Access Elements in C++ Array
To access elements in a C++ array, follow these steps:
- Declare the Array: Create an array and initialize it with elements.
cpp
int myArray[5] = {10, 20, 30, 40, 50};
- Access an Element by Index: Use the index of the element within square brackets to access the value at that index.
cpp
int thirdElement = myArray[2]; // Accessing the third element (index 2)
- Modify an Element: Use the index to modify the value of an element in the array.
cpp
myArray[1] = 100; // Modifying the value of the second element (index 1)
- Iterate Through the Array: Use a loop to iterate through the array and access each element.
cpp
for (int i = 0; i < 5; i++) {
cout << myArray[i] << " "; // Output each element separated by a space
}
- Use Pointer Arithmetic: You can also use pointer arithmetic to access array elements.
cpp
int fifthElement = *(myArray + 4); // Accessing the fifth element using pointer arithmetic
These steps will allow you to effectively access and manipulate elements within a C++ array.
