Can you please give me a sample program about Turbo C with the topic of "pass by value and pass by reference".

thank you. God Bless

Can you please give me a sample program about Turbo C with the topic of "pass by value and pass by reference".
Function pass by value


void f(int n)


{


n = 0; // This changes n to zero


}





int main(void)


{


int i = 5;


printf("Before fn, i = %d\n", i);


f(i); // Pass a copy of i to function f(), f() will not change i.


printf("After fn, i = %d\n", i);


f(10); // This call is valid due to the fact that a copy of the value is passed to f().


}





By reference using pointers.


void f(int *n)


{


*n = 0; // This changes n to zero


}





int main(void)


{


int i = 5;


printf("Before fn, i = %d\n", i);


f(%26amp;i); // Pass a reference of i to function f(), f() will change i.


printf("After fn, i = %d\n", i);


// f(1); is invalid, require a variable for reference to work.


}





In C++, simplier function call by reference.


void f(int %26amp;n)


{


n = 0; // This changes n to zero


}





Call fn() with variables only.


int main(void)


{


int i = 5;


printf("Before fn, i = %d\n", i);


f(i); // Pass a reference of i to function f(), f() will change i.


printf("After fn, i = %d\n", i);


// f(1) will not work, require a variable as argument.


}
