Yes. The easiest way would be to simply execute the compiler with the source file as input:

sprintf(cmd, "gcc %s", filepath);

system(cmd);       /* Compile */
system("./a.out"); /* Execute */

Otherwise you're looking at running the code through an interpreter of some sort, which could be as simple as using an existing interpreter similar to above, or writing a form of eval() that handles C code (not a task taken lightly).

Ultimately, I'd say that C probably isn't the correct choice of language if dynamic evaluation of code is a necessary feature.

does this works in turbo c?
am not sure that "gss" is used in turbo c
My sir said once about this as it will be in visual c++
well Narue what is 'cmd' in this code?

I tried it but its saying "undefined symbol".
can i know what the variable cmd' is for?

Change the name of the compiler to whatever you want.

"gcc" refers to the GCC compiler.

Visual C++'s compiler is called cl.exe.

well Narue what is 'cmd' in this code?

A string! Read up on sprintf(). The idea is that we need to build a command line statement that invokes a compiler with the specified file name.

Duh. I posted a snippet, it's your job to fill in the blanks and make it compilable.
