How can we pass a whole structure to a function in C explain with example?
We can pass the C structures to functions in 3 ways:
- Passing each item of the structure as a function argument. It is similar to passing normal values as arguments.
- Pass the whole structure as a value.
- We can also Pass the address of the structure (pass by reference).
What is C programming structure?
A struct in the C programming language (and many derivatives) is a composite data type (or record) declaration that defines a physically grouped list of variables under one name in a block of memory, allowing the different variables to be accessed via a single pointer or by the struct declared name which returns the …

How do we declare a structure give an example?
struct sample /* Defines a structure named x */ { char c; float *pf; struct sample *next; } x; The first two members of the structure are a char variable and a pointer to a float value. The third member, next , is declared as a pointer to the structure type being defined ( sample ).
