for loops in c++

I am writing a program using for loops and outputting the number of iterations in each loop. However, my program is outputting a line for every iteration of the loop, not just the total number of iterations.

Is there a way to count the number of iterations of a loop and output that total?

Attached is the program.

Code:

---

int Counter = 0;

for(int i=0; i<10; i++)
{
  Counter++;

  ... //Do whatever you want
}

cout << Counter;

---

You could also print i+1, but that depends on which starting value i has. A general formula for this loop:

for(int i=a; i<b; i++)

would be: b-a times (assuming that the for loop completes, and is not breaked).

You mean something like:

Code:

---

int cnt = 0;
for (int i = -10; i <= 10; i++)
{
  cnt++;
}

cout << "Loop 4 executes " << cnt << " times.";

---

}

Thanks for your help.

In my program I am running 7 for loops, using counter for each one leaves me with each loop adding its iterations to the counter. Do I need to use a different name for each counter?

Depends. If you print the result after each loop you can use the same. Just remember to nullify it (set it to 0) after every loop.

Code:

---

int Counter = 0;

for(...)
{
  Counter++;
}

cout << "Loop 1: " << Counter;
Counter = 0;

for(...)
{
  Counter++;
}

cout << "Loop 2: " << Counter;
Counter = 0;

for(...)
{
  Counter++;
}

cout << "Loop 3: " << Counter;

edit: I guess I answered his question about the same time Magos did... sorry;)

Thanks for your help again. I am just getting started so I'm sure most of my questions will be easily answered.
