Assume you define a vector in the following way: vector vec;

Assign the value 10 to the first element of this vector. What is the statement you would use?

vec[0].push_back(10)

Explanation:

Given

Declaration: vector <int> vec

Required

Assign 10 to the first element

This can be done using the push_back keyword.

The syntax is:     vectorname[position].push_back(value);

In this case:

vectorname = vec

position = 0 i.e. first element

value = 10

So, we have:

vec[0].push_back(10)

the correct answer is "part of speech" if the portion used is "verb, noun" there is another question similar to this with the same question but different portion. the other portion is "hand write" and the correct component for that question is "antonym".

hope this . : )
