Posted on 16th Feb 2014 07:03 pm by admin

Hi Everyone ,

I am having issue with istream declaration. I am new to C programming.
can any one please help me ?

I am getting error in getNameValuePair.h and getNameValuePair.C code.

Here below the compilation result .

Stop.


Here below getNameValuePair.C header files declaration part

//#pragma VERSIONID "@(#)getNameValuePair.C 1.2"

// System Header Files
#include
#include
// #include
// Unit Header Files
#include "getNameValuePair.h"

//istream &
istream &getNameValuePair(string &name, // first token found on input line
string &value, // second token found on input line
istream (&input)) // stream from which to extract line

Here below content of getNameValuePair.h

// Interface to utility function to help parse a file of name-value pairs.
// Lines are broken into tokens separated by white space.
// Lines without tokens are ignored.
// Lines whose initial token begins with "#" are ignored.
// The first token on a line is assigned to name.
// If there is a second token, it is assigned to value.
// Any remaining tokens on the line are discarded.
#include
//#include
istream &getNameValuePair(string &name, string &value, istream &input = cin);

Can you please anyone help me out for this issue ?

we create service request to RW vendor about this compiler problem. they told us to change header file declaration part like to . ( the above code is not updated - original source code)
after we have done the changes also, it gives same error .

can any one tell me what should need to change in above code ?
Thanks is advance
