hi guys,
i have been trying to make this thing work .heres the code for calculator by the way. Everything compiles fine except for push_back(). heres the code snippet.
Code:
Token_value get_token()
{
char ch ;
do{
if(!cin.get(ch)) return curr_tok = END;
}while(ch !=( '/n' && isspace(ch)) ) ;
switch(ch){
case ';' :
case '\n' :
return curr_tok = PRINT ;
default : // NAME, NAME = , or error
if( isalpha(ch)){
string_value = ch ;
while( cin.get(ch) && isalnum (ch)) string_value.push_back(ch) ;//HERES THE ERROR.
cin.putback(ch);
return curr_tok = NAME ;
}
error("bad token");
return curr_tok = PRINT ;
}
}
THE COMPILER ERROR:->
53 deskcalc.cpp no matching function for call to `basic_string<char,string_char_traits<char>,__default_alloc_template<false,0> >::push_back (char &)'
push_back does take char . doesnt it?? if theres any mistake then please let me know. Atleast i will be able to learn from my mistake.
iostream , cctype, string, map has already been included.Map is needed to create a table of strings.
