swift - Function call is requiring an argument but the function takes no arguments -


i have code in file called makerequest.swift in class makerequest:

class makerequest {     func callapi () {         let url = nsurl(string: "http://apiserver.com)          let task = nsurlsession.sharedsession().datataskwithurl(url!) {(data, response, error) in             println(nsstring(data: data, encoding: nsutf8stringencoding))         }          task.resume()     } }

and call makerequest.callapi(). however, requiring argument:

missing argument parameter #1 in call

when tried configure callapi take string:

class makerequest {     func callapi(urlend: string) {         ...     } }

and call with

makerequest.callapi("ending")

it errors with

cannot invoke 'callapi' argument list type of '(string)'

sorry how confusing swift's error messages are. (there cool reason nature of error message, never mind right now.) problem calling method class method declared instance method.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
