我试图在c ++中迭代网格并将每个坐标标记为false。我以为我做的是创建一个25x25的网格,但VC ++给了我两个错误:
(37)"error C2064: term does not evaluate to a function taking 0 arguments"
(44)"error C2448: 'markAllIncluded' : function-style initializer appears to be a function definition"
我正在使用stanford c ++ lib来处理我的一些头文件。
这是我的代码:
#include <iostream>
#include "console.h"
#include "maze.h"
#include "gwindow.h"
#include "grid.h"
#include "queue.h"
#include "random.h"
#include "simpio.h"
#include "stack.h"
#include "vector.h"
#include <array>
using namespace std;
//prototypes
const int numCols = 25;
const int numRows = 25;
Vector<int> rand_coords();
Grid<bool> markAllIncluded(numCols, numRows);
int main() {
Vector <int> coords = rand_coords(); //get random coords
cout << "(" << coords[0] << ", " << coords[1] << ")" << endl;
Grid<bool> included = markAllIncluded();
string x = included.toString();
cout << x;
return 0;
}
Grid<bool> markAllIncluded() {
Grid<bool> m(numRows, numCols);
for (int i=0; i <= numRows; i++) {
for (int j = 0; j <= numCols; j++) {
m.set(i, j, false);
}
}
return m;
}
Vector<int> rand_coords () {
Vector<int> coords(2);
coords[0] = randomInteger(0, numCols);
coords[1] = randomInteger(0, numRows);
//cout << "(" << coords[0] << ", " << coords[1] << ")" << endl;
return coords;
}
我的语法错了吗?当我将包含设置为markAllIncluded()l
时,我在main()中得到了错误答案 0 :(得分:1)
是的,你的语法错了。功能声明
Grid<bool> markAllIncluded(numCols, numRows);
不正确。你应该使用
Grid<bool> markAllIncluded();
(由于numRows
和numCols
是全球const
s),或
Grid<bool> markAllIncluded(int numCols, int numRows);
后面的定义也是如此。
答案 1 :(得分:0)
在声明函数时将标识符放在标识符之前
Grid<bool> markAllIncluded(int numCols, int numRows)
