Check out example codes for "for loop c++". It will help you in understanding the concepts better.

Code Example 1

//'i' can be any number
//Can be any comparison operater 
//can be any number compared
//can be any mathmatic operater

for (int i = 0; i<100; i++){
//Do thing
}

Code Example 2

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

Code Example 3

#include <iostream>

using namespace std;

int main(){
 
  int i; //initialize integer
  //i starts at 0 and stops at 4, as 5 is not < 5
  for (i = 0; i < 5; i++){ //i++ means add 1 to i each iteration
    cout << "number " + i << endl; //print 5 times
  }
  return 0;
}
//output:
/*
number 0
number 1
number 2
number 3
number 4
*/

Code Example 4

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

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

Code Example 5

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

Code Example 6

//'i' can be any number
//Can be any comparison operater 
//can be any number compared
//can be any mathmatic operater

for (int i = 0; i<100; i++){
//Do thing
}
