C++ string formatting like Python "{}".format
Try this https://github.com/fmtlib/fmt
fmt::printf("Hello, %s!", "world"); // uses printf format string syntax
std::string s = fmt::format("{0}{1}{0}", "abra", "cad");
In C++20 you'll be able to use std::format
which brings Python-like formatting to C++:
auto s = std::format("{:10}", "some_string");
Until then you can use the open-source {fmt} formatting library, std::format
is based on.
Disclaimer: I'm the author of {fmt} and C++20 std::format
.
You have many options here. For instance using streams.
source.cpp
std::ostringstream stream;
stream << "substring";
std::string new_string = stream.str();
