How to Convert a Vector of Floats to a Vector of Strings in C++ - Step by Step Examples

How to Convert a Vector of Floats to a Vector of Strings in C++ ?

Answer

To convert a vector of floats to a vector of strings in C++, you can use the `std::to_string()` function along with the `std::transform()` algorithm.

✐ Examples

1 Convert Vector of Floats to Vector of Strings

In this example,

We create a vector of floats named floatVector.
We create an empty vector of strings named strVector.
We use the std::transform() algorithm to apply the std::to_string() function to each element of floatVector and store the result in strVector.

C++ Program

#include <iostream>
#include <vector>
#include <algorithm>
#include <string>

int main() {
    std::vector<float> floatVector = {1.5, 2.5, 3.5, 4.5, 5.5};
    std::vector<std::string> strVector;
    strVector.reserve(floatVector.size());
    std::transform(floatVector.begin(), floatVector.end(), std::back_inserter(strVector), [](float f) { return std::to_string(f); });
    for (const auto& str : strVector) {
        std::cout << str << " ";
    }
    return 0;
}

Output

1.5 2.5 3.5 4.5 5.5
