Can I use line assignment and compilation?

If I have:

#include <string>

std::string myString = "Hello";

then do either:

myString = "Hello World";

or

myString+= " World";

Can I risk writing some other memory? Do I need to use string functions to add or resize a string?

C std::string, which is completely excellent because it std::stringmanages its own memory.

With c-style strings using char*you need to manage your own memory.

std is like any other container class, such as a vector. They also have an adjacent memory structure, and when they need extra space, they simply redistribute the memory for themselves.

Using stringit gives you the luxury of processing it, like other primitive data types, for example int float, etc.

int a = 3;It can be done without <vreda> a = 5ora += 3

Same goes for

string myString = "Hello";

myString = "Hello World";

myString+= " World";
