Arrays in C Programming: Operations on Arrays

What is an Array?

An array is a collection of elements of the same data type stored in contiguous memory locations.

Declaration and Initialization

int marks[5] = {90, 85, 78, 92, 88};
printf("%d", marks[0]);  // 90

Common Operations on Arrays

• Traversal — visiting each element, typically using a loop.
• Insertion — adding a new element at a given position.
• Deletion — removing an element and shifting the rest.
• Searching — linear or binary search to find an element.
• Sorting — arranging elements in ascending or descending order.

for (int i = 0; i < 5; i++) {
    printf("%d ", marks[i]);
}
