char range

Why is the char type in the following range? In C, the signed char type ranges from-128 ~ 127. This is also written in every textbook, but no book (including teachers) will give you why-128 ~ 127. It seems that this problem is easy and easy, so you

in C, the range of signed char types is -128~127, which is written in every textbook, but no book (including the teacher) will give you a -128~127, and the question seems simple and easy enough not to think about why, Is there a formula for an

  Ansi c provides three types of characters: Char, signed Char, and unsigned char. There are only two types of characters like short and INT (INT is unsigned int by default ). Each of the three occupies 1 byte. Therefore: The value range of signed

ANSI C provides 3 types of characters, namely Char, signed char, unsigned charChar is equivalent to signed char or unsigned char, but it depends on the compiler!These three character types are stored in 1 bytes and can hold 256 different values.The
