Passing Arrays and/or Array Elements. When one element of an array is passed to a function, it is passed in the same manner as the type of data contained in the array. ( I.e. pass-by-value for basic types. ) However when the entire array is passed, it is effectively passed by reference. These functions allow crossing the data in a number of ways and avoid explicit use of loop constructs. They act on an input list, matrix or array and apply a named function with one or several optional arguments. The called function could be: An aggregating function, like for example the mean, or the sum (that return a number or scalar);

a function (or name of a function) to be applied, or NULL. In the case of functions like + , %*% , etc., the function name must be backquoted or quoted. If FUN is NULL , tapply returns a vector which can be used to subscript the multi-way array tapply normally produces.

Access Elements in C++ Array. In C++, each element in an array is associated with a number. The number is known as an array index. We can access elements of an array by using those indices. // syntax to access array elements array[index]; Consider the array x we have seen above. Elements of an array in C++ Few Things to Remember: a. Use the array_values function to remove all gaps and re-index the array. b. Use a foreach loop to process the array, which skips elements that contain nulls. c. Use a for loop that contains extra code that skips elements that contain nulls. d. Use the array_fill function to replace all gaps in the array with empty strings. Matrix representation is a method used by a computer language to store matrices of more than one dimension in memory.

Hint: In C, C++, and Java, probably the best solution is to create a recursive helper function printPathsRecur(node, int path[], int pathLen), where the path array communicates the sequence of nodes that led up to the current call. Alternately, the problem may be solved bottom-up, with each node returning its list of paths.
