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
