我的編譯器告訴我,我有一個錯誤,但我已經通過電子郵件發送了我的教師,他說我的代碼非常好。錯誤C2440,Battleship C++
的錯誤是錯誤:
1 error C4716: 'ShipPlacement' : must return a value, line 139
我不確定到哪裏出了錯正是因此我想分享我的代碼爲ShipPlacement
:
ShipPlacement(Coord grid[10][10])
{
CoordAndBearing SetBowAndDirection();
CoordAndBearing cab;
cab = SetBowAndDirection();
int start;
if((cab.dir == 3) || (cab.dir == 1)) // GOING HORIZONTAL //
{
if (cab.dir == 3)
start = cab.bx;
else
start = cab.bx - 4;
for(int i = start; i <= start + 4; i = i + 1)
{
grid[i][cab.by].isShip = true;
}
}
else // GOING VERTICAL
{
if(cab.dir == 0)
start = cab.by;
else
start = cab.by - 4;
for (int i = start; i <=start + 4; i = i + 1)
{
grid[cab.bx][i].isShip = true;
}
}
}
,這裏是我的int main
:
int main()
{
srand((unsigned int) time (NULL));
void ShipPlacement(Coord grid[10][10]);
Coord grid[10][10];
SetGridParameters(grid);
ShipPlacement(grid);
int ammo = 18;
int hits = 0;
while (hits < 5 && ammo >0)
{
int x;
int y;
DisplayGrid(grid);
cout << "Ammo left = " << ammo << endl;
cout << "Enter Coord: " << endl;
cin >> x >> y;
ammo= ammo - 1;
if (grid [x][y].isShip == true)
{
hits = hits + 1;
}
else
{
cout << " You missed... " << endl;
}
}
DisplayGrid(grid);
if(hits == 5)
{
cout << "You sunk the U.S.S McCall!!";
}
else
{
cout << " You lost ";
}
system("pause");
return 0;
}
您錯過了爲您的'ShipPlacement()'函數指定'void'返回類型。在這種情況下,一些編譯器會假設爲「int」,因此會引起投訴。 –
這些日子誰指導老師? –
