« Last post by asim roy on September 16, 2023, 11:56:29 am »A character with a value of zero which is why it is specified as a string rather than a random block of characters. This terminator tells the programmer where the text string ends so it is clear where the loop should stop processing since text data can be of almost any length. In code anything enclosed in double quotes like this will generate into a string expression followed by a character array of terminators. Take this classic example Hello world! This expression in generates a pointer to a character array containing the text message above consisting of all individual characters followed by an implicit terminator.
Since the expression returns a pointer to the first character you can store the memory location of the message like this Programming Languages Top Courses Hello Phone Number List World! If you declare it as above the contents of the string will be read-only. Any attempt to write to it may result in undefined behavior. Or worse your program might crash. Since the goal of string concatenation is to combine two or more strings together we want to be able to write strings freely. Instead if we declare it like this Hello world! Then the contents of our string will be writable. In this case the type of is a fixed-length array of characters characters plus the terminator not a pointer to a character as in the other examples above.

Note that once a string is declared this way you can later assign a pointer to its memory location and still write to it using pointer operations. This is because the pointer points to a writable location in memory. . Previously we just told to allocate a pointer to a fixed set of data. we tell to allocate some space on the stack for the string. With all of this done how do we combine two or more strings together Another very important question is about memory space.
