QuestionIf element in diagonal is 1 then its unit matrix , else it's not unit matrix [modified] PinmemberAsad JOgi11-Nov-12 20:26 
AnswerRe: If element in diagonal is 1 then its unit matrix , else it's not unit matrix PinmemberTorstenH.11-Nov-12 22:15 
I assume you do not get it to work.
 
As this looks much like a homework, I'll give you some tips but no solution.
read them, follow them and you'll find the right way:
 
- variable names always start with lower case
always. ALWAYS. Please rename "ArrayMatrix" to "iArrayMatrix". Copy it and set up a second Array for testing.
You can comment them in/out by using Strg+7 in any IDE.
 
- use clear names
"i" and "j" are common counters. But how about "iRow" and "iCol" ? Those give you much more control on what is happening.
 
- delete "l"
No. One does not put the length of an Array in a variable. Simply NO.
 
- I think this homework is about recursion. Read about that on the web. That would need some methods - is this topic already introduced in class? can we use some?
 
- one boolean "bIsMatrix" should be enough. give it a init value "false" and use the loops to set it to true when you find a value "1" in the diagonal. Set it "false" if not. Read "bIsMatrix" after the loops to present result.
