Can you give an example of pass by value and reference on turbo c?

pass by value is when only the value of a variable gets changed within a function and is passed to a function like





func(a)





as oppsoed to pass by reference which will chang the data held at the memory register.





func(*a) would pass a pointer to the variable a, and therfore you could modify the contents of that memory

Turbo C? Wow, that certainly brought back my memory...





C language always pass by value.





int func(int a, int b) { .... }





When called by func(x,y), the values of x and y are copied to a and b, respectively.





To do call by reference in C, you do





int func(int* a, int* b) { ... }





When you call this by doing func(%26amp;x, %26amp;y), you copies the ADDRESS of variable x and y to a and b. When you do:





*a=100;





You assign 100 to the address of x.
