CONCATENATE

38) C PROGRAM TO CONCATENATE OF TWO STRING

 LOGIC:- Take any two strings,either directly or by user.Now for concatenate there are many ways which is shown in example.

EXAMPLE 1 :- BY USING STRCAT() BUILT-IN FUNCTION


EXAMPLE 2 :- WITHOUT USING BUILT-IN FUNCTION


 EXPLANATION:- This program also created by using a function in which we apply the same logic.Here We use a for loop it can be done by using while loop also.In first for loop all character of string is assign in new string s3.So similarly we can assign the all characters of string s2 in string s3,But here is a problem if we try similar way then only string s2 is present in string s3 so to solve this problem the for loop is start with the size of s1 and run it atleast the size of s2 is not come.

EXAMPLE 3 :- BY USING POINTER 

 New Things:- this time we can take the string from user

Static Memory Allocation

Statement are of two types:- Declaration:- in which we declare the variable Action:- in which for,if-else,getch,printf,scanf etc are used. SMA(STATIC MEMORY ALLOCATION):-                                whenever we create a program,there is a line of declaration statement(or data type declarartion statement) such as int a;char b;etc. Due to this statement we create a variable a,now this variable is the example of SMA.SMA means how much memory is consumed by variable at the time of compiler,this decision is taken before the compilation. At the compile time these variable such as a and b does not having a memory.Memory is given when program is run i.e when object file convert into .exe file.But when program is run how much memory is taken by the variable is decided at the compilation time.This is known as SMA(Static Memory Allocation).

Compilation Process in C

Compilation The conversion of source code into object code is known as compilation.This process is done with the help of compiler. below is a full diagram of showing how source code convert into software(i.e software development in c) Explanation:- Source code :- the c programming coding is known as source code. save your programe with .c extension then your file become source file for example in fig: sum.c is a source file in which source code is written to print a hello. Prerocessor :- first we need a preprocessor software to convert source file (i.e .c file).Preprocessor handle all those statement which is starting from # symbol. Header file :-  In our programe as seen clearly in sum.c we did not create any header file (i.e which start from # symbol) we just use it.Preprocessor add the content of header file in our source file and creates a new file this file same as our source file but only difference is that the header file removed from the new file which ...

C PREPROCESSOR

DEF:- The C Preprocessor or cpp is the macro processor for the C and C++ programming language.It provide the ability for the inclusion of header file, macro expansion ,conditional compilation( #if,#ifdef,#ifndef,#else,#elif,#endif ) and line control. NOTE:- preprocessor directive are executed before compilation.All preprocessor directive starts with the # hash-symbol. There any many preprocessor directives in c language.In the figure there are two #if written. 1)#include:- The #include preprocessor directive is used to paste code of given file into current file. It is used include system-defined and user-defined header files. If included file is not found, compiler renders error. By the use of #include directive, we provide information to the preprocessor where to look for the header files. There are two variants to use #include directive. (a) #include <filename> :- The #include <filename> tells the compiler to look for the directory where system header file...
