how do for loops on c++

for(int i=0; i<=limit; i++)
{
	//statement
}

  for (int i = 0; i < 5; i++) {
  cout << i << "\n";
}

  

#include <iostream>
#define FOR(i,a) for (int i = 0; i < a; i++)

FOR(i, 3) cout << i << endl;

for (int i; i < 10; i++)
{
  cout << i << "\n";
}

for ( init; condition; increment ) {
   statement(s);
}
