get part of string c++

To get a part of a string in C++, you can use the substr() function. Here's how it works:

1. Declare a string variable and assign a value to it.
2. Use the substr() function to extract a part of the string. Pass the starting position and the length of the substring as arguments to the substr() function.
3. Store the extracted substring in a new string variable or use it as needed.

That's it! This is how you can get a part of a string in C++ using the substr() function.
