这句语句的意思是,pf就是一个指向函数的指针,其中该函数的参数是两个const string的引用,返回值是bool类型。 注意:*pf两边的括号必不可少。如果不写这个括号,则pf就是一个返回值为bool指针的函数了,大家可以对比上面的指针函数。 2、函数指针的定义方法: ...

基于C++11标准 标准库中定义了to_string(val),将val转换成string类型; stoi(s,p,b): 返回s起始子串(表示整数内容的字符串)的数值,返回值的类型为int。其中b表示转换所用的基数,默认为10(表示十进制)。p是size_t的指针,用来保存s中第一个非数值字符的下标,p默认为0,即函数不返回下标。
