5 Functions

Beginner

This function takes 2 integers and returns their sum as an integer. Please note explicit returns are not required i.e last expression will be returned as the value. Here in this function we can see that cangjie can infer the return type.

Function call is what you’d expect.

functions.cj

func plus(a: Int64, b: Int64): Int64 {
    a + b
}

// Return type can be inferred:
func plusPlus(a: Int64, b: Int64, c: Int64) {
    a + b + c
}

main() {
    var res = plus(1, 2)
    println("1 + 2 = ${res}")
    res = plusPlus(1, 2, 3)
    println("1 + 2 + 3 = ${res}")
}

// Output:
// 1 + 2 = 3
// 1 + 2 + 3 = 6
