Compiling Stages in C programming | How "Compilation" work

There are four process for compiling 

1- Preprocessing

2- Compilation

3- Assambly

4- Linking

(5- Loading)

1) Preprocessing :-  

• esme hamare comments ko remove kiya jata hai. 
• Micros ko expand kiya jata hai.
• jitne bhi #include vale unke content ko utha kr ek file me save kr diya jata hai .
• ye .i file hoti hai 
• .i file me preprocess output hota hai.

Comments:- Aise code jo excute n ho vo comment kahlate hai

                        agr kisi line ke starting me '/' laga de to vo line excute nhi hoti hai

2) Compilation:- 

• assambly level instructiion me convert kiya jata hai
• yah .i file ko .s file me save krta hai

3) Assambly :- 

• .s file ko machine level instruction me convert kiya jata hai.
• yah .o file hoti hai aur ye machine level instruction hai

4)Linking :-

• Linker sari .o file ko combine kr ke ek excutive bana deta hai
• linker 2 trh ke hote hai :                                                                                                                        i)Static linking   ii)Dynamic linking 

(5) Loading) :- Linking ke bad RAM me load hota hai phir vaha se Run krta hai
