what if one is casted to long long and other to double

Anonymous

But duplicating code is overwhelming

what if one is casted to long long and other to double

The result of whole expression will be long long

Anonymous

why?

Anonymous

Because there are C++ rules

Anonymous

Learn about implicit type casting in expressions

Anonymous

I don't know how it's called properly

Anonymous

What led you guess that the result will be long long and not double?

Because I know how rules work

And because it's kinda obvious

Hey ... Does anybody know how to debug RE(SIGFPE) error in C program ? It's a run time error

Rashi

#include<stdio.h> int main() { int t; long long n,k,apples_per_block1=0,apples_per_block2=0,apples_in_a_row2=0; scanf("%d",&t); while(t--){ scanf("%lli %lli",&n,&k); if(n>=1&&k!=0&&n%k==0){ apples_per_block1=n/k; if(k*k>n) printf("YES\n"); else{ apples_in_a_row2=k*k; apples_per_block2=k; if(n%apples_in_a_row2==0) printf("NO\n"); else printf("YES\n"); } } } return 0; }

Rashi

#include<stdio.h> int main() { int t; long long n,k,apples_per_block1=0,apples_per_block2=0,apples_in_a_row2=0; scanf("%d",&t); while(t--){ scanf("%lli %lli",&n,&k); if(n>=1&&k!=0&&n%k==0){ apples_per_block1=n/k; if(k*k>n) printf("YES\n"); else{ apples_in_a_row2=k*k; apples_per_block2=k; if(n%apples_in_a_row2==0) printf("NO\n"); else printf("YES\n"); } } } return 0; }

This is my code . It's working fine for one test case but giving run time error (re(Sigfpe)) for another

Rashi

Any help ?

sambit

Anybody can give c tutorials

Czar

This is my code . It's working fine for one test case but giving run time error (re(Sigfpe)) for another

SIGFPE may occur due to - division by zero - modulo operation by zero - integer overflow SIFFPE is very easy to debug.

try debugging with gdb

your code doesn't seem to be printing out anything

🎩

5 int t; 6 long long n, k, apples_per_block1 = 0, apples_per_block2 = 0, apples_in_a_row2 = 0; 7 scanf("%d", &t); -> 8 while (t--) 9 { 10 scanf("%lli %lli", &n, &k); 11 if (n >= 1 && k != 0 && n % k == 0) Target 0: (teleChannelDebug) stopped. (lldb) print t (int) $5 = 16438 right now when you initialzied t like that and minus off in while loop, it's taking a long time. 3rd point mentioned by @crxz0193 I think

Rashi

Yeah I just found out that . If n is a very very large number like 160000000000000000 and k a small number like 2 then modulus operator is not working

🎩

you gotta change your loop

Rashi

you gotta change your loop

Which loop ?

Rashi

While loop ?

🎩

yep

Rashi

What's wrong in that ? And how can I correct it ?

Rashi

SIGFPE may occur due to - division by zero - modulo operation by zero - integer overflow SIFFPE is very easy to debug.

Thanks . I found those tips on Google too and now I know that third reason is the cause of this error in my case . But it's pretty difficult to debug it now

Get list of numbers in 2 arrays.find the identical integers from that 2 array and sort the final list in ascending order. Pls share the program

main.cpp:1:1: error: expected unqualified-id before numeric constant 5 int t; ^ main.cpp:2:4: error: expected unqualified-id before numeric constant 6 long long n, k, apples_per_block1 = 0, apples_per_block2 = 0, apples_in_a_row2 = 0; ^ main.cpp:3:4: error: expected unqualified-id before numeric constant 7 scanf("%d", &t); ^ main.cpp:4:1: error: expected unqualified-id before ‘->’ token -> 8 while (t--) ^~

Lol o.O

You can change long long int to unsigned lonnlong

Rashi

I have done it

Rashi

You can change long long int to unsigned lonnlong

Even that range wasn't much useful

Czar

Do you have testcase?

🎩

not sure what you're trying to achive but if your loop should always have a range. Initialize t as int. @CourageousTouch int t = 2147483648; while (t > 0) { /*code*/ t--; }

Czar

t is scanf prior to loop

🎩

oh

🎩

sorry i'm not too familiar with scanf. but is that a user input?

Czar

Yes, it's user input. Normally used in number of testcase to expect. Standard in many competitive programming website

Czar

Even that range wasn't much useful

Did you try with k=0. I see it can cause this issue

Pavel

Can you tell how does buffer works while printing anything?

I like your aspiration for details, but I can't answer this question. Pretty sure you can google it

I will google it. But, wanted to say that I find it difficult to read the documentation because it explains things that include details that I don't know at that point of time and hence I'm forced to check what that specific detail mean before learning the topic I wanted to understand.

Any recommended resources that teaches or manifest things in a smooth understandable way?
