The function receives three Strings in the form of character pointers as the following: void findAndRepalce (char *text, char * oldval, char * newval) Your function should replace all occurrences of the string oldval by the newval. Assume that oldval by the newval have the same length. For example, given the following code: findAndRepalce("BACAACE EAA ZZADA","AC","PQ"); It should store the value "BPQAPQE EAA ZZADA" inside text. Print the three strings O o o

Below are thefunctionalities explained that are to be implemented:Check Record: It is a utility function of creating a record it checks before insertionthat the Record Already Exist or not. It uses the concept of checking for a Node with givenData in a linked list.Create Record: It is as simple as creating a new node in the Empty Linked list orinserting a new node in a non-Empty linked…This refers to data structures that have keys and values. A Dictionary B) Matrix (C) Lists D) TuplesLanguage/Type: C++ binary trees pointers recursion Write a function named hasPath that interacts with a tree of BinaryTreeNode structures representing an unordered binary tree. The function accepts three parameters: a pointer to the root of the tree, and two integers start and end, and returns true if a path can be found in the tree from start down to end. In other words, both start and end must be element data values that are found in the tree, and end must be below start, in one of start's subtrees; otherwise the function returns false. If start and end are the same, you are simply checking whether a single node exists in the tree with that data value. If the tree is empty, your function should return false. For example, suppose a BinaryTreeNode pointer named tree points to the root of a tree storing the following elements. The table below shows the results of several various calls to your function: 67 88 52 1 21 16 99 45 Call Result Reason hasPath(tree, 67, 99) true path exists…
