Question

1. Write a code to ask for a vector with 10 elements from the user and replace the 1^st, 3^rd, 8^th  to 9^th  elements with the second element of the given vector. (you can insert a vector when you use input function)

Answer 1

If you have any doubts, please give me comment...

#include<iostream>

#include<vector>

using namespace std;

void input(vector<int> &v){

    cout<<"Enter 10 values: ";

    int val;

    for(int i=0; i<10; i++){

        cin>>val;

        v.push_back(val);

    }

}

int main(){

    vector<int> v;

    input(v);

    cout<<"The entered vector data is:";

    for(int i=0; i<v.size(); i++){

        cout<<" "<<v[i];

    }

    cout<<"\n\nThe second element is: "<<v[1]<<endl;

    v[0] = v[1];

    v[2] = v[1];

    v[7] = v[1];

    v[8] = v[1];

    cout<<"\n\nAfter replacing with second element, the vector is:"<<endl;

    for(int i=0; i<v.size(); i++){

        cout<<v[i]<<" ";

    }

    cout<<endl;

    return 0;

}
