Range Based For Loop in C++

C++ foreach

We need to put what data type is
Create a temporary variable to store each element
array name, data name
Syntax is much nicer
In Other Programming languages, It Something ForEach Loop

for(int n:data){} like that

foreach c++

			
					#include <iostream>
#include <array>

int main() {
  int data[] = {
    10,
    11,
    12,
    13,
    14,
    15,
    16
  };
  for (int n: data) {
    std::cout << n << "t";
  }
  std::cout << "n";
}

It returns

			
					10   11   12   13   14   15   16

You Can do it with Vector as well.

			
					#include <iostream>
#include <vector>
#include <array>

int main() {
  std::vector <int> data = {
    10,
    11,
    12,
    13,
    14,
    15,
    16
  };
  for (int n: data) {
    std::cout << n << "t";
  }
  std::cout << "n";
}

It returns the Same as well.

			
					10   11   12   13   14   15   16

Its Eliminates errors, much easier to read. It's Much Handier When we need to iterate through every element in an array. It is a Pretty Simple Concept
