c++ fmt70 fmtformat vector

In C++, fmt7.0 library provides a powerful and efficient formatting library that supports various types of string formatting. One of the key features of fmt7.0 is the fmt::format function, which allows you to format strings using placeholders.

To use fmt7.0 and fmt::format, you need to include the appropriate header file:

#include <fmt/format.h>

You can then use the fmt::format function to format strings. Here's an example that demonstrates how to format a string with placeholders and a vector of values:

#include <fmt/format.h>
#include <vector>

int main() {
  std::vector<int> numbers = {1, 2, 3, 4, 5};
  std::string formattedString = fmt::format("Numbers: {0}, {1}, {2}, {3}, {4}",
                                            numbers[0], numbers[1], numbers[2], numbers[3], numbers[4]);
  std::cout << formattedString << std::endl;
  
  return 0;
}

In the above example, we have a vector of integers named "numbers". We use the fmt::format function to create a formatted string with placeholders ({0}, {1}, {2}, {3}, and {4}). We pass the values from the vector to the placeholders in the same order.

The resulting formatted string is then printed to the console using std::cout.

Output:

Numbers: 1, 2, 3, 4, 5

This is just a basic example, and fmt7.0 provides many more formatting options and features. You can refer to the fmt documentation for more information on how to use fmt::format and other formatting capabilities provided by the library
