Good evening everyone, I’ve been stuck on this problem for a while. I’m supposed to put 3 void functions one for inputting and one for getting the max numbers between 2 arrays and the last one is for printing the array I just got with my function, the input and output parts are manageable but the max numbers one is out of my level atm all I get is garbage data so I could use some help

Can you provide your code? At least of the function that works incorrectly

Can you provide your code? At least of the function that works incorrectly

#include <iostream> using namespace std; void inputArray(int array1[5], int array2[5]); void maxArray(int array1[5], int array2[5], int arraym[5]); void PrintArray(int array[]); int main() { int a[5]; int b[5]; int m[5]; inputArray(a, b); maxArray(a, b, m); PrintArray(m); } void inputArray(int array1[5], int array2[5]) { int i; cout << "enter values for the first array: \n"; for (i = 0; i < 5; i++) cin >> array1[i]; cout << "enter values for the second array: \n"; for (i = 0; i < 5; i++) cin >> array2[i]; }; void maxArray(int array1[5], int array2[5], int arraym[5]) { int i; int max = 0; for (i = 0; i < 5; i++) { if (arraym1[i] > array2[2]) max = arraym[i]; } }; void PrintArray(int array[]) { cout << "the values of the array are: \n"; for (int i = 0; i < 5; i++) cout << array[i] << " "; }

I would've earlier but unfortunately you can't share photos in here

Fortunately, because now I can copy it to an online compiler to investigate

#include <iostream> using namespace std; void inputArray(int array1[5], int array2[5]); void maxArray(int array1[5], int array2[5], int arraym[5]); void PrintArray(int array[]); int main() { int a[5]; int b[5]; int m[5]; inputArray(a, b); maxArray(a, b, m); PrintArray(m); } void inputArray(int array1[5], int array2[5]) { int i; cout << "enter values for the first array: \n"; for (i = 0; i < 5; i++) cin >> array1[i]; cout << "enter values for the second array: \n"; for (i = 0; i < 5; i++) cin >> array2[i]; }; void maxArray(int array1[5], int array2[5], int arraym[5]) { int i; int max = 0; for (i = 0; i < 5; i++) { if (arraym1[i] > array2[2]) max = arraym[i]; } }; void PrintArray(int array[]) { cout << "the values of the array are: \n"; for (int i = 0; i < 5; i++) cout << array[i] << " "; }

if (array1[i] > array2[2]) { max = arraym[i]; } What do you expect this code to do? You set max to a value from arraym[i], but the values of your arraym are not initialized

did you want to do something like arraym[i] = std::max(array1[i], array2[i]);?

if (array1[i] > array2[2]) { max = arraym[i]; } What do you expect this code to do? You set max to a value from arraym[i], but the values of your arraym are not initialized

I’m a bit sketchy on arrays but the purpose I think is to compare the values of array1 and array2 which I initialize in the first function, if the value of array1 is less than the one in array2 it skips it

yes, but you assign an uninitialized value to max and you never use this max. and even if you used it, not sure what could it give I mean, can you tell, what should be a result of your maxArray function? should it be an int of the max element from two arrays? or should it be an array that contains max elements on all the positions from these two arrays?

Because now it feels like you tried to do both half way

My only reference for this problem is the max for a single array which I can do, the point here is an array that contains the max elements of the two arrays entered

But I don’t know what to replace the variable max with for it to store the new array in somewhere to print it

void maxArray(int array1[5], int array2[5], int arraym[5]) { for (int i = 0; i < 5; i++) { arraym[i] = std::max(array1[i], array2[i]); } } So, something like this you mean?

Yes exactly, but now the problem becomes how do I compare the elements of a1 and a2 to determine which one is the biggest

Yes exactly, but now the problem becomes how do I compare the elements of a1 and a2 to determine which one is the biggest

if (array1[i] > array2[i]) { cout << "1 is bigger"; } else if (array2[i] > array1[i]) { cout << "2 is bigger"; } else { cout << "equal"; }

Man what a legend, I’m new to c++ so I don’t know all the functions correctly but the std::max worked like a charm

Thank you mr. Pavel

good, do you want suggestions/advises about how you can improve the code you've sent?

Can I do it without the function max?

Can I do it without the function max?

yes, with the code above, something like this if (array1[i] > array2[i]) { arraym[i] = array1[i]; } else if (array2[i] > array1[i]) { arraym[i] = array2[i]; }

Wow

Where Does knowledge like this come from

I’ve been stuck for about 2 hours trying to solve it

Can you tell me what's wrong with this written code?

You have great documentation and tutorials, a lot of people here learn on their own and so can you.

I would help you with software setup though

Has anyone here read "C Primer Plus"?

Yeap i can learn on my own all i need is just guidance

i suggest to start with something simple - not c / cpp

python lets go

LoL

python lets go

Sure

Tcl

Sure

i mean that's what i did dont know if it's recommended lol

python then C/Cpp

Tcl

huh

huh

Chad language. Has great interaction with C. The author also wrote Tk, of which the Python binding is called Tkinter

i mean if ya wanna start to get around programming like the math and logic stuff python should be great?

python basics and questions then head to C/Cpp ig?

What's simple?

lmfao

What's simple?

tbh nothing is simple if you wanna dive into it, but there are some programming languages that looks simplres and more understandable than others like python, javascript, nim, ... i suggest to start and then switch on other languages if you want

Hi Guy's

Hello eve

i have a question about 2D vectors in CPP

void Board::resizeBoard(uint row , uint column,Direction direction) { if (direction == Horizontal) { setRow() = max(row ,getRow()); setColumn() = max (column,getColumn()); this->board.resize(getRow(),vector<char>()); this->board[row - 1].resize(column,'_'); } }

I have an assignment and the require is to build Dynnamic Board

if i want to insert a word in [0,0] and after that in [3,5]

i need to initialize all the "rows" between them?
