    #define

    Hi

    i have 4 expressions ( each of them have only one arithmetical operator (+,-,*,/) )

    a>b?a+b:b+a
    a>b?a-b:b-a
    a>b?a*b:b*a
    a>b?a/b:b/a

    Is there any way to write a general macro for this ? something like EXPR(X) where we could substitute X with +,-,*,/ .. or any alternate way to do this ?

    Thanks

    Code:
    #define EXPR(x, y, op)   ((x) > (y) ? (x) op (y) : (y) op (x))
    And then you call it:

    Code:
    var1 = EXPR(x, y, -);
    var2 = EXPR(x, y, /);
    ...
