Question

I wanted to start programming and know how it works in both pseudocode and c#

String carName;

                    String carPlate;

                    int i, j;

                    for (i = 0;i < size of carPark; i = i+1

                    for int b = 0;i < 2; b = b+1

                        carPark[i][b] = "empty";

                    // When guest comes

                    carName = Userinputs name;

                    carPlate = User inputs plate;

                    for int i = 0, i< size of carPark; i = i+1

                    for int b = 0; b<2; b= b+1

                        if carPark[i][b] ==/equals to "empty"

                    carPark[i][b] = carName;

                    carPlate[i][b+1] = carPlate;

                    return "Car has bee placed at space " + i

                    return "No empty spaces left"

                        // When guest leaves

                    for int i = 0, i< size of carPark; i = i+1

                    for int b = 0; b<2; b= b+1

                        if carPark[i][b] ==/equals to carName

                            carPark[i][b] = "empty"

                    carPark[i][b+1] = "empty"

                    return "Car has bee placed at space " + i

                    return "Car not found"
