1 Convert List of Strings to List of Floats

In this example,

We have a list of strings named string_list.
We iterate over each string in the list and use the std::stof() function to parse each string as a float.
The result is a list of floats.

C++ Program

#include <iostream>
#include <list>
#include <string>

int main() {
    std::list<std::string> string_list = {"1.1", "2.2", "3.3", "4.4", "5.5"};
    std::list<float> float_list;
    for (const auto& str : string_list) {
        float_list.push_back(std::stof(str));
    }
    for (const auto& num : float_list) {
        std::cout << num << " ";
    }
    return 0;
}

Output

1.1 2.2 3.3 4.4 5.5
