Functions
Functions ,Just like in other programming languages, is a piece of code which performs an action that can be used repeatedly.
fn main(){
println!("Hello world!");
}Here main is a function
Macros
Macros are built in functions that help you do specific tasks
fn main(){
println!("Hello world!");
}
Here println is a macro - we can identify macros with ! sign after macro name.
println! vs print!
println! macro adds a new line to the output but !print doesn’t.
So println! is prefered over !print
