See there are two different part in this picture let's understand this,

//source program, pseudo code

print "Hello World"

so above program is a source code of print hello world now there are one type of languages like C, C++, Java, what happens when you write your code in a code editor or IDE, the time you triggered the compile & run button from that particular time your given code passes through some steps like, firstly it going to preprocessor then going to get compiled after compilation it converted to .obj file and that obj file getting converted to .exe file and then it executed and showing output,
