let a : int32 = 100 let b : int32 = 200 (* check the boolean condition using if statement *) if (a = 100) then (* if condition is true then check the following *) if (b = 200) then printfn "Value of a is 100 and b is 200\n" printfn "Exact value of a is: %d" a printfn "Exact value of b is: %d" b
編譯和執(zhí)行程序時,將產生以下輸出
Value of a is 100 and b is 200 Exact value of a is: 100 Exact value of b is: 200
