Assigning Values To An Array

In order to accept arrays as parameters the only thing that we have to do when declaring the function is to specify in its parameters the element type of the array, an identifier and a pair of void brackets loop that prints out the array to know the range to iterate in the passed array without going out of range.

In both cases, local and global, when we declare an array, we have the possibility to assign initial values to each one of its elements by enclosing the values in braces would be 5 ints long, since we have provided 5 initialization values.In C it is syntactically correct to exceed the valid range of indices for an array.This can create problems, since accessing out-of-range elements do not cause compilation errors but can cause runtime errors.Arrays, both simple or multidimensional, passed as function parameters are a quite common source of errors for novice programmers.I recommend the reading of the chapter about Pointers for a better understanding on how arrays operate.Multidimensional arrays are just an abstraction for programmers, since we can obtain the same results with a simple array just by putting a factor between its indices: With the only difference that with multidimensional arrays the compiler remembers the depth of each imaginary dimension for us.Take as example these two pieces of code, with both exactly the same result.Without any other information, Swift creates an array that includes the specified values, automatically inferring the array’s You can access individual array elements through a subscript.The first element of a nonempty array is always at index zero.In C it is not possible to pass a complete block of memory by value as a parameter to a function, but we are allowed to pass its address.In practice this has almost the same effect and it is a much faster and more efficient operation.
