- What is the difference between NULL, '\\0' and 0?What is the difference between NULL, ‘\0’ and 0. "null character (NUL)" is easiest to rule out. '\0' is a character literal. In C, it is implemented as int, so, it's the same as 0, which is of INT_TYPE_SIZE. In C++, character literal is implemented as char, which is 1 byte. This is normally different from NULL or 0.
- boolean - In JavaScript, why is "0" equal to false, but when tested by ...So string zero "0" is converted to Number data type and boolean false is converted to Number 0. So "0" == false // true. Same applies to ` false == "0" //true === Strict equality check evaluates the arguments with the original data type "0" === false // false, because "0" is a string and false is boolean. Same applies to . false === "0 ...
- c - What do 0LL or 0x0UL mean? - Stack OverflowLL designates a literal as a long long and UL designates one as unsigned long and 0x0 is hexadecimal for 0. So 0LL and 0x0UL are an equivalent number but different datatypes; the former is a long long and the latter is an unsigned long. There are many of these specifiers: 1F // float. 1L // long.
- factorial - Why does 0! = 1? - Mathematics Stack ExchangeThus 0! = 1. The theorem that (n k) = n! k! (n − k)! already assumes 0! is defined to be 1. Otherwise this would be restricted to 0
- c++ - What does '\0' mean? - Stack OverflowThe \0 is treated as NULL Character. It is used to mark the end of the string in C. In C, string is a pointer pointing to array of characters with \0 at the end. So following will be valid representation of strings in C. char *c =”Hello”; // it is actually Hello\0. char c[] = {‘Y’,’o’,’\0′}; The applications of ‘\0’ lies in ...
