C++ Standard Template Library in Practice - Replacing and Transforming - equals

The video tutorial introduces the concept of standard transform, which allows for dynamic replacements in data sets using unary and binary operators. It contrasts standard transform with standard for each, highlighting that transform does not make in-place changes or guarantee in-order application. The tutorial provides example code demonstrating string transformation to lowercase and vector combination using the sum operator. The video concludes with a preview of upcoming topics on swapping and rotating.

What is the main advantage of using standard transform over standard replace functions?

• It allows for dynamic replacements using callable objects.

• It can replace multiple values at once.

• It modifies the data source directly.

• It guarantees in-order application of operations.

Which operator signature is required for a unary operation in standard transform?

• It takes two constant type references and returns a value.

• It modifies the data source directly.

• It takes a single constant type reference and returns a value.

• It guarantees in-order application of operations.

What should you use if you need to apply a function to a sequence in order?

• Standard replace

• Standard sort

• Standard for each

• Standard transform

In the example code, what is the purpose of using a lambda function?

• To modify the data source directly.

• To convert characters to uppercase.

• To apply a custom operation to each element.

• To guarantee in-order processing.

What is the result of combining two vectors using standard transform in the example?

• The vectors are sorted.

• The vectors are concatenated.

• The vectors are multiplied element-wise.

• The vectors are summed element-wise.
