我的编译器告诉我我有错误,但我已通过电子邮件发送给我的导师,他说我的代码完全正常。
错误是错误:
1错误C4716:'ShipPlacement':必须返回第139行的值
我不确定到底哪里出错,所以我要分享ShipPlacement
的代码:
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;
}
}
}
这是我的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;
}
答案 0 :(得分:2)
您已定义ShipPlacement
函数而没有返回类型。一些(大多数?)编译器会发出警告,说明他们假设它返回int
,然后是错误,因为它没有。
只需将其明确定义为&#34;返回&#34; void
(即void ShipPlacement(Coord grid[10][10])
),你应该没事。
