C++ The foreach Loop
The foreach Loop
There is also a "for-each loop" (also known as ranged-based for loop), which is used exclusively to loop through elements in an array (or other data structures):
Syntax
for (type variableName : arrayName) {
// code block to be executed
}
The following example outputs all elements in an array, using a "for-each loop":
Example
int myNumbers[5] = {10, 20, 30, 40, 50};
for (int i : myNumbers) {
cout << i << "\n";
}

Note: Don't worry if you don't understand the example above. You will learn more about arrays in the C++ Arrays chapter.
Good to know: The for-each loop was introduced in C++ version 11 (2011).
