Surprise in C lines, NULL, spaces

Question

In C, can I say that the space in the string is of type NULL or something else?
In C, which character represents the end of a string?

Answer 1

a null character (ASCII value 0, '\0'as a character literal) terminates a string in C. This character is usually not considered a space character.

The space in the middle of this line, for example: "Hello world"is a character with an ASCII value of 32. This is not the same as NULL or \0.
