When we are writing any program we have three choices
1.Programming Language
2.Scripting
3.Markup Language
Programming Language :
We consider that the example below is for C/C++
We have some basic steps :
1.Write a program
2.Compile it via compiler.
3.Link the program
4.run it
We can write the program in any editor even in Notepad++.
Visual Studio is a IDE (Integrated Development Environment) from Microsoft which is able to combined all the above steps.
when we write a program like this
| //file: test.cpp #include <iostream> using namespace std: int main(){ cout<<”Hello this is first output”<<endl;
|
Visual Studio is used to write the above C++ program .
After writing the program , it is being compiled.
Once the program is compiled(compiler) , its create object file similar to test.obj
after that compilation , test.obj is linked with C++ library(Linker perform this ) and executable file is produced.
it will be named like test.exe (In Linux environment it will be test.o)
.exe is a special file type in windows , which denote to a program executable.
Once the file is clicked , Operating system gives control to this program .
First line from where the program start is main() ….
all the subsequent line is executed one by one , once it reach to return 0;
or any return int ; on the last statement of program ,
program return the control to Operating system .
Visual studio or any other compiler (like GCC ,DevC++)can be used to compile and run the program .
