Answer :
In the given code, we are executing a nested for-loop with variables x, row and col as integers. After execution of this code we can find that x is printed twice.
Therefore, the answer is option (c) 2.
Here we are executing a for loop. In the first iteration, when row = 0, 'x' is printed as row < 2.
Now in the nested for loop, there is nothing to execute and it exit the loop when col = 3.
Now row is incremented and new value of row = 1, and row < 2. So statement inside the loop is executing printing 'x' for the second time and then empty nested loop with variable col gets executed.
Again row gets incremented to row = 2, but row not less than 2, so we exit from the for loop. Therefore in total x is printed twice.
-- The question is incomplete, the complete question is as follows--
"How many letter x's will be output? Assume variables x, row, and col are integers. a. 6 b. 1 c. 2 d. 3
for(row = 0; row < 2; ++row){
System.out.print("x");
for(col = 0; col < 3; ++col){
// Do something
}}"
