1. If nothing else helps, look at the documetation:
For[start, test, incr, body] executes start, then repeatedly evaluates
body and incr until test fails to give True.
2. to compare the values of two expressions use ==, not =
3. Had a look at the result of Array[b,10]?? Do so.
4. To address the elemnts of a List use b[[i]] not b[i]
5. Just guessing:
b=Array[1/#&,10]
or
For[b=Table[,{10}]; i=1, i<=10, i++, b[[i]]=1/i];
??
