If Statement

Question

Why cant we use && in our if statement condition? Like if (var && var2 == 20) so we dont need to use more complex syntax.

Answer 1

Because the precedence of the logical operators are lower than the precedence of the comparison operators.

I think that supporting var && var2 == 20 to be checked as var == 20 && var2 == 20 would cause even more problems.

You can anyways define an additional function to support that logic.
bool NewAnd(int x, int y, int z)
{return x == z and y == z;}

if (NewAnd(var, var2, 20))
