Question

What are vectors in C++?

Answer 1

Vectors are like arrays, but they can change in size.
Also there are some advanced methods of vectors, such as empty (whether the vector is empty), erase (clear the vector), insert (insert element at specified position (next elements are shifted), push_back, (add element to the end) pop_back (delete the last element), swap (swap contents of two vectors), etc.

Answer 3

Vectors are a part of Standard template library(STL). Vector is a sequence container which resize automatically when element insert or remove. It's store elements in contiguous memory locations.

If you want to use vector in c++ then you have to add #include <vector> header file in code.

Declares a vector of integers

std:: vector<int> v;

Answer 4

Hello dear Jinasena
Vectors are widely used in artificial intelligence and are a kind of dynamic memory that doubles in length if its memory is full.
I hope you understand.

Answer 5

#include <iostream>
using namespace std;
void calutale equation on result ( float a, float b, float c, float d, float x );
void max result ( float sp1, float sp2, float sp3 );
main()
{
char sp;
calculate equation result\( 2, 3, 4, 5, 10 );
do
cout<<"\n do you to enter more data (y for yes n for no) : " ;
cin>> sp;
if (sp=='y' || sp=='y')
calulate equation on result (6, 7, 8, 9, 11 );
else
break;
} while ( sp=='y' || sp=='y' )

}

void calulate equation on result ( float a, float b, float c, float d, float x)
{
float sp1, float sp2, float sp3;
sp1= x+b/ (3*a);
sp2=(3*a*c-(b*b)) / ( 3* (a*a));
sp3=( 2*( b*b*b)-9* (a+b+c)+27* (a*a) *d) /
cout<<" spot 1: "<< sp1 <<endl;
cout<<" spot 2: "<< sp2 <<endl;
cout<<" spot 3: "<< sp3 <<endl;

max result ( sp1, sp2, sp3 ); // function call
}
void max result ( float sp1, float sp2, float sp3 )
{
if (sp1 > sp 2 && sp1 > sp3 )
cout <<"\ spot 1 result is maxium";
else if ( sp2> sp1 && sp2 > sp3)
cout <<"\ spot 2 result is maxium";
else
cout <<"\ spot 3 result

Kaung Set Min Soe,
1. Read the answers.
2. Please, answer questions like this only if you know the answer and its meaning is at least somewhat different from what others wrote in their answers (if you are not the first to answer), otherwise your answer is most likely to be considered as spam (either not an actual answer or repeating the same answer). Exceptions are when a question is (or a duscussion in answers has moved to) open-ended (examples of such topics are personal experience, bugs (in computing terms), complaint).
If you have the same question or relate to a problem described in it, then upvoting that question (and answers that helped you with it if such exist) is enough. You can also press the star at the bottom left of the question if it is not highlighted already to receive notifications when someone answers, so that you can read them before you answer yourself this question again.
