Compilation of C/C++ program By: Er. Aman Kumar

• It envolves following steps : – Creation of program– Compilation program– Linking with another modules from C library– loading program into computer memory

Creation the program

• First of all, we will create our program. This is known as source Code.

• Source code is user understandable and it is not computer understandable.

Compiling the program

• source code is then translated into object code using compiler. Source code acts as an input to compiler and object code is output.

Linking of program

• Linker-> is program that combines separately written modules into one program(file)

• C/c++ has given you some inbuilt function/classes that will be linked to your program using linker.

• Linker simply refers to creation of single file from multiple object files.

Loading of Program

• Loader simply loads the linked object file into memory for execution

Time taken during these steps

• Compilation Time : Time taken by compiler to convert source code into object code.

• Run Time : time taken by program for its execution
