Adding Integer Numbers
Let’s see how to compute the sum of two integer numbers ; for example, 80 and 34.
Put the following line as the only contents of the braces of the main function:
print!("The sum is {}.", 80 + 34);
The execution will print: "The sum is 114.".
The second argument of the print macro is the expression 80 + 34.
The compiler surely does not store in the executable such numbers ...
