Question

TASK 1: [20] 

• Write a little program that creates a vector array of type doubles with 10 members (0…9) 

• Use a for loop to store the values i^2 in the vector for each index i 

• Also write code to display the content of the vector

• The output should be: 0, 1, 4, 9, 16, 25, 36, 49, 64, 81 

• Instead of using array access, try to use push_back, pop_back, etc. also, i.e. try being dynamic.

 

TASK 2: [20] 

• Generate random numbers between -1.0 and 1.0 

• Store these numbers in a vector 

• Play a bit with random and show us what you did

Answer 1

Q1)

c++ code:

#include <bits/stdc++.h>
using namespace std;

int main()
{
    vector<double>v;
    //push_back element in vector
    for(int i=0;i<10;i++)
    {
        v.push_back(i*i);
    }
    cout<<"Element of vector are:";
    for(int i=0;i<10;i++)
    {
        cout<<v[i]<<" ";
    }
    
return 0;
}
