Ptr = (struct node *) malloc(x(struct node));  what is x in the above statement?Optionssizeoftypeofrangeoflengthof

Break Down the Problem

1. In the expression malloc(x(struct node)), we need to determine what x represents in this context.
2. The expression is related to memory allocation, specifically for creating a structure of type struct node.

Relevant Concepts

1. Memory Allocation: The malloc function in C is used to allocate a specific amount of memory.
2. Type Size: The sizeof operator is commonly used to determine the size of a data type or structure.

Analysis and Detail

1. The correct syntax for allocating memory for a structure is generally malloc(sizeof(struct node)).
2. In the context of the options provided:
   • size of refers to the size of the structure (correct context).
   • type of is not directly related to memory allocation size.
   • range of does not apply here.
   • length of does not typically pertain to data structure sizes in C.

Verify and Summarize

• Given the necessity of specifying the size in the malloc function for proper memory allocation, option size of is confirmed as the correct answer.

Final Answer

The value of x in the statement Ptr = (struct node *) malloc(x(struct node)); is size of.
