What are vector operations in C++?

What are vector operations in C++?

Vector operations in C++ refer to the various functions and methods that can be performed on vectors, such as addition, subtraction, and scalar multiplication.

Can you give me an example of adding two vectors?

Sure! To add two vectors in C++, you can use the following code:

#include <iostream>
#include <vector>

std::vector<int> addVectors(const std::vector<int>& v1, const std::vector<int>& v2) {
    std::vector<int> result;
    for (size_t i = 0; i < v1.size(); ++i) {
        result.push_back(v1[i] + v2[i]);
    }
    return result;
}

What about subtracting vectors?

Subtracting vectors is similar to adding them. Here's an example:

std::vector<int> subtractVectors(const std::vector<int>& v1, const std::vector<int>& v2) {
    std::vector<int> result;
    for (size_t i = 0; i < v1.size(); ++i) {
        result.push_back(v1[i] - v2[i]);
    }
    return result;
}

How do I perform scalar multiplication on a vector?

You can perform scalar multiplication by multiplying each element of the vector by the scalar value. Here's an example:

std::vector<int> scalarMultiply(const std::vector<int>& v, int scalar) {
    std::vector<int> result;
    for (int value : v) {
        result.push_back(value * scalar);
    }
    return result;
}
