Question
Ptr = (struct node *) malloc(x(struct node)); what is x in the above statement?Optionssizeoflengthoftypeofrangeof
Solution
The "x" in the above statement should be "sizeof". The "sizeof" operator in C is used to calculate the size of variables, constants, arrays, structures, etc. It is used here to determine the size of the structure 'node' so that the appropriate amount of memory can be allocated using malloc.
