Passing Structures to Functions

When a structure is used as an argument to a function, the entire structure is passed by using the standard call-by-value parameter passing mechanism. This, of course, means that any changes made to the contents of the structure inside the function to which it is passed do not affect the structure used as an argument. However, be aware that passing large structures can incur significant overhead. (As a general rule, the more data passed to a function, the longer it takes.)

When using a structure as a parameter, remember that the type of the argument must match the type of the parameter. For example, the following program declares a structure called sample, and then a function called f1( ) that takes a parameter of type sample.


// Pass a structure to a function.
#include <iostream>
using namespace std;
// define a structure type
struct sample {
int a;
char ch;
} ;
void f1(sample parm);
int main()
struct sample arg; // declare arg
arg.a = 1000;
arg.ch = 'X';
return 0;
void f1(sample parm)
cout << parm.a << " " << parm.ch << "\n";

Here, both arg in main( ) and parm in f1( ) are of the same type. Thus, arg can be passed to f1( ). If the structure types had differed, a compile-time error would have resulted.
