f++ example

Examples of ? being used with f++:

int a = 15, b = 10
int max = ?(a > b; $[a]; $[b])

console(max)

int a = 15, b = 10

`?(a > b; a; b) := 20`
console(a)

n++ example

Examples of ? being used with n++:

@int(a = 15, b = 10)
@int(max = ?(a > b; $[a]; $[b]))

@console(max)

@int(a = 15, b = 10)

@`@?(a > b; a; b) := 20`
@console(a)

@exprtk(?(a > b; a; b) := 30)
@console(a)
