Как решить эти проблемы

---

#include<iostream>
#include<string>
#include<vector>
using namespace std;

const int CHARBOARDROWS = 7;
const int CHARBOARDCOLS = 5;

struct Input
{
    string userInput;
    int x;
    int y;
    int choice;
    int timeStep;
    int speed;
};

Input info;

void displayBoard();
Input inputProcess();
void displayA(vector<vector<char>> , int , int);

int main()
{
    vector<vector<char>> letterA;
    letterA.resize(CHARBOARDROWS, vector<char>(CHARBOARDCOLS));

    inputProcess();

    displayBoard();
    displayA(letterA,CHARBOARDROWS,CHARBOARDCOLS);

    return 0;
}

void displayBoard()
{
    int numOfRows = 20;
    int numOfCols = 40;
    if ((info.y)!>numOfRows || (info.x)!>numOfCols)
    {

        displayA(A,CHARBOARDROWS,CHARBOARDCOLS);
    }
    for (int row=0;row<numOfRows;row++)
    {
        for (int column=0;column<numOfCols;column++)
        {
                cout<<'*';
        }
        cout<<"\n";
    }
}

Input inputProcess()
{
    //Input info;

    cout<<"Please input a string (can up to 25 character long) :\n";
    getline(cin,info.userInput);
    cout<<"\n*********************************************";
    cout<<"\nAnchor dot is the top left dot of the string.";
    cout<<"\n*********************************************";
    cout<<"\n\nPlease input coordinate x of anchor dot : \n";
    cin>>info.x;
    cout<<"\nPlease input coordinate y of anchor dot :\n";
    cin>>info.y;
    cout<<"\nPlease choose to display the string :";
    cout<<"\n1-scrolling from left to right";
    cout<<"\n2-scrolling from right to left";
    cout<<"\n3-scrolling upwards";
    cout<<"\n4-scrolling downwards";
    cout<<"\n5-stationary without scrolling\n\n"<<"INPUT :";
    cin>>info.choice;
    cout<<"\n*********************************************";
    cout<<"\nOne time step is one refresh cycle which is\n"
        <<"made up of a screen clearing process and a\n"
        <<"display process.";
    cout<<"\n*********************************************";
    cout<<"\n\nPlease input number of time steps :\n";
    cin>>info.timeStep;
    cout<<"\nPlease input speed (between 1 to 10) :\n";
    cout<<"1-the slowest\t 10-the fastest\n";
    cin>>info.speed;
    displayBoard();
}

void displayA(vector<vector<char>> A, int row, int column)
{
    A[0][2] = '#';
    A[1][1] = '#';
    A[1][3] = '#';
    A[2][0] = '#';
    A[2][4] = '#';
    A[3][0] = '#';
    A[3][4] = '#';
    A[4][0] = '#';
    A[4][1] = '#';
    A[4][2] = '#';
    A[4][3] = '#';
    A[4][4] = '#';
    A[5][0] = '#';
    A[5][4] = '#';
    A[6][0] = '#';
    A[6][4] = '#';
    cout<<A[row][column];
}
}

Что я уже пробовал:

Ошибки находятся в очереди

if ((info.y)!>numOfRows || (info.x)!>numOfCols)

и линия

displayA(A,CHARBOARDROWS,CHARBOARDCOLS);

и он показывает, что не может распознать А. Почему это происходит и как исправить эти две ошибки?
