Xcode 오류 : 아키텍처 x86_44에 대한 정의되지 않은 기호 및 아키텍처에 대한 기호가 없습니다. x86_64

Question

사용자가 2D 배열의 크기를 만든 다음 각 배열 공간을 채우기 위해 숫자를 입력 할 수있게하는 코드를 만듭니다. 그런 다음 학교 프로젝트의 Magic Square인지 확인해야하지만 위의 두 가지 오류가 계속 발생합니다. 여기

내 전체 코드입니다 :

#include <iostream> 

bool isMagicSquare(int row, int col, int magicSquare); 

using namespace std; 

int main() 
{ 
int row, col; 
int input = 0; 
cout << "Enter the number of rows: "; 
cin >> row; 
cout << endl; 
cout << "Enter the number of columns: "; 
cin >> col; 
cout << endl; 

int magicSquare[row][col]; 

if (col != row) 
{ 
    cout << "Sorry, this cannot be a magic square." << endl; 
    cout << "Enter the number of rows: "; 
    cin >> row; 
    cout << endl; 
    cout << "Enter the number of columns: "; 
    cin >> col; 
    cout << endl; 
} 
else if (col == row) 
{ 
    for (int i = 0; i < row; i++) 
    { 
     for (int j = 0; j < col; j++) 
     { 
      cout << "Enter a number for row " << i+1 << " column " << j+1 << ": "; 
      cin >> input; 
      magicSquare[i][j] = input; 
     } 
    } 

} 

isMagicSquare(row, col, magicSquare[row][col]); 
{ 
    if (isMagicSquare(row, col, magicSquare[row][col]) == true) 
    { 
     cout << "This is a magic square." << endl; 
    } 
    if (isMagicSquare(row, col, magicSquare[row][col]) == false) 
    { 
     cout << "This is not a magic square." << endl; 
    } 

} 

return 0; 
} 

bool isMagicSquare(int row, int col, int magicSquare[row][col]) 
{ 
int rowTotal, colTotal, diagA, diagB; 
rowTotal = 0; 
colTotal = 0; 
diagA = 0; 
diagB = 0; 

for (int r = 0; r < row; r++) 
{ 
    rowTotal = 0; 
    for (int c = 0; c < col; c++) 
    { 
     rowTotal += magicSquare[r][c]; 
    } 

} 
for (int c = 0; c < col; c++) 
{ 
    colTotal = 0; 
    for (int r = 0; r < row; r++) 
    { 
     colTotal += magicSquare[ r ][ c ]; 
    } 
} 
for (int r = 0; r < row; r++) 
{ 
    diagA += magicSquare[r][r]; 
} 
for (int i = 0; i < row; i++) 
{ 
    diagB += magicSquare[i][i]; 
} 
if (rowTotal != colTotal) 
{ 
    return false; 
} 
else if (diagA != rowTotal) 
{ 
    return false; 
} 
else if (diagB != rowTotal) 
{ 
    return false; 
} 

return true; 
} 

여기에 전체의 오류 메시지입니다 : 나는 시도하고 문제를 해결하기 위해 여러 가지를 시도했습니다

코드의 문제는 이 서명

bool isMagicSquare(int row, int col, int magicSquare); 

와 ismagicsquare 기능을 선언하지만 이 첫 번째 선언 나뭇잎 다른 서명

bool isMagicSquare(int row, int col, int[][] magicSquare); 

와에게 기능을 정의한다는 것입니다 정의가 없다. 또한

이 구현하는 간단한 방법은이 일을
