convert a string to an unsigned long integer(把输入的字符串转换成数字). strtoul() 会扫描参数nptr 字符串,跳过前面的空白字符(例如空格,tab缩进等,可以通过isspace() 函数来检测),直到遇上数字或正负符号才开始做转换,再遇到非数字或字符串结束时('\0')结束转换,并将结果返回。 三、所需头文件: #include...

你也可以考虑使用_tcstoul()或者_tcstol(),它们都能把字符串转化成任意进制的长整数(如二进制、八进制、十进制或十六进制),不同点在于前者转化后的数据是无符号的(unsigned),而后者相反。 所以直接使用函数_ttoi就可以了。 CString类相应函数: CString类 一、常用成员函数 1.int GetLength( ) const; 说明:获取C...
