I am starting to learn how to use the gcc on Red Hat Linux. I'm using the Emacs text editor for making C++ Programs. This is a sample of one of the simple programs I have:

#include <iostream.h>
int main()
{
int Val, Amt, Tot, Cnt;
Amt=30;
Tot=12;
Cnt=46;

//Compute Val = rightmost expression
Val=(Amt++, --Tot, Cnt+3);

//Display the result
std::cout<<Val;

return 0;
}

After I compile it it gives me this error:

./values.cpp: Line 2: syntax error near unexpected token `('
./values.cpp: Line 2: `int main()'

I don't understand why I get this error. I would greatly appreciate your help. Thanks in advance.

try putting this line after the include statement

using namespace std;

and then try compiling the code

I put in what you told me to put in but i get this error:

./values.cpp: Line 2: using: command not found
./values.cpp: Line 3: syntax error near unexpected token `('
./values.cpp: Line 3: `int main()'

Hi there

u seem to be trying to execute the cpp file .
You can only run an executable.
The compiler compiles the code and puts the output in a.out file.

for ex.
do
g++ values.cpp
it will make a file named a.out
execute it using
./a.out

This will work and try google for some elementry tutorials on how to
compile and execute a c/c++ program in linux.
Majjj

Thanks for your help guys. It worked. The program had a few errors that I had to work out but finally it worked. I will look up in google for those tutorials. Thanks again.
