If we are looking for a way to get the size of a data type in C#, mastering the sizeof() operator is just what we need. This operator returns the accurate memory size that any data type occupies. In this article, we will dive into understanding how to use this operator and apply it...
The above statement allocates 400 bytes of memory. It's because the size offloatis 4 bytes. And, the pointerptrholds the address of the first byte in the allocated memory. The expression results in aNULLpointer if the memory cannot be allocated. C calloc() The name "calloc" stands for ...

localIp.sin_addr.S_un.S_addr = INADDR_ANY; nErr = bind(myListener,(SOCKADDR *)&localIp,sizeof(localIp)); assert(nErr!=SOCKET_ERROR); nErr = listen(myListener, 5); assert(nErr==0); //Create a manual-reset event object.
user=malloc(sizeof(user_t)); user->id =233; user->cookie =244; HASH_ADD(hh, users, id,sizeof(int), user);return0; } Seemingly in HASH_ADD() function we use an undeclare variable “id”. But uthash is designed with C macros so it is all right and it is the rule we need ...

Variable length arrays were introduced in C99 version of C. Previously, techniques using the realloc function were used to support arrays whose sizes change. We illustrate the realloc function in the section Using the realloc Function to Resize an Array. Note Arrays have a fixed size. When we ...
