The article deals with using dynamic arrays in the C language. The way to handle dynamically scalable values in C is to manipulate pointers in a continuous way. From the C point of view, an array is nothing more than a block of memory that can be addressed as a group of elements of ...
Using the header file definition, the following file is used to implement these methods. As discussed in the previous section ‘void pointers’ are used to reference the collection elements. Void pointers are pointers which point to some arbitrary data that has no specific type. As a consequence...

; } This compiles and runs successfully, but sizeof(tab_list) returns, not (max_elements * sizeof(tab_data_p))... That has me worried I'm not really allocating an array of pointers like I think I am... How can I ensure that I really allocated what I think I did??
In the thread I cited, Steve has a nice succinct reply (here), writing: "If you want "dynamic arrays", use ALLOCATABLE. If you want to be able to have pointers that can point to parts of other arrays, use POINTER." Translate 0 Kudos Copy link Reply jimdempseyatthecove Honored C...
C malloc() The name "malloc" stands for memory allocation. Themalloc()function reserves a block of memory of the specified number of bytes. And, it returns apointerofvoidwhich can be casted into pointers of any form. Syntax of malloc() ...
