C++ Language:
Do not use namespace
Test Case:
Here is code:
#include <iostream>
#include <vector>
using std::vector;
vector<double> zipper_merge(vector<double> a, vector<double> b)
{
vector<double> result;
int i;
for (i = 0; i < a.size() && i < b.size(); i++)
{
result.push_back(a[i]);
result.push_back(b[i]);
}
if (i < a.size())
{
for (; i < a.size(); i++)
{
result.push_back(a[i]);
}
}
else if (i < b.size())
{
for (; i < b.size(); i++)
{
result.push_back(b[i]);
}
}
return result;
}
vector<char> zipper_merge(vector<char> a, vector<char> b)
{
vector<char> result;
int i;
for (i = 0; i < a.size() && i < b.size(); i++)
{
result.push_back(a[i]);
result.push_back(b[i]);
}
if (i < a.size())
{
for (; i < a.size(); i++)

}
}
else if (i < b.size())
{
for (; i < b.size(); i++)
{
result.push_back(b[i]);
}
}
return result;
}
void ASSERT_EQ(vector<double> a, vector<double> b)
{
for (int i = 0; i < b.size(); i++)
{
if (a[i] != b[i])
{
std::cout << "Test case failed!" << std::endl;
return;
}
}
std::cout << "Test case passed!" << std::endl;
}
void ASSERT_EQ(vector<char> a, vector<char> b)
{

}
}

}
int main()
{
const vector<double> a{1, 4, -6};
const vector<double> b{3, 6, 2};
const vector<double> expected{1, 3, 4, 6, -6, 2};

I need help writing this code in C++ Proj11.cpp is provided as well as the randomdata.txt thank you in advance! Objectives: The main objectives of this project is to introduce you to recursion, and test your ability to work with some STL functionalities. A review of your knowledge on working with templates, dynamic data structures, as well as manipulating dynamic memory, classes, pointers and iostream to all extents, is also included. Description: For the entirety of this project, you will...
In C++ please! *Do not use any other library functions(like strlen) than the one posted(<cstddef>) in the code below!* /** CS 150 C-Strings Follow the instructions on your handout to complete the requested function.

C++ / Visual Studio Implement the member function below that returns true if the given value is in the container, and false if not. Your code should use iterators so it works with any type of container and data. template< typename Value, class Container > bool member( const Value& val, const Container& cont ); just implement this function in the code below #include <iostream> #include <array> #include <deque> #include <list> #include <set> #include <string> #include <vector> using namespace std; #define...
Please use C++ and add comments to make it easier to read. Do the following: 1) Add a constructor with two parameters, one for the numerator, one for the denominator. If the parameter for the denominator is 0, set the denominator to 1 2) Add a function that overloads the < operator 3) Add a function that overloads the * operator 4) Modify the operator<< function so that if the numerator is equal to the denominator it just prints 1...
This is a C++ programming question. Please provide the correct, workable code. Use the following three programs to help solve the problem. Provide comments throughout the code. Problem to solve: Code 1: Complex.h #pragma once #ifndef COMPLEX_H #define COMPLEX_H class Complex { private: double real; double imag; public: // initialize the complex number to 0.0 Complex() : real(0.0), imag(0.0) {} // initialize the complex number at declaration or new Complex(double r, double i) :...

C++Language: The question is not allowed to use STL. Also, plz use noskipws and push_back for the question.The input is more than one, so the code should be able to run more than once Strings are vectors words on that line and the line itself. What's a word? It is a series of alphabetic characters, separated by whitespace other non-alphabetic characters. Write a program that reads from cin and tor each line, outputs number Pretty easy huh, well, you aren't...
