You can't get back the original C source code from the compiled binary - there are many ways in C of producing the same end result so there isn't a unique source.

The process is called <a href="http://en.wikipedia.org/wiki/Decompiler" rel="nofollow noreferrer">decompiling</a>

If I have misunderstood your question and you want to know how to view the assembler that the compiler generates from your C code then that depends on the particular compiler but they can all do it. See <a href="https://stackoverflow.com/questions/1354899/how-can-i-see-the-assembly-code-that-is-generated-by-a-gcc-any-flavor-compiler">How can I see the assembly code that is generated by a gcc (any flavor) compiler for a C/C++ program?</a>

blocks|key|2045803|text|你是在问如何逆转吗？你应该搜索逆向工程，然后从那里出发。您将需要使用一个反编译器，知道一点组装，仍然没有成功的保证，你将能够得到所有的原始代码。如果程序最初有多个文件或某种隐藏技术来随机化代码(混淆)，那么它也会变得更加困难。你需要做大量的工作才能与原始代码有很大的相似之处。以下是主题：工程学的维基百科链接|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|2045804|，但是，在您的地区，它可能是非法的，取决于您如何处理它，请不要陷入麻烦！|style|BOLD|2045805|注意：，如果这个帖子是不允许的，请告诉我，我马上把它取下来。|2045806|编辑:我相信它也可以被称为反编译。|2045807|entityMap|0|LINK|mutability|MUTABLE|url|http://en.wikipedia.org/wiki/Reverse_engineering^0|40|3|0|0|0|10|0|0|3|0|0^^$0|@$1|2|3|4|5|6|7|T|8|@]|9|@$A|U|B|V|1|W]]|C|$]]|$1|D|3|E|5|6|7|X|8|@$A|Y|B|Z|F|G]]|9|@]|C|$]]|$1|H|3|I|5|6|7|10|8|@$A|11|B|12|F|G]]|9|@]|C|$]]|$1|J|3|K|5|6|7|13|8|@]|9|@]|C|$]]|$1|L|3|-4|5|6|7|14|8|@]|9|@]|C|$]]]|M|$N|$5|O|P|Q|C|$R|S]]]]

so are you asking how to reverse it?
you should search up reverse engineering and go from there.
you will need to use a decompiler, know a bit of assembly and there
is still no guarantee of success, that you will be able to get all the original code. 
it will also get harder if the program originally had more than one file or some sort of hiding technique to randomize the code (obfuscation). You will need to do alot of work to get even a bare-bones resemblance of the original code.
here is the Wikipedia link for the topic: <a href="http://en.wikipedia.org/wiki/Reverse_engineering" rel="nofollow">http://en.wikipedia.org/wiki/Reverse_engineering</a>

HOWEVER, IT MAY BE ILLEGAL IN YOUR AREA, Depending on what you do with it, please don't get in trouble! 

NOTE: if this post isn't allowed, someone please let me know and i'll take it down immediately.

EDIT: It can also be called decompiling as well i believe.

use ollydbg and find your code within the disassebly :)

for example compiled code

<pre><code>int main()
{
 system("PAUSE");
 return 0;
}
</code></pre>

would be hard to find in all the lines of the disassebly but if you pad it you can find it easier for example... compile this code

<pre><code>int main()
{
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");

 //mycode
 system("PAUSE");

 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 asm("nop");
 return 0;
}
</code></pre>

and now in the disassembly i will be able to see the rows of "nops" and in between them is my code in binary form

so you can see that my system call is compiled into

i hope this is what you meant :)

This can be done with ollydbg or x32dbg or objdump -M intel -d ;)

If you compile with debug information embedded in the object files ( binary output files generated by compiling the source files ), links to the original locations of the source files will be embedded in the object files. This allows a debugger ( e.g. gdb ) to jump to the line in the source file corresponding to a breakpoint when that breakpoint is encountered whilst debugging the program. You can compile with debug info added by specifying the -g switch if you're using gcc. For example:

<pre><code>gcc -g -o myProgram myProgram.c
</code></pre>

compiles myProgram.c into a executable myProgram which you can run or debug. To debug myProgram you can use gdb:

<pre><code>gdb myProgram
</code></pre>

This is commonly described as "turning hamburger back into cows." 

A decompiler will generate C source code that's functionally equivalent to the original code, but it won't have any of the original symbol names, and may not be structured the same. It may not even be very "readable".

You cannot recover the original source from a compiled program.

 The compiler is what takes this code, and translates it into the machine code
