C++ Arrays and Loops
Loop Through an Array
You can loop through the array elements with the for
loop.
The following example outputs all elements in the cars array:
Example
string cars[4] = {"Volvo", "BMW", "Ford", "Mazda"};
for(int i = 0; i < 4;
i++) {
cout << cars[i] << "\n";
}
Run example »
The following example outputs the index of each element together with its value:
Example
string cars[4] = {"Volvo", "BMW", "Ford", "Mazda"};
for(int i = 0; i < 4;
i++) {
cout << i << ": " << cars[i] << "\n";
}
Run example »
The example above can be read like this: for each
string element (called
i - as in
index) in cars, print out the value of i.
If you compare the for loop and for-each loop, you will see that the for-each method is easier to write, it
does not require a counter, and it is more readable.
