int detik;
int menit;
int jam;
int total_detik;
int sisa;

cout << " ======Hitung waktu====== " <<endl;

jam = total_detik / 3600;

detik = sisa % 60;

cout << " Jadi, " << total_detik << " detik adalah sama dengan " << jam << " jam " << menit << " menit " << detik << " detik ";

return 0;
}

What I have tried:

When I put the number of detik( seconds) : 3600
But the answer is not calculated. Example : Put Number of seconds : 3600. The answer of my code is [Jadi, 0 detik adalah sama dengan 0jam 0 menit 0 detik]  saya mau di saat saya meletakan angka 3600 detik. Langsung keluar [ Jadi, 3600 detik adalah 1 jam 0 menit 0 detik.
Is my course code is wrong or something? Pls help me. Thanks in advance ^_^```

What is the meaning of tittle ?
- you see nothing ?
- Result is wrong ?
- input disappear ?

I pointed out your mistake yesterday.

## Solution 1

C++
```cin="">> detik;

jam = total_detik / 3600;
sisa = total_detik % 3600;
```

You try to calculate the value of `jam` (and `sisa`) by dividing `total_detik` by `3600`. But you have never added any values into `total_detik`, so whatever results you get will not be valid. You need to rethink exactly what this code is supposed to do.

## Solution 2

Taking Richard's cue, we could try:
C++
```#include<iostream>

using namespace std;

int main()
{
int detik;
int menit;
int jam;
int total_detik;
int sisa;

cout << " ======Hitung waktu====== " << endl;
cout << " masukkan total detik :";
cin >> total_detik;

jam = total_detik / 3600;
sisa = total_detik % 3600;
menit = sisa / 60;
detik = sisa % 60;

cout << " Jadi, " << total_detik << " detik adalah sama dengan " << jam << " jam " << menit << " menit " << detik << " detik\n";

// wait for user input
cin.ignore(256, '\n');
cin.get();
}```

## Solution 3

Quote:

In your question you didn't told if answer is wrong or if nothing is printed or if screen is cleaned before you see what the program printed and if it printed anything.
- add checkpoints in your program, to ensure the execution reached certain point.
C++
```#include<iostream>

using namespace std;

int main()
{
int detik;
int menit;
int jam;
int total_detik;
int sisa;

cout << "Checkpoint: Program Start";
cout << " ======Hitung waktu====== " <<endl;
cout="" <<="" "="" masukkan="" detik="" :";
="" cin="">> detik;

jam = total_detik / 3600;
sisa = total_detik % 3600;
menit = sisa / 60;
detik = sisa % 60;
cout << "Checkpoint: Calculation done";

cout << " Jadi, " << total_detik << " detik adalah sama dengan " << jam << " jam " << menit << " menit " << detik << " detik ";

cout << "Checkpoint: Program End";
return 0;
}```

- Use the debugger to investigate what is going on in your program.
Your code do not behave the way you expect, or you don't understand why !

There is an almost universal solution: Run your code on debugger step by step, inspect variables.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't know what your code is supposed to do, it don't find bugs, it just help you to by showing you what is going on. When the code don't do what is expected, you are close to a bug.
To see what your code is doing: Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

When I put the number of detik(second) :3600
What should I do 😭 I'm still newbie

Use Improve question to update your question.
So that everyone can pay attention to this information.

So learn the debugger, or read caredukky other solutions.

## Solution 4

```#include<iostream>

int detik;
...
int total_detik;
...
cin="">> detik;

jam = total_detik / 3600;
sisa = total_detik % 3600;
menit = sisa / 60;
detik = sisa % 60;

cout << " Jadi, " << total_detik << " detik adalah sama dengan " << jam << " jam " << menit << " menit " << detik << " detik ";

return 0;
}```
Between declaring it and using it's content, you don't give `total_detik` any value at all.
You read a value into `detik`, but you don't use it!
Try changing this line:
`cin >> detik;`
To this:
`cin >> total_detik;`
And see what happens.

To be honest, if you'd followed the advice you were given ages ago and used the debugger, you would have seen exactly what was going on.
The debugger is your friend: it's much faster than asking others to solve it for you ...
