Theory is required. Otherwise you cannot explain to yourself how things work. You may know how to use pointers, but you may not know how they work and when you run into problems you cannot figure out what is wrong.
This is so true

What are opinions about freecodecamp?

Off topic. Github pages or gitbooks for personal blogs coding and stuff ?

Please Help me out .How to debug this error and please also explain me .Below the piece of code I had pasted the error message as well. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ ++ int numberOfOccuence(int Array,int x){
int count=0;
for(int k=0;k<10;k++){
if(Array[k]==x) count++;
}
return count;
} ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ prog.cpp:20:35: error: invalid conversion from 'int*' to 'int' [-fpermissive]
cout<<numberOfOccuence(Array,x);
^
prog.cpp:4:5: note: initializing argument 1 of 'int numberOfOccuence(int, int)'
int numberOfOccuence(int Array,int x){ https://pastebin.com/mLhgmGaG

error is clearly specified

read it
Siddharth Sahoo
int* to int [-fpermission ] what does this mean ?
Siddharth Sahoo
datatype is miss matched while conversion ?
Siddharth Sahoo
But how to debug this?
Anonymous
First of all, use of 'Array' does not match to what is in function parameters
Anonymous
It's not actually an array
Anonymous
Siddharth Sahoo
It will take array elements as input.

Can you answer my question?

I'm not sure I follow you there. Can you tell me what is "first iteration"?
Anonymous
You don't seem to want to figure out what's wrong with your code
Anonymous
You just wanted someone to fix the code for you
Siddharth Sahoo
Can you answer my question?
It will take input from the user and will store the input value to the ith index of an array.

Siddharth Sahoo
Yeah, that's what I did wrong. I should be writing it as int *Array or int Array[] .Now I know.

Also, 21 line is also wrong. Keep in mind.

Uh

Sorry. Congratulations.

Thanks Roman, for helping me out.

Can you help me out in one more thing. Lately I was submitting my solution to SPOJ .This is the question https://www.spoj.com/problems/BSEARCH1/ and I wrote this as my problem solution and it is working fine on my code blocks compiler but unable to get accepted on the SPOJ and stating to be runtime error. Can you give a look to the code. https://pastebin.com/j035fMCX
Siddharth Sahoo
Is it some contest?
No. No. It is not a contest. Do check the problem link, You will also get to know that it is just a simple problem question.I have some other code solution as well on my hand from my friend and it is almost similar to my code. But as I said it is unable to get accepted by SPOj.

I'm sorry😭😭

What if there's more than 100 elements given?
Siddharth Sahoo
What if there's more than 100 elements given?
Yeah...Even the constraints of the problem say 0 < N <= 10^5. And if accordingly I make an array with 100000 size. It says the Time exceeded. I did int arr[100000] but no help.

You can use std::vector and resize it dynamically
Siddharth Sahoo
Help me out I don't know about this std:vector and all.
Pavel
Help me out I don't know about this std:vector and all.
Here's documentation
https://en.cppreference.com/w/cpp/container/vector
If something is unclear google it, if it doesn't help then ask with details (what exactly is not clear/not working)

Help me out I don't know about this std:vector and all.
Use it as vector and if you want to add last item do vector.push_back(item)
Pavel

This. And I would suggest to call reserve as far as it's future size is known.
klimi
This. And I would suggest to call reserve as far as it's future size is known.
I don't know that... Thats cool
klimi
Is it like flag?
Pavel
Yes it is just a simple binary Search .
Also, I think there's something with the algorithm itself, because if it's the binary search then why you have the second for loop. It feels like you're doing it linearly. But it looks even stranger

while(left<=right){
mid=(left + right)/2;
if(array[mid]==query) {
result=mid;
break;
}
else if(array[mid]>query) right=mid-1;
else left=mid+1;
}
cout<<result<<endl;
} No it was binary search. See.
Pavel

This allocates chunk of memory that can hold the asked amount of elements.
So when you do push_back it doesn't call for additional reallocations
klimi
Yeag
klimi
I know how storing stuff In memory works
klimi
Its pretty clever to have such function
Pavel

while(left<=right){
mid=(left + right)/2;

result=mid;
break;
}
else if(array[mid]>query) right=mid-1;
else left=mid+1;
}
cout<<result<<endl;
} No it was binary search. See.
Ok, seems I got it. It searches for m elements right?
Anonymous
Or just use realloc.
However it requires some experience with the allocated storage duration and is used in C. Using vectors would be much simpler way.

Did you go through the first link. In this problem it is searching the element inside the array m number of times. We have to search m numbers inside the array, if they exist we will print the index and if it doesn't it will print -1.
Pavel

Its okay. You don't need to be sorry for anything.I guess that's why we are here to learn and adopt new good habits.

Hi. A have strange error with my project

Maybe i shoul manyally set order of obj file should linking?
n1coc4cola
what's the ide you use?
n1coc4cola
If you use Qt, you can have some errors with the library of the others or somethings which works not as you want
n1coc4cola
I had a problem of linking objects (like you) when I wanted to compile it in the ide of Qt
n1coc4cola
Nox, I run the commands manually and I have no problem
n1coc4cola
maybe you should do this (for me it was with the 'make' command)
