Programs Are Translated by Other Programs into Different Forms

The Hello program begins life as a C program at a high level, because they understood people and can be read in this way. However hello.c run on the system, individual statements C should other programs in a sequence of instructions in machine language translate low level. Technical Data used in the field explained in computer courses in rawalpindi.
These commands are packaged in an executable form of a program referred object and stored as a binary disk. programs objects are also known as objects executable files. In a Unix system presentation of the translation from the source object file is executed by a compiler driver: Unix> gcc -o hello hello.c driver GCC compiler reads the source file hello.c here and translates it into an executable file object file
Hi. The translation is in the sequence of four phases, as shown in Figure 1.3. the programs
carrying the four phases (preprocessor, compiler, assembler and linker) are known collectively as purification system. Some more details of computer courses in Rawalpindi are as under

preliminary stage. The preprocessor (CPP) modified the original program C in accordance with the guidelines beginning with the # character. For example, the #include <stdio.h> command line 1
hello.c tells the preprocessor to expand the stdio.h header file system to read and Paste
directly in the program text. The result is another program in C, usually .i suffix.
• Creation phase. The compiler (CC1) hello.i translates the text file in text files hello.s,
It is containing a program in assembly language. Any statement in an assembly language program
accurately describes an instruction of machine-language low level in a standard text format. meeting
Language is useful because it provides a common language of origin for different compilers for different
The high-level languages. For example, C-compiler and Fortran compilers generate two output files
the same assembly language.
• Installation phase. Then the assembler (as) translates language instructions machine hello.s
them packaged in a form known as a moving object program, and stores the result in the object
hello.o file. The hello.o file is a binary file, whose bytes coding machine language instructions
instead of characters. If we are going to show a hello.owith text editor, which appears to be gibberish.
• linking phase. Please note that our program hello calls the printf function, which is a part of the standard
C library of any C compiler provided. Printf is located in a separate precompiled
printf.o called object file that must be somehow merged with our program hola.o. The linker (ld) treated this merger. The result is the hi-file is an executable object file (or simply executable), which is ready to be loaded and executed by the system memory.
