C-無法將1個參數從int轉換為int [] [4]

Question

我的C編譯器發生錯誤，無法執行任何操作，我在網上沖浪尋求解決方案，但未能解決問題

第一個錯誤： error C2664: 'int get_min_distance(int *[][4],int,int,int,int)' : cannot convert argument 1 from 'int' to 'int *[][4]'

第二個錯誤： IntelliSense: argument of type "int" is incompatible with parameter of type "int (*)[4]"

兩個錯誤都在一行

碼：

#include<stdio.h>
#define inf  100000
int get_min_distance(int a[4][4], int b, int c, int d, int e);



int main(){
    int ras = 0;
    scanf("%d", &ras);

    int yal = 0;
    scanf("%d", &yal);

    int mabda = 0;
    scanf("%d", &mabda);

    int magsad = 0;
    scanf("%d", &magsad);


    int gf[4][4];
    gf[0][0] = 0;
    gf[0][1] = 1;
    gf[0][2] = inf;
    gf[0][3] = 1;
    gf[0][4] = 5;
    gf[1][0] = 9;
    gf[1][1] = 0;
    gf[1][2] = 3;
    gf[1][3] = 2;
    gf[1][4] = inf;
    gf[2][0] = inf;
    gf[2][1] = inf;
    gf[2][2] = 0;
    gf[2][3] = 4;
    gf[2][4] = inf;
    gf[3][0] = inf;
    gf[3][1] = inf;
    gf[3][2] = 2;
    gf[3][3] = 0;
    gf[3][4] = 3;
    gf[4][0] = 3;
    gf[4][1] = inf;
    gf[4][2] = inf;
    gf[4][3] = inf;
    gf[4][4] = 0;



    int distance = get_min_distance(gf [4][4], ras, yal, mabda, magsad);     //Error is here on "gf [4][4]"
    printf("%d", distance);


}


int get_min_distance(int gf[4][4], int ras, int yal, int mabda, int magsad){

    int min = inf;
    int i = ras;
    int A[5];

    if (mabda == magsad){
        return 0;
    }
    if (yal >= ras - 1){
        return inf;
    }
    for (int i = 0; i < ras; i++){
        if (gf[i][magsad] != 0 && gf[i][magsad] != inf){
            A[i] = gf[i][magsad] + get_min_distance(gf, ras, yal + 1, mabda, i);
            if (min>A[i] && A[i] > 0){
                min = A[i];
            }
        }
    }
    return min;
}

調用get_min_distance函數時發生錯誤知道嗎？ 謝謝

Answer 1

提供數組名稱作為參數

int distance = get_min_distance(gf, ras, yal, mabda, magsad);     
                               ^^^ 

同樣，該數組的初始化無效

int gf[4][4];
gf[0][0] = 0;
gf[0][1] = 1;
gf[0][2] = inf;
gf[0][3] = 1;
gf[0][4] = 5;
     ^^^
gf[1][0] = 9;
gf[1][1] = 0;
gf[1][2] = 3;
gf[1][3] = 2;
gf[1][4] = inf;
     ^^^
gf[2][0] = inf;
gf[2][1] = inf;
gf[2][2] = 0;
gf[2][3] = 4;
gf[2][4] = inf;
     ^^^
gf[3][0] = inf;
gf[3][1] = inf;
gf[3][2] = 2;
gf[3][3] = 0;
gf[3][4] = 3;
     ^^^
gf[4][0] = 3;
  ^^^
gf[4][1] = inf;
  ^^^
gf[4][2] = inf;
  ^^^
gf[4][3] = inf;
  ^^^
gf[4][4] = 0;
  ^^^^^^

因為索引的有效范圍是[0, 3]

Answer 2

gf[4][4]是gf數組的整數（超出范圍）

只需傳遞gf變量：

get_min_distance(gf, ras, yal, mabda, magsad)

注意：這是錯誤的，也是超出范圍的，您的數組過小。 [4][4]表示最大合法索引為3 ，否則您將覆蓋一些您不擁有的內存：

gf[4][0] = 3;
gf[4][1] = inf;
gf[4][2] = inf;
gf[4][3] = inf;
gf[4][4] = 0;

（您可能會在尺寸標注中指[5][5] ）
