In C programming, line splicing is the process of concatenating two or more physical lines of source code into a single logical line of code. This can be achieved by ending a line of code with a backslash \ character.
Here's an example of a C program that uses line splicing to declare a long string:
When the program is run, it will output "This is a very long string that spans across multiple lines in the source code"
The backslash \ at the end of the first line tells the compiler to treat the next line as a continuation of the current line.
It's useful in situations when a string or a command is too long to fit in a single line, it makes the code more readable and easier to manage.
It is important to note that this feature is only available in the preprocessing phase of the C compiler and the backslash and the newline characters are removed after preprocessing and do not appear in the compiled program.
It's important to take care when using line splicing feature and make sure that the backslash is the last character on the line, otherwise, it will cause a compile-time error.
