在C++中,字符串与整数的相互转换有多种方式。以下是主要的方法:从string到int的转换方法:使用atoi函数:atoi是C语言的函数,但在C++中仍然可以使用。示例代码:int num = atoi;使用strtol函数:strtol是一个更高级的选项,允许指定进制。示例代码:int num = strtol;使用stoi函数:stoi是C++11引入的...
public static void stringtoint(String s){ //判断字符串是否为null和是否为空 if(s == null || s.length() == 0) return; char[] temp = s.toCharArray();//可以不用 int sum = 0; int j = temp.length-1; int flag = 0; if(temp[0] >= '0' && temp[0] <= '9'){ int k = ...
int num = atoi(argv[1]); // Do something with num. return 0; }。 中文回答: stringtoint函数详解。 `stringtoint`函数是C++语言中用来将字符串表示的整数转换为对应的整数值的函数。它接受一个参数,该参数指向要转换的字符串。函数成功时返回整数值,失败时返回0。 `stringtoint`函数的语法如下所示: ...
