C# loop code example

Example 1: for loop c#

/* 	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
}

Example 2: c# loop

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

Example 3: c# for loop example

for (int i = 0; i < 2; i++)
{
    for(int j =i; j < 4; j++)
        Console.WriteLine("Value of i: {0}, J: {1} ", i,j);
}

Example 4: for loop c#

//int i = 0  --  Making variable i
//i <=10     --  Making a condition for the loop to keep going
//i++        --  Increasing i by 1

for(int i = 0; i <= 10; i++)
  {
    Console.Write(i+1);
  }
/*
Output:
12345678910
*/

Example 5: c# do loop

int i = 0;

do
{
    Console.WriteLine("Value of i: {0}", i);
    
    i++;

} while (i < 10);

Example 6: c# loops

// ------------------- 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);
 }
