1st project Function calls from within a function (all 7)

7:23pm Mon 9th Sep, Johar K.

As the ml syntax outlines here, a function can have a statement which can be a function call: program-item: statement | function identifier ( identifier )* ←–tab–→ statement1 ←–tab–→ statement2 .... statement: identifier "<-" expression | print expression | return expression | functioncall So does this mean recursion is allowed or is this referring to calling other functions only?

The syntax of ml does seem to allow recursion, shouldn't be hard to implement (since you just copy the function call into C).

Surely this won't be tested though as it will always become an infinite loop since there's no base case

Yes, I forgot there are no "if" statements in ml, because there are no "if" statements, it would run forever. So, don't worry about recursion. Can't see the point in testing an infinite loop.

Where did you get this ml syntax from? I haven't seen this.

It's a link on the project description page
