The string can contain additional characters after those that form the integral number, which are ignored and have no effect on the behavior of this function. If the first sequence of non-whitespace characters in str is not a valid integral number, or if no such sequence exists because either...
(本章节中例子都是用 VS2005 编译调试的) 字符串转整形 • 形式: char *_itoa( int value, char *string, int radix ); • 参数: • value • string • radix 字符串转成 double 型 • 形式: double atof( const char *string ); • 参数: string 字符串转成 in ...
Implement the myAtoi(string s) function, which converts a string to a 32-bit signed integer (similar to C/C++'s atoi function). The algorithm for myAtoi(string s) is as follows: Read in and ignore any leading whitespace. Check if the next character (if not already at the end of th...
