rustHow do you create a string with a variable in Rust?
Creating a string with a variable in Rust is a simple process. To do this, you must first declare a variable and assign it a value. Then, you can use the format!
macro to create a string with the variable.
let my_variable = "Hello World";
let my_string = format!("This is my variable: {}", my_variable);
println!("{}", my_string);
Output example
This is my variable: Hello World
The code above consists of three parts:
let my_variable = "Hello World";
- This declares a variable calledmy_variable
and assigns it the value"Hello World"
.let my_string = format!("This is my variable: {}", my_variable);
- This uses theformat!
macro to create a string with the value ofmy_variable
inserted into it. The{}
is a placeholder for the variable.println!("{}", my_string);
- This prints the string to the console.
