Foreach in C++ and C#
Foreach in C++
C++ 11 introduced foreach loop to traverse over each element. Here is an example −
Example
#include <iostream>
using namespace std;
int main() {
int myArr[] = { 99, 15, 67 };
// foreach loop
for (int ele : myArr)
cout << ele << endl;
}Output
99 15 67
Foreach in C#
Let us see an example of foreach in C#. It traverses items in a collection −
Example
using System;
namespace ArrayApplication {
class MyArray {
static void Main(string[] args) {
int [] n = new int[10]; /* n is an array of 10 integers */
for ( int i = 0; i < 10; i++ ) {
n[i] = i + 100;
}
/* output each array element's value */
foreach (int j in n ) {
int i = j-100;
Console.WriteLine("Element[{0}] = {1}", i, j);
}
Console.ReadKey();
}
}
}Output
Element[0] = 100 Element[1] = 101 Element[2] = 102 Element[3] = 103 Element[4] = 104 Element[5] = 105 Element[6] = 106 Element[7] = 107 Element[8] = 108 Element[9] = 109
