No, some of them are not compiled, but interpreted (languages perl, python, php, ruby etc,).
Some C programs can be compiled in C++, yes.
No it is because compiled programs are scared so they run like stink. Plus, uncompiled programs, ie. source programs, do not run at all... neither slowly nor fast.
All compilers were not written in C. Some are written in Assembly Language.
The only program that executes during compilation is the compiler. The compiler produces one object file for each translation unit compiled. When all translation units are compiled, the object files can then be linked together by executing the linker.
When programs written in most other languages are compiled, they produce a platform-dependent executable that only runs on the same type of computer (i.e. 64-bit Windows or Intel Macs) it was compiled on.When a Java program is compiled, on the other hand, it produces a Java .class file that contains Java bytecode. That bytecode runs the same on almost all computer types because the Java virtual machine takes it and compiles it to platform-dependent code just before it runs.
when you download source code, it's usually compiled using these steps: 1. ./configure configures the software for compiling, used for enabling various features 2. make does all the compiling, turns the source code into programs using instructions created by the first step 3. make install moves the compiled programs to somwhere in the system that's in the system PATH varaible
They all were written by people. Some were written by people who were told what to write by God. Some are accounts of the Lords people and whomever compiled the first bible saw fit to add them.
All software is written. Hardware is the bits of your computer which are fixed, such as the keyboard, monitor, and so on. Software refers to the programs that are written to instruct it all how to work.
Budget manual should be compiled after all budgets have been set.it is false
it set the foundation for all of todays technology in space
Not all programs are written in the same programming language. Every compiler can translates only one type of language into object code.
As far as I know, interpreted software does not run compiled software at all.
