sir, when we write node class for a hashtable during implementation we use node means we are giving a datatype T to the node but sir node is a pointer to the head of the linked list and how we met a requirement to specify a datatype of a node…
please sir explain me its getting a bit confusing for me…
Why adatatype is required for a node?
Hello @we_kaash
pointer will have some datatype right? like it might be pointed to char or int or another datatype here we need to mention the same type.
but sir when we implemented linked list and tree we did’nt specified any data type to the node
…
we havent made them generic , we always assumed that data will be int.
if we need to make them genric then in that case T placeholder and datatype is needed
so it means if we implement a class node and declare a pointer then by default it points to an integer till we specify its datatype?
…
no , we do mention the data while declaring the node
pls read about generic programming then only u will get some idea
