Which is better as far as functionality?

Question

for (rows = 0; rows < 6; rows++) {

for (cols = 0; cols < 6; cols++) {

if (matrix[rows][cols] == 0) {
matrix[rows][cols] = 1;
}
cout << matrix[rows][cols];
}

or

for (rows=0; rows < 6; rows++){

for (cols=0; cols < 6; cols++){

cout << matrix[rows][cols] + 1;
}
cout << endl;
}

In second case suppose you have matrix value 1 so it would be added in 1 and result would be 2

But in 1st case if matrix value is 1 then output would be 1.

So you cannot say both outputs are same.

If you want to make all elements 1 then just simply do this no need to check anything.

for (rows = 0; rows < 6; rows++) {

for (cols = 0; cols < 6; cols++) {

matrix[rows][cols] = 1;

cout << matrix[rows][cols];
}
}

Lexx Welcome my friend.

Answer 4

interestingly enough that was my first solution but I put the

matrix[rows][cols] = 1;

before the for statements so that was likely my issue in the first place. Thanks for the reply and help AJ.

Answer 5

Lexx

Do you want to add 1 or assign 1 to matrix?

Answer 6

it outputs the same so you are going to have to explain the diffrence.

Answer 7

all matrix elements are 0 I should have clarified that and the objective was to make all elements = 1.
