我如何连接两个std::vector?
std::vector
c++ stl vector concatenation stdvector
C++ std :: vector和std :: basic_string之间的根本区别是什么?
c++ string vector
假设
b = ["good ", "bad "] a = ["apple","mango"] then output = ["good apple","good mango","bad apple","bad mango"]
我知道这可以用嵌套的for循环来完成,但是使用C++ STL是否有一些优雅的衬里呢?
c++ string stl vector
c++ ×3
vector ×3
stl ×2
string ×2
concatenation ×1
stdvector ×1
