正在获取另一个函数作用域中的参数值

我不知道如何将读取输入的变量放入计算席位的范围。不管我如何声明变量，而不是重新定义它们；函数calculateSeats似乎找不到行、列和数组seatingChart。

*添加了calculateSeats（seatingChart[行][列]）*

int main() {
    int seatsSold = 0, oneSeat = 0, seatsTogether = 0, threeSeats = 0, fourSeats = 0, fiveSeats = 0, noSeats = 0, totalSold = 0, 
    rows, columns, pecentageSold, i;
    const int SIZE = 50;
    char seatingChart[SIZE][SIZE];
    readInput(rows, columns, seatingChart[rows][columns]); // Call read input.
    // Values of read input are then passed to calculate values. 
    calculateSeats(seatsSold, oneSeat, seatsTogether, threeSeats, fourSeats, fiveSeats, noSeats, i);
    // Calculated valus are then declared as calculated values and passed to write output. 
    /* int calculatedValues = calculateSeats(seatsSold, oneSeat = 0, seatsTogether = 0, threeSeats = 0, 
                                          fourSeats = 0, fiveSeats = 0, noSeats = 0); */
    // Function is called to write the output.
    writeOutput(seatsSold, oneSeat, seatsTogether, threeSeats, fourSeats, fiveSeats, noSeats, pecentageSold, totalSold); 
    return 0; // Program ends.
}
// Function is needed for assigning values to the char array. Values are then passed from read to calculate. 
int readInput(int & rows, int & columns, int i) {
    const int SIZE = 50;
    int seatingChart[SIZE][SIZE];
    ifstream inputFile;
    inputFile.open("SeatingChart.txt");
    for (rows; rows < SIZE; rows++) { // Step through the valueless array and give the array values.
        for (columns; columns < SIZE; columns++)
            inputFile >> seatingChart[rows][columns]; // Assign the array values from the input file. 
    }
    inputFile.close();
    calculateSeats(seatingChart[rows][columns]);
    return 0;
}

                seatsTogether++;
                    if (seatsTogether > 1) {
                        threeSeats++;
                    if (seatsTogether > 2) {
                        fourSeats++;
                    }
                    if (seatsTogether > 3) {
