c - using nested printf statements giving strange output -


I recently came to this code and I am unable to understand how it works 

  is included in #lt; stdio.h & gt; Integer main () {printf ("line 1 \ n", printf ("line 2 \ n", printf ("line 3 \ n", printf ("row 4 \ n", 0)))); Return 0; }

This is giving the following output: 

  line 4 line 3 line 2 line 1

is used to print the formatted line. For example, to print an integer, you call: 

  printf ("% d", 1);

What you did, the argument to call the return value of Nest print is that it needs to first be nested call evaluation, which means that Is in. Your call is the same: 

  int temp; Temp = printf ("line 4 \ n", 0); Temp = printf ("line 3 \ n", floating); Temp = printf ("line 2 \ n", floating); Temp = printf ("line 1 \ n", floating); Also, note that since you have a format specifier in the format string, then there is no meaning for the second argument, and if your compiler is quite good then it is also more that. Will warn about.

ios - How do I use CFArrayRef in Swift? -

I am using Objective-class in my Swift Project through a bridging header. The method signature looks like this: - Some cement (some type) some parameters; I started by getting an example of class, calling method, and storing the value: var myInstance = MyClassWithThatMethod (); Var cfArr = myInstance.someMethod (some value); Then try to get the value in the array: var valueInArrayThatIWant = CFArrayGetValueAtIndex (cfArr, 0); However, I get the error unmanaged & lt; Cfarray & gt; Not like 'CFArray' . Unmanaged & lt; Cfarray & gt; also means? I looked, but I do not need to change the array in a fast array (though it would be good). I need to be able to get value from the array. I also tried CFArray method to pass in a function: func doSomeStuffOnArray (myArray: NSArray) {} Although I get the same error when using: doSomeStuffOnArray (cfArr); // unmanaged & lt; CFArray & gt; I am using CFArray because I want to sto...
