Compiled and made into executable using Dev C++

I am using windows 7 64-bit operating system .

Which software should i use to see its source code in assembly language .

IDA Pro is what you should use

If you can't afford the 700 bucks for IDA, use Olly or, in 64-bit land, its 64-bit clone.

Thanks for the reply .
I was able to find a version of IDA Pro 6.8 from a site , and it works :-)

The problem is i cant find enough source code to compile and study
