rustHow do I delete a character from a Rust string?
You can delete a character from a Rust string using the .remove(start_index)
method. This method takes the index of the character to be removed as an argument.
For example:
let mut my_string = String::from("Hello World!");
my_string.remove(6);
println!("{}", my_string);
This will output HelloWold!
.
The code works as follows:
let mut my_string = String::from("Hello World!");
: This creates a mutable string with the valueHello World!
.my_string.remove(6);
: This calls theremove
method on the string, passing in the index of the character to be removed (in this case, 6, which is the space betweenHello
andWorld
).println!("{}", my_string);
: This prints the modified string to the console.
For more information, see the Rust documentation on strings.
