The generic view of a loop is   for  initialization  condition  increment-decrement     The first part initializes the code   The second part is the condition that will continue to run the loop as long as it is true   The last part is what will be run after each iteration of the loop  The last part is typically used to increment or decrement a counter  but it doesn t have to

for  int i   0  i  lt  8  i      It s a for loop  which will execute the next statement a number of times  depending on the conditions inside the parenthesis      for  int i   0  i  lt  8  i      Start by setting i   0     for  int i   0  i  lt  8  i      Continue looping while i  lt  8      for  int i   0  i  lt  8  i      Every time you ve been around the loop  increase i by 1   For example   for  int i   0  i  lt  8  i        do i     will call do 0   do 1       do 7  in order  and stop when i reaches 8  ie i  lt  8 is false

for  int i   0  i  lt 8  i          code    In simplest terms  int i   0  if  i  lt 8    code i   i   1    i   1 if  i  lt 8    code i   i   1     i   2 if  i  lt 8    code i   i   1     i   3 if  i  lt 8    code i   i   1    i   4 if  i  lt 8    code i   i   1    i   5 if  i  lt 8    code i   i   1    i   6 if  i  lt 8    code i   i   1    i   7 if  i  lt 8    code i   i   1    i   8 if  i  lt 8    code - this if won t pass

for  lt first part gt    lt second part gt    lt third part gt         DoStuff        This code is evaluated like this    Run  lt first part  If  lt second part  is false  skip to the end DoStuff    Run  lt third part  Goto 2   So for your example   for  int i   0  i  lt  8  i          DoStuff         Set i to 0  If i is not less than 8  skip to the end  DoStuff    i   Goto 2   So the loop runs one time with i set to each value from 0 to 7   Note that i is incremented to 8  but then the loop ends immediately afterwards  it does not run with i set to 8

it s the same as think the next    starting with i   0  while i is less than 8  and adding one to i at the end of the parenthesis  do the instructions between brackets   It s also the same as   while  i  lt  8            instrucctions like      Console WriteLine i       i        the For sentences is a basis of coding  and it s as useful as necessary its understanding   It s the way to repeat n-times the same instrucction  or browse   or do something with each element  an array

That s a loop that says  okay  for every time that i is smaller than 8  I m going to do whatever is in the code block  Whenever i reaches 8  I ll stop  After each iteration of the loop  it increments i by 1  i     so that the loop will eventually stop when it meets the i  lt  8  i becomes 8  so no longer is smaller than  condition   For example  this   for  int i   0  i  lt  8  i         Console WriteLine i       Will output  01234567  See how the code was executed 8 times   In terms of arrays  this can be helpful when you don t know the size of the array  but you want to operate on every item of it  You can do   Disclaimer  This following code will vary dependent upon language  but the principle remains the same  Array yourArray   for  int i   0  i  lt  yourArray Count  i          Console WriteLine yourArray i        The difference here is the number of execution times is entirely dependent on the size of the array  so it s dynamic
