如何计算一个循环执行了多少次？

Question

I am writing a program that prints products of a number, (for example, 2 can be 1 * 4, 2 * 2, 4 * 1 and counter shows (3) numbers), I need to have a counter that counts how many numbers were printed. I can't use (i) as a counter as it counts everything.

for(i=1; i<=number; i++)
{
    if(number%i==0)
    cout<<i<<"*"<<number/i<<"="<<number<<endl;
}
return 0;

Answer 1

Just add another variable and expand the body of the if-statement right?

int count = 0;
for(i=1; i<=number; i++)
{
  if(number%i==0) {
    cout<<i<<"*"<<number/i<<"="<<number<<endl;
    count++;
  }
}
cout << "Printed " << count << " times" << endl;
return 0;

Answer 2

Because i is declared outside of the loop, gets initialized to 1, and is already incremented by 1 each iteration, you can just print it out after.

int i;
for(i=1; i<=number; i++)
{
    if(number%i==0)
    cout<<i<<"*"<<number/i<<"="<<number<<endl;
}
cout << "Looped " << i << " times\n";
return 0;

Just note i must be declared outside the loop.
