C++ Find

C++ Find

This is the function in C++ that is basically used to find the element that are in the given range of numbers. C++ find also used to return an iterator to the first element in the range [first,last] that basically compares the equal to val. In case there is no such element is found then the function returns the last.

C++ search generally returns an iterator back to the first element in the range [first,last] that basically compares equal to val. Last is returned by the function in case there is no such element is found.

The CPP find function basically uses the operator== in order to compare the individual elements to val.

Here is an example that will explain about the C++ find and the working of it, most important of all, it will let you understand the application aspect of it:

#include<bits/stdc++.h> 
int main () 
{ 
	std::vector<int> vect { 10, 11, 12, 13 }; 
	
	//store the position using iterator of searches element 
	std::vector<int>::iterator it; 
	
	// Original Vector print 
	std::cout << "Original vector :"; 
	for (int i=0; i<vect.size(); i++) 
		std::cout << " " << vect[i]; 
		
	std::cout << "\n"; 
	
	//Need  to searche element 12 
	int search = 12; 
	
	it = std::find (vect.begin(), vect.end(), search); 
	if (it != vect.end()) 
	{ 
	std::cout << "Element " << search <<" found at position : " ; 
	std:: cout << it - vect.begin() + 1 << "\n" ; 
	} 
	else
	{
		std::cout << "Element not found.\n\n"; 
	}	
	return 0; 
}
