string &);
int main()
{
string first;
string second;

ifstream textin("program7.txt");
ofstream textout ("program7.out");

if(!textin.is_open()){
cout<<"unable to open the file stream textin" <<endl;
exit(1);
}

split(first, second);
textout<<first<<endl;
textout<<second<<endl;

if(same(first, second)){
textout<<first<<" "<<second<<"match"<<endl;
chartype(first);}

else
chartype(first);
textout<<"The larger string is "<<is_larger(first, second)<<endl;

snipsame(first, second);
getline(textin, first);
}

textin.close();
textout.close();
return 0;
}

//Function to split the original string at the first whitespace

return;
}

return;

Where is it going wrong?

It's supposed to print the original string on one line with the length of the string. Then after calling function split(). Main will print the two strings. After calling function same() main will print if they match . If they don't then main calls function chartype() to check the character type for each character in the string, it will also call is_larger to see which string is larger i.e closer to the end of the alphabet. Function snipsame () will check if the word in the first string is part of the second string. If the function returns true, it will remove the substring from the second. IF the function returns true main should print the second string otherwise main will print ;no changes made. Finally main should concatenate the strings in reverse of the original order and print the result. My output is nowhere near this. I don't even know where to start. Please help
