|>What ANSI C says about: |>i = atoi(NULL);. ANSI says nothing specifically about this. It defines atoi as taking a pointer to a string. This means 

In this article, we will see the atoi implementation in c and its important features. So let us see the atoi implementation in C with examples code, Syntax of atoi function: In this C programming tutorial, we will learn three different functions of C : atof(),atoi() and atol(). These functions are mainly used to convert a string to other different data types. These functions are mainly used to convert a string to other different data types. Description The atoi () function converts a character string to an integer value. The input string is a sequence of characters that can be interpreted as a numeric value of the specified return type. The function stops reading the input string at the first character that it cannot recognize as part of a number.

See xlocale for more information. If str does not point to a valid C-string, or if the converted value would be out of the range of values representable by a double, it causes undefined behavior.

White-spaces are discarded until the first non-whitespace character is found.

The C library function int atoi (const char *str) converts the string argument str to an integer (type int).

It takes a string as an argument and returns an equivalent integer value. For example, the string “1234” will be converted to 1234.

The function atoi is a C standard library function that converts strings to numbers (more specifically, integers). PARAMETERS const char *str The function receives one parameter, a string. Note that the string is received as a constant - the function atoi will never alter a received string; only return its converted integer value.
