Question

C++ question.

Introduce a vector of integers that return the biggest value of that vector.

Answer 1

#include <iostream>
#include <vector>

using namespace std;

int biggest(vector<int> v) {
    int max = v[0]; // set first element of vector as maximum element
    for (int i = 0; i < v.size(); ++i) {    // then, go through all elements of vector
        if (v[i] > max) {   // if element is greater than the maximum element found till now
            max = v[i]; // then update max
        }
    }
    return max; // finally return the maximum element found in the vector
}

void printVector(vector<int> v) {
    cout << "Vector is ";
    for (size_t i = 0; i < v.size(); i++) { // go through all elements of vector
        cout << v[i] << " ";    // print element
    }
    cout << endl;   // finally print a new line
}

int main() {
    vector<int> v = {1, 4, 9, 16, 9, 7, 4, 9, 11};  // create a vector
    printVector(v); // print the vector
    cout << "Largest value in vector is " << biggest(v) << endl;    // find and print biggest element in vector
    return 0;
