Solve the Tower of Hanoi problem.

Function Documentation

◆ main()

int main ( void )

Main function

           {
    struct tower F, U, T;
 
    F.top = 0;
    U.top = 0;
    T.top = 0;
 
    int no;
 
    std::cout << "\nEnter number of discs : ";
    std::cin >> no;
 
    for (int i = no; i > 0; i--) {
        F.values[F.top++] = i;
    }
 
    show(&F, &T, &U);
    TH(no, &F, &U, &T);
 
    return 0;
}

Here is the call graph for this function:

◆ mov()

void mov	(	tower *	From,
		tower *	To )

Move one disc from one tower to another

Parameters

[in,out]	From	tower to move disk from
[in,out]	To	tower to move disk to

                                 {
    --From->top;
    To->values[To->top] = From->values[From->top];
    ++To->top;
}

◆ show()

void show	(	const struct tower *const	F,
		const struct tower *const	T,
		const struct tower *const	U )

Display the towers

                                       {
    std::cout << "\n\n\tF : ";
    for (int i = 0; i < F->top; i++) {
        std::cout << F->values[i] << "\t";
    }
    std::cout << "\n\tU : ";
    for (int i = 0; i < U->top; i++) {
        std::cout << U->values[i] << "\t";
    }
    std::cout << "\n\tT : ";
    for (int i = 0; i < T->top; i++) {
        std::cout << T->values[i] << "\t";
    }
}

◆ TH()

void TH	(	int	n,
		tower *	From,
		tower *	Using,
		tower *	To )
