If I need to null-terminate a String, should I rather use \0 or is a simple 0 also enough?
Is there any difference between using
char a[5];
a[0] = 0;
and
char a[5];
a[0] = '\0';
Or is \0 just preferred to make it clear that I'm null-terminating here, but for the compiler it is the same?

In programming languages/context, a null character is represented by the escape sequence \0, and it marks the end of a character string.
The null terminated strings are basically a sequence of characters, and the last element is one null character (denoted by '\0'). When we write some string using double quotes (“…”), then it is converted into null terminated strings by the compiler.
A "string" is really just an array of char s; a null-terminated string is one where a null character '\0' marks the end of the string (not necessarily the end of the array). All strings in code (delimited by double quotes "" ) are automatically null-terminated by the compiler.
\0 is just one more character from malloc and free perspective, they don't care what data you put in the memory.
'\0' is an escape sequence for an octal literal with the value of 0. So there is no difference between them
Side note: if you are dealing with strings than you should use a std::string.
