Question

Write a function called read floats(int n) that reads n float values from the user into an array and return the array back to the caller. Recall that a regular array will get deallocated when the function returns. (C++ the simplier the better)

Answer 1

#include <iostream>

using namespace std;

float *read_floats(int n);

int main() {
    float *arr = read_floats(5);
    for (int i = 0; i < 5; ++i) {
        cout << arr[i] << " ";
    }
    cout << endl;
    delete[] arr;
    return 0;
}

float *read_floats(int n) {
    cout << "Enter " << n << " numbers: ";  // ask for n numbers
    float *arr = new float[n];  // create a dynamic array, so that it can be returned
    for (int i = 0; i < n; ++i) {   // loop n times
        cin >> arr[i];  // read and store a number
    }
    return arr; // return the array
}
