I'm trying to solve the 'nilai' was not declared in this scope error which uses array and it happens at line 35, so please fix some thing to make work again and generate maximum number between numbers in an array (and minimum number, but it not included yet). Please be quick ASAP due my homework is due 4 hours left as i created this help forum. The code will be included below. Thank you

can you share the actual code ? 😅

ah wait, you where already on it

i using geany btw because my univ use it for practice usage

well, if you want access to nilai, you need to pass nilai to the function

like?
@lost scaffold this maybe? https://www.w3schools.com/cpp/cpp_function_array.asp

I also highly reccomend not using W3 school or G4G they are both pretty bad for C(++)

also is there a specific reason you forward declare max instead of just putting max above main?

i would complain more about global namespace variables than about forward declared func

oh yeah thats another point
uncut olive
what does mean and how to fix it?

your forward declaration says the function will be of the signature int(float, int*)
but your actual function definition has the signature int(float*, int*)
also im not seeing the 'nilai' was not declared in this scope error you talked about in the error list at the bottom of the screenshot

because i fixed it

int i = 0;
for(i=1; i<jumlah; i++){

return v;
}
what is V supposed to be? an why are you passing it in as a pointer pointer?
wise drift
this is so hard to debug when i dont know what these jumlah and all words mean, like when i dont know what the problem statement is
uncut olive
these words are comes from indonesian
wise drift
but it looks like the program is compiling ?
uncut olive
should i tell you my homework?
wise drift
yes , a problem statement will be very helpful

Buatlah sistem penilaian untuk mahasiswa dimana diawal kita input nama dan nilai mahasiswa, lalu di outputkan semua nilai dan stringnya dan diakhir dikasih statistik penilaian nya contoh:
===== Program Pengolahan Nilai Mahasiswa =====
Masukkan jumlah mahasiswa: 3
--- Data Mahasiswa ke-1 ---
Masukkan Nama: Budi
Masukkan Nilai: 85
--- Data Mahasiswa ke-2 ---
Masukkan Nama: Ani
Masukkan Nilai: 92
--- Data Mahasiswa ke-3 ---
Masukkan Nama: Chandra
Masukkan Nilai: 78
=======================================
--- Hasil Pengolahan Data ---
Daftar Nilai Mahasiswa:
-
Budi : 85
-
Ani : 92
-
Chandra : 78
Statistik Nilai:
Nilai Rata-rata : 85.00
Nilai Tertinggi : 92 (Diraih oleh: Ani)
Nilai Terendah : 78 (Diraih oleh: Chandra)
Here the english translation:
===== Student Score Processing Program =====
Enter the number of students: 3
--- Student Data 1 ---
Enter Name: Budi
Enter Grade: 85
--- Student Data 2 ---
Enter Name: Ani
Enter Grade: 92
--- Student Data 3 ---
Enter Name: Chandra
Enter Score: 78
=======================================
--- Data Processing Results ---
Student Score List:
1. Budi : 85
2. Ani : 92
3. Chandra : 78
Grade Statistics:
Average Grade : 85.00
Highest Grade : 92 (Achieved by: Ani)
Lowest Grade : 78 (Achieved by: Chandra)```also using function on my programs would get a bonus points for the task

@uncut olive i believe the above program is the debugged version of the code you sent
uncut olive
yes
okei, i'd try this
anyways can you show me which website to compare 2 diff codes?
wise drift
okei, i'd try this
there are few things you should do and dont do in general when writing code
- Dont use the line
using namespace std;at the top of your code , writestd::coutandstd::cinexplicitly , its not that hard - You cant make an array which is dynamically sized on the stack , instead look into making one on the heap using the
newkeyword. You tried to do something likestd::string names[variable], you cant do that. (or if they have taught you whatstd::vectoris , use that instead) - As you previously saw , having seperate declarations can mess with you , just define your functions at the top
- Revisit what pointers are and how they are pased as arguments and how they are used , your original code looked like you are confused about how to use the properly
