This struct encapsulates information about an individual, with attributes including name and surname as strings and age as an integer. In the main function, we set a constant expression NUM to the value 3. This will be used as the desired number of instances when initializing the vector. The...

std map是STL的一个关联容器,它提供一对一(其中第一个可以称为关键字,每个关键字只能在map中出现一次,第二个可能称为该关键字的值)的数据处理能力,由于这个特性,它完成有可能在我们处理一对一数据的时候,在编程上提供快速通道。这里说下std map内部数据的组织,std map内部自建一颗红黑树(一种非严格意义上的平衡...
Then create a vector of strings where the strings are determined by a letter of the user's choosing. For example if the user chose the letter "e" your program should create and print the following strings: "I love", "e", "ating all kinds of de", "sse", "rts." ...

I have a structure with a vector of strings inside. I basically want a way to assign the different strings in the vectors different properties. I'm currently have an owners (a struct) that each own a vector of cats (vector<string> cat) For example, currently, I have working: Scarlett....
