string的本质也是char类型数组,所以它可以如下写 std::stringa{"mayinshuang"}; std::cout<<a[0]<<std::endl; 1. 2. 两个字符串比较 std::stringa{"shuang"}; std::stringb{"shuang"}; std::cout<<std::boolalpha<<(a==b)<<std::endl; 1. 2. 3. 也可以使用compare比较,但是这返回的是int...
The character equivalent of 00 is \0. What you are trying to do is treat binary values as chars and that isn't going to work out well if the data isn't printable characters. If you are trying to take a string that is saved in a binary file then you first need to kno...

funcAppendsTest(){sli:=[]string{"a","b","c"}sli=append(sli)} 最开始我甚至不知道这种情况竟然可以编译通过,也不清楚如何为vet新增一个分析项。不过凭借一腔热情,通过分析源码,检索资料,询问ChatGPT后,几个小时后的第二天凌晨,就实现了初版功能。但后来的集成&修改较大,在此做相关记述。

String arrays and cell arrays of character vectors have compatible sizes if, for each dimension, one of these conditions is true: The lengths of that dimension are equal for all arrays. For one or more arrays, the length of that dimension is equal to 1. For the other arrays, the lengths...
