Answer:

False

Explanation:

vector is like a dynamic array that has a special ability to resize automatically when it required.

vector has several functions:

like, insert() to insert the element in the vector.

delete() for delete the one element at a time.

empty() is also the function used in the vector. It is used for checking the vector is empty or not.

it gives the Boolean value (TRUE or FALSE), if the vector is empty it gives the output TRUE if the vector is not empty it gives the output FALSE.

It is not used for empty or deletes all elements of the vector.

Therefore, the answer is False.

mrs_skeptik [129]

Answer:

writing code for a software program.

Explanation:

Software development life cycle (SDLC) can be defined as a strategic process or methodology that defines the key steps or stages for creating and implementing high quality software applications.

Some of the models used in the software development life cycle (SDLC) are; waterfall model, incremental model, spiral model, agile model, big bang model, and V-shaped model.

The five (5) standard stages of development in software development are;

I. Analysis.

II. Design.

III. Implementation (coding).

IV. Testing.

V. Maintenance.

A typical day in programming and software development would involve writing code for a software program.

Generally, software applications or programs require a code containing series of sequential instruction to perform specific tasks, commands and processes. These sets of code are typically written by a software developer (programmer).

}

return;

}

}
