What is static memory allocation in C Language?

In case of static memory allocation, memory is allocated at compile time, and memory can’t be increased while executing the program. It is used in the array.
The lifetime of a variable in static memory is the lifetime of a program.
The static memory is allocated using static keyword.
The static memory is implemented using stacks or heap.
The pointer is required to access the variable present in the static memory.
The static memory is faster than dynamic memory.
In static memory, more memory space is required to store the variable.

For example:
int a[10];

The above example creates an array of integer type, and the size of an array is fixed, i.e., 10.
