Question

C++ Question!

Write a function

vector concatenateMyVectors(const vector& v, const vector& w)

which returns the concatenation of the two vectors.

Answer 1

Please note that given method have error as vector required the type of date for creating vector

i have used template that can help to create any type of vector tested with int

save below code as concatvector.cpp or any name required ending with .cpp

i have also added main for testing if not required then skip the main function

#include <iostream>
#include <vector>

using namespace std;

// used template for generic type
template <typename Type>
vector<Type> concatenateMyVectors(const vector<Type> &v, const vector<Type> &w)
{

    vector<Type> out;
    // iterating first vector
     for (auto i = v.begin(); i != v.end(); ++i)
        out.push_back(*i) ;
    // iterating another vector
    for (auto i = w.begin(); i != w.end(); ++i)
        out.push_back(*i) ;
    // returning concanetaed vector
    return out;
}


// main for testing above function > start
int main(int argc, char const *argv[])
{
    vector<int> v, w, concat_v;
    v.push_back(2);
    v.push_back(4);
    
    w.push_back(45);
    cout<<"Concatenating vectors...."<<endl;
    concat_v = concatenateMyVectors(v, w);
    cout<<"Concatenated vectors...."<<endl;
    for (auto i = concat_v.begin(); i != concat_v.end(); ++i)
        cout << *i << " ";
    cout<<endl;
    return 0;
}
// main function end

// OUT

Concatenating vectors....
Concatenated vectors....
