#include <iostream>
using namespace std;
int main()
{

int n,t;
cin>>t;
for(int i=0;i<t;i++)
{  
int a,b,c;
cin>>a>>b>>c;
 c=a*b;
if(c%4==0)
{
  cout<<(c/4)<<endl; 
}
else 
{
cout<<((c=c/4)+1)<<endl ;
}
}
}
``` the problem in this code is when i edited cin>>c above it gave me my desired output , i wanna know what was the problem internally in it

Why ask the user to enter c when on the next line its value is overwritten with a*b?

#

How about posting examples of input and expected output?

spice warren How about posting examples of input and expected output?

1 5 3
2 6 3

Your input/output is difficult to understand.
Mind putting it between ```?

4
2,1,5
expected: 1
observed: 3
2,6,3
expected: 3
observed: 4
3,4,5
expected: 3
observed: 5
4,5,7
etc.

How to Format Code on Discord

• type three "backticks" (not quotes/apostrophes, on QWERTY layout, left of 1-key)
• on the same line, type the file extension for that language (c or cpp)
• enter your code on a new line and put another three backticks at the end

Example Input

```cpp
int main() {
return 0;
}
```

Example Output

int main() {
    return 0;
} ```
