Match the following (List- I) with their functions (List- II). List-I List-II (I) static char var; (A) Sequence of memory locations to store addresses (II) m = malloc(10); m = NULL; (B) A variable located in data section of memory (III) char * ptr [10] (C) Request to allocate a CPU register to store data (IV) register int var1; (D) A lost memory which cannot be freed

(I)-(B), (II)-(D), (III)-(A), (IV)-(C) Explanation: Let us map each item from List-I to its precise definition in List-II: : static char var; Variables declared with the static storage class have a lifetime throughout the execution of the program. In the memory layout of a program, initialized static variables reside in the Data Segment , while uninitialized ones reside in the BSS segment (both are parts of the broader data section of memory). : m = malloc(10); m = NULL; malloc(10) dynamically allocates of memory on the heap and returns its address to pointer m . Setting m = NULL without freeing the allocated block means the program loses the address reference to that block. This results in a Memory Leak (a lost piece of memory that can no longer be accessed or freed by the program). : char * ptr [10] This statement declares an array of poi

Match the following (List- I) with their functions (List- II).

List-I	List-II
(I) `static char var;`	(A) Sequence of memory locations to store addresses
(II) `m = malloc(10); m = NULL;`	(B) A variable located in data section of memory
(III) `char * ptr [10]`	(C) Request to allocate a CPU register to store data
(IV) `register int var1;`	(D) A lost memory which cannot be freed

List-I Item	Technical Concept	Correct List-II Match
(I) `static char var;`	Static storage duration	(B) Data section variable
