How a language handles its source code differs, but generally the code is compiled into a simpler form (bytecode, machinecode, etc) for most applications software.
If you don't compile and execute your program, then it's not a program, just a bunch of source code which is worthless to the computer. The whole point of a compiler is to turn the human-readable code into machine-readable code.
There is no such thing: compiler translates but doesn't execute; interpreter executes, but doesn't translate.
Yes. One program can execute another program very easily -- you can even do it via scripting languages and batch programming. Morevoer, programs that provide shared code via one or more libraries make it possible for another program to execute code within those libraries, just as if that code were part of the program itself (no need to execute another program). Such programs often provide application programming interfaces (APIs) to simplify the process of integration.

It depends on which specific program you have in mind. Native machine code programs do not require any software to run; the program was converted into the machine's native language during compilation and does not require further translation. However, machine code is non-portable. To execute the same program on another platform the source code must be recompiled for that platform. Conditional compilation directives ensure that the correct machine-specific source code is compiled. Byte code programs, however, do require software to execute. Byte code is not native machine code so must be converted to native machine code while it is executing. This is achieved using a runtime program known as an interpreter. Java is a typical example. Java source code is compiled to Java byte code suitable for interpretation by the Java virtual machine (JVM). Thus a JVM is required to execute Java programs. Unlike native machine code, byte code is portable; the same byte code will execute upon any machine that has a suitable interpreter available.

The Concurrent Versions System (CVS for short) is an application that tracks changes to the source code of a program.
Source program or source code in any language is the code you write to make the program do what you want. Things like: #include <stdio.h> void main (); and so on are all pieces of source-code or source program
It coverts your source code into machine code so the computer can execute it.
A Computer Program (also software, or just a program) is a sequence of instructions written to perform a specified task with a computer. A computer requires programs to function, typically executing the program's instructions in a Central Processor. The program has an executable form that the computer can use directly to execute the instructions. The same program in its human-readable source code form, from which executable programs are derived enables a programmer to study and develop its algorithms.
a compiler translates an entire program and then executes it while an interpreter translates and executes one line of a program at time
