addition help

i'm trying to make a code which calculates the sum of 1+2+3+4+5+6.....+98+99+100... i tried 2 make the program but it doesn't work... plzz tell me what is my mistake...

code:

var num: int num:= 0 for i: 1..100 num:= 0+i end for put num

[CodeMonkey2000]

num should equal zero, and num shoud be increasing by i. In other words, num equals num plus i.

And in Turing...

code:

var num: int := 0 for i: 1..100     num += i end for put num

or

code:

put n * (n + 1) div 2

where n is the ending number
