the goal of this code is to create a matrix of userNum x use

the goal of this code is to create a matrix of userNum x userNum size of distict random integers.

How can the printing for loop and vector creating for loop be rewritten into separate functions?

do

   {

do

{

   cout << \"\ Enter the size of the matrix: \";

   cin >> userNum;

   if (userNum < 2 && !isdigit(userNum))

cout << \"\ Error *** Must be an integer greater than 2\" << endl;

} while(userNum < 2);

vector<vector<int> > randMatrix;

cout << \"\ \ The perfect matrix that is created for size \" << userNum << \":\" << $

srand(time(NULL));

for (int i = 0; i < userNum; i++){

   vector<int> row;

   for(int j = 0; j < userNum; j++){

while ((rand() % 10) != row[i]){

   row.push_back(rand() % 10);

}

   }

   randMatrix.push_back(row);

}

for(int i = 0; i < randMatrix.size(); i++){

   for(int j = 0; j < randMatrix[i].size(); j++){

cout << randMatrix[i][j] << \" \";

   }

   cout << endl;

}

Solution

Below code is modified according to the seperate functions for creating and printing the matrix :

do
{
do
{
cout << \"\ Enter the size of the matrix: \";
cin >> userNum;

if (userNum < 2 && !isdigit(userNum))
cout << \"\ Error *** Must be an integer greater than 2\" << endl;
} while(userNum < 2);

vector<vector<int> > randMatrix;

cout << \"\ \ The perfect matrix that is created for size \" << userNum << \":\" << $

createVector(&randMatrix,userNum);


printMatrix(&randMatrix);
  
   }
  
   // Seperate methods for creating and printing matrix
  
   int createVector(vector<vector<int> > *randMatrix, int userNum){
   srand(time(NULL));
for (int i = 0; i < userNum; i++){
vector<int> row;
for(int j = 0; j < userNum; j++){
while ((rand() % 10) != row[i]){
row.push_back(rand() % 10);
}
}
randMatrix.push_back(row);
}
  
   }
  
   int printMatrix(vector<vector<int> > *randMatrix){
   for(int i = 0; i < randMatrix.size(); i++){
for(int j = 0; j < randMatrix[i].size(); j++){
cout << randMatrix[i][j] << \" \";
}
cout << endl;
  
   }
