Push and print elements in a float vector

In this example, we are declaring a float vector and pushing the elements using push_back() function with the 5 float values and then printing the value separated by space.

Example

#include <iostream>
#include <vector>  //for vector
using namespace std;

int main() {
  // vector  for float elements
  vector<float> v1;

  // adding 5 elements
  v1.push_back(10.20f);
  v1.push_back(89.30f);
  v1.push_back(12.11f);
  v1.push_back(33.33f);
  v1.push_back(22.19f);

  // print all elements
  cout << "vector elements are: ";
  for (int i = 0; i < v1.size(); ++i) {
    cout << v1[i] << ' ';
  }
  cout << endl;

  return 0;
}

Output

vector elements are: 10.2 89.3 12.11 33.33 22.19
