sscanf是C语言标准库中的一个函数,也可以在C++中使用,它允许从格式化字符串中提取数据。 cpp #include <cstdio> #include <iostream> #include <string> int main() { std::string str = "12345"; int num; if (sscanf(str.c_str(), "%d", &num) == 1) { std::cou...
); } // Output: -105 try { int m = Int32.Parse("abc"); } catch (FormatException e) { Console.WriteLine(e.Message); } // Output: Input string was not in a correct format. const string inputString = "abc"; if (Int32.TryParse(inputString, out int numValue)) { Console....
we define a variable namednumand initialize it with 0. Then, for each character in the input string, we multiply thenumvariable with 10, convert the character into its ASCII code, subtract the ASCII code value of ‘0’ and store the result back into thenumvariable. ...
