There's a nonstandard function: char *string = itoa(numberToConvert, 10); // assuming you want a base-10 representation Edit: it seems you want some algorithm to do this. Here's how in base-10: #include <stdio.h> #define STRINGIFY(x) #x #define INTMIN_STR STRINGIFY(INT_MIN) ...

Implement atoi to convert a string to an integer. Hint: Carefully consider all possible input cases. 官方难度: Easy 翻译: 实现atoi功能,将一个字符串转化成一个整数。 提示:仔细考虑各种可能出现的情况。 补充资料: 所谓atoi,是C语言库中的一个函数,其功能如下: ...
Convert string to integer Parses the C-stringstrinterpreting its content as an integral number, which is returned as a value of typeint. The function first discards as many whitespace characters (as inisspace) as necessary until the first non-whitespace character is found. Then, starting from ...
