How many for loops are running in a program
The number of objects in a program
The names of the variables used in a program
How many times the for loop has iterated

Answer 1

i really need help

Answer 2

In a for loop of the format:

for(k=0;k>5;k++) {
//Code;
}

You use the iterator variable k to find out how many times the loop will run. You can count this by increasing k by 1 (k++) each time the loop runs until it reaches a value less than 5.

Answer 3

Yes that is the correct idea so the last answer 'How many times the for loop has iterated' is the correct response however in the above code the loop will never execute because k is never greater than 5. I suspect this is just a typo and if '>' was changes to '<' then it would indeed run 5 loops when k was equal to 0,1,2,3 and 4.
