请你来实现一个myAtoi(string s)函数,使其能将字符串转换成一个 32 位有符号整数(类似 C/C++ 中的atoi函数)。 函数myAtoi(string s)的算法如下: 读入字符串并丢弃无用的前导空格 检查下一个字符(假设还未到字符末尾)为正还是负号,读取该字符(如果有)。 确定最终结果是负数还是正数。 如果两者都不存在,则...
It returns a integer value of the parsed string.Example 1Following is the basic example for the basic conversion to demonstrate the string::stoi using C++.Open Compiler #include <iostream> #include <string> using namespace std; int main() { string s = "42"; int num = stoi(s); cout ...

(Convert String to Integer) In the C Programming Language, the atoi function converts a string to an integer.The atoi function skips all white-space characters at the beginning of the string, converts the subsequent characters as part of the number, and then stops when it encounters the ...
Theatoi()function converts a string into an integer in the C programming language.atoi()stands forASCII to Integer. Theatoi()function neglects all white spaces at the beginning of the string, converts the characters after the white spaces, and then stops when it reaches the first non-number...
