Basically I have an assignment where I can't use if() or if else statements in C++.

The problem is saying :
If the entered number is greater than 2.375, make it = 2.375
If the number is less than 0, make it =0.

How do I do this without if functions? I'm just newbie learning C++ :3

What I have tried:

I so far cannot think of anything I've learned yet that can do this. Any help would be appreciated!

Couple of ways:
1) The ternary operator:

C++

value = value > 0 ? value : 0;

But ... technically, that;s a short form of if ... else ...
2) Cheat, and use a while:

C++

while (value < 0) value = 0;

It's not an efficient solution, but ... it works.
3) Cheat even less efficiently and use a for:

C++

for ( ; value < 0; ) value = 0;
