Dec 27, 2016 Write a C program to Count number of times a function is called. Here’s simple C program to Count the number of times a function is called by objects in C Programming Language. Here is an algorithm to get the leaf node count. GetLeafCount(node) 1) If node is NULL then return 0. 2) Else If left and right child nodes are NULL return 1. 3) Else recursively calculate leaf count of the tree using below formula. Leaf count of a tree = Leaf count of left subtree + Leaf count of right subtree.

Description
The C++ function std::algorithm::count() returns the number of occurrences of value in range. This function uses operator for comparison.
Declaration
Following is the declaration for std::algorithm::count() function form std::algorithm header.
C++98
Parameters
Auto-tune 7 vst v712.exe. first − Input iterators to the initial positions of the searched sequence.
last − Input iterators to the final positions of the searched sequence.
val − Value to search for in the range.
Return value
Returns the number of elements in the range of first to last.
Exceptions
Throws an exception if either element assignment or an operation on an iterator throws exception.
Please note that invalid parameters cause undefined behavior.
Time complexity
Linear in the distance between first to last.
Example
The following example shows the usage of std::algorithm::count() function.
Let us compile and run the above program, this will produce the following result −
