Share Mistakes that you would have done while learning programming.

Question

share your mistakes that you may have done while learning programming so it can help other they would not repeat it...

Also share some tricks to Novice Programmers learning Programming.

Answer 1

I think everyone done this at least once or something similar inside a function...
if (x == y) {
return true;
} else {
return false;
}
instead of...
return x == y;

Answer 2

#1:not a mistake,but it makes code unnecessarily long
if(aBoolean){
//doStuff
}
else{
//doOtherStuff
}
when you could use::
aBoolean?doStuff:doOtherStuff;
#2
thinking
if(x=2){
//dostuff
}
is same as
if(x==2){
//dostuff
}
#3:lastly,poor use of arrays
person1="Tim"
person2="bob"
person3="dave"
pe...haa its annoying,
when u could use::
person=["Tim","bob","dave"]
Well this were my beginner mistakes and theyre quite common,hope i helped

Answer 3

char foo[5] = "Hello";

Experienced C/C++ programmers will see the problem. I didn't at that time. I just deleted the project.

Or my very first error I've written (Java):

public class HelloWorld {
System.out.println("Hello world!");
public static void main(String[] args) {

}
}

The book author said I should just "place it in there".

My only advice: Read books and practice.
