Using Arrays with Loops in C++
Loops are commonly used to access and manipulate array elements efficiently. The for
loop is particularly useful for iterating over arrays.
Example: Printing Array Elements
#include <iostream>
int main() {
int numbers[] = {10, 20, 30, 40, 50};
int arraySize = sizeof(numbers) / sizeof(numbers[0]);
for (int i = 0; i < arraySize; i++) {
std::cout << "Element " << i << ": " << numbers[i] << std::endl;
}
return 0;
}
Key Takeaways
- Loops allow for efficient traversal of arrays.
- Use
sizeof()
to determine array size when necessary. - Ensure the loop index stays within array bounds to prevent errors.
