The \n escape sequence allows for shorter code by specifying the newline in the string literal, and for faster runtime by eliminating the text formatting operation. Also, the compiler can map the escape sequence to a character encoding system other than ASCII and thus make the code more portable.
In C and C++, return exp; (where exp is an expression) is a statement that tells a function to return execution of the program to the calling function, and report the value of exp. If a function has the return type void , the return statement can be used without a value, in which case the program just breaks out of the current function and ...
The C standard defines return values 0 and EXIT_SUCCESS as indicating success and EXIT_FAILURE as indicating failure. (EXIT_SUCCESS and EXIT_FAILURE are defined in <stdlib.h>). Other return values have implementation-defined meanings; for example, under Linux a program killed by a signal yields a return code of the numerical value of the signal ...
According to the C99 specification and newer, the main function (unlike any other function) will implicitly return a value of 0 upon reaching the } that terminates the function. [c] The return value of 0 is interpreted by the run-time system as an exit code indicating successful execution of the function. [37]
In many languages (such as C, which introduced this notation), this is not a separate escape sequence, but an octal escape sequence with a single octal digit 0; as a consequence, \0 must not be followed by any of the digits 0 through 7; otherwise it is interpreted as the start of a longer octal escape sequence.

The title refers to "Return 0", which means that a program will successfully execute its intention or plan. According to Nielsen Media Research, the episode was seen by an estimated 6.51 million household viewers and gained a 1.0/4 ratings share among adults aged 18–49. The episode received universal acclaim from critics and fans, who praised ...
On Unix-like systems these are equal to 0 and 1 respectively. [3] A C program may also use the exit() function specifying the integer status or exit macro as the first parameter. The return value from main is passed to the exit function, which for values zero, EXIT_SUCCESS or EXIT_FAILURE may translate it to "an implementation defined form" of ...
Moreover, in C++ (and later versions of C) equality operations, with the exception of the three-way comparison operator, yield bool type values which are conceptually a single bit (1 or 0) and as such do not properly belong in "bitwise" operations.
