how to make a for loop in c++ code example

Example 1: c++ for loop

//'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
}

//more info on operaters

Example 2: for loop c++

#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
*/

Example 3: for loop in cpp

//limit can be any number
//you can use any comparison operator

for(int iteration = 0; iteration < limit_number; iteration++)
{
	//action in for loop
}
