Hi shadowplayer28,
I do not know why you gave the title like that. But this program can be fixed I think. I see you can the function transaction(), but I cannot see it in the decleration part, like this,

public:
void transaction();

And where the functin is implemented.
Correct:

public:
...
void transaction();
...

void Bank::transaction()
{;}

I already tested the program, that's fine. I used g++ as the compiler (g++ -o main.exe main.cpp).
Hope it helps!

Edward_3: I think you missed the point. The OP needs a C program, and cannot use the C++ version, for whatever reason s/he has.

shadowplayer28: Just what are you trying to accomplish by re-writing the program in C? Why do you need it to be in C, and not in C++? Is this your original code, or something you found on the net, and if the latter, are you certain it is really what you need? Do you know both languages, and do you understand the ways they differ and why?
