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

Code Example 1

// ------------------- Syntax of Loops ---------------------- //

// ----- FOR LOOP ----- //
// for (start value; condition; increment)

 for (int i = 0; i < 10; i++) {
  
    Console.WriteLine(i);
 }


// ----- WHILE LOOP ----- //
// start_value = 0; while (condition) { increment++ }

 int counter = 0;

 while (counter < 5) {
    
   Console.WriteLine(counter);
   counter++;
 }


// ----- DO WHILE LOOP ----- //
// start_value = 0; do { increment++ } while (condition);

 int counter = 0;

 do
 {
   Console.WriteLine(counter);
   counter++;
   
  } while (counter < 5);


// ----- FOREACH LOOP ----- //
// for (item in list/array)

 string[] myArray = { "grape", "orange", "pink", "blue" };

 foreach (string item in myArray) {
    
   Console.WriteLine(item);
 }

Code Example 2

/* 	for( declartion ; question ; operation )
	the semi-colon(;) is a must but the declation, question and opertion is not
 	the declation question and operation can be swaped to your liking 
	and even removed completly */
// examples: 
for(int i = 0; i < 3; i++)  // output:
{							//	Hi
  Console.WriteLine("Hi");	//	Hi
}							//	Hi
for(int i = 0; i < 3; i++)  // output:
{							//	0
  Console.WriteLine(i);		//	1
}							//	2
// pay attention to this question it's <= instead of <
for(int i = 5; i <= 8; i++)  // output:
{							//	5
  Console.WriteLine(i);		//	6
}							//	7
							// 	8
for(int i = 3; i > 0; i--)  // output:
{							//	3
  Console.WriteLine(i);		//	2
}							//	1
for(;;) // this will result in an infinite loop
{
 	// code here
}

Code Example 3

//You can use variables for this as well but im a stupid kid so no.
float kills = 10f
while(kills < 0)
{
  Debug.Log("Kids Rule bwahahahhaha")
}

Code Example 4

for (int i = 0; i < 10; i++)
{
    Console.WriteLine("Value of i: {0}", i);
}
