Static Memory Allocation in C | Data Segment Explained with Examples

## Memory allocation in C : Part 2 ##
📌 Static Memory Allocation in C
Static memory allocation is one of the most fundamental concepts in C programming. In this approach, memory size is decided at compile time, and the allocated memory remains fixed throughout the program’s execution.
🔹 Key characteristics of static memory allocation:
Memory is allocated before program execution
Size cannot be changed at runtime
Memory is managed automatically by the compiler
Faster access compared to dynamic allocation
No risk of memory leaks
🔍 Common examples include:
Global variables
Static variables
Fixed-size arrays

int a = 10;
static int count;
int arr[10];
💡 Where static allocation is useful:
Embedded systems with limited memory
Real-time applications
Programs where memory requirements are known in advance
Situations where reliability is more important than flexibility
⚠️ Limitations:
Memory cannot be resized
Can lead to wasted memory if not planned carefully
Less flexible than dynamic allocation
Understanding static memory allocation helps build a strong foundation for mastering stack and heap memory, and is essential before moving on to dynamic memory concepts.
