What is the best
C or C++

i'm learn c cuz l need more information

Consider int val=0xFACE; Write expressions using bitwise operators that do the following:
A. test if atleast three of the last four bits (LSB) are on
B. reverse the byte order (i.e., produce val=0xCEFA)
C. rotate four bits (i.e., produce val=0xEFAC)
Abhishek
Unable to solve b part

Abhishek
Ok thanks sir
Artöm
Use shifts and ors
Abhishek
I took 12 instead of 4
Abhishek
Abhishek
Not getting correct output for bpart
Abhishek
@das_3sz3tt
Artöm
Is it B?
Abhishek
No it consists all 3 three part
Abhishek
The int bpart variable is the b ques

why int?
according to ISO9899 standard, int type might be limited from -32767 to 32767, but unsigned int is guarateed to store up to 65535

It may be 32 bits in ones compilers inplementation

Why 4 then? You need to move bytes around, not half bytes

I know. When you can write a program that is independent of implementation, why are you writing for a specific implementation?
Artöm
Because thats simple non-production task which doesnt give a shit about sizeof int
Abhishek
So should I use unsigned int
Abhishek
❓
Artöm
Yes
Abhishek
Ok
Artöm
unsigned is good for bit stuff
Abhishek
Done thank u very much

Can someone helps me out creating a function for reading files. Function should contain arguments, in this case passing the file path and should return content of a file as a string. I know JAVA pretty well, but now I have to do some small C++ lib for my Android app, so it's like first time trying C++.
Thanks

Have you heard name C-- language?
Nomid Íkorni-Sciurus
Have you heard name C-- language?
it is a language that the GNU compilers suite use as intermediate between the source and the actual assembly.

Let me guess
You are learning C++ through Android development
Anyway
Here is the code
#include <fstream>
using namespace std;
string readFile(const char* filename){
ifstream in(filename);
string text;
while(in.good()){
string temp;
getline(in, temp, '\n');
text += temp;
}
return text;
}
My Hope
Guys pls tell me is there any c+++ app for mobile android
MᏫᎻᎯᎷᎷᎬᎠ
Yeah
Don't prefer to use "using namespace std"
MᏫᎻᎯᎷᎷᎬᎠ
I just didn't want to write much

}
Well im not learning, im just forced now to create a lib.
Thanks for the code.

You are welcome

the '\n' should be the FILE* to read from

Hey

hello. I need help to know my error. This is the code i wrote to check if any two elements in the same row of a matrix are equal. If the element is '0' i dont want it to check.However this code shows segmentation fault whenever the if condition becomes true.
for(int i=0;i<no_hours;i++){
for(int j=0;j<no_rooms;j++){
if(houroom[i][j]==0)
continue;
for(int k=(j+1);k<no_rooms;k++){
if(decrypt(houroom[i][j])==decrypt(houroom[i][k])){
cout<<".";
check_avail(i,k);
}
}
}
}

i learnt on the web that segmentation fault is due to bad allocation of memory but how does that fit here?

It looks I or J are larger than your array and you're getting out of bound error

And I don't understand what the second loop is supposed to be. It starts from the end of the array and increases afterwards? 🤔

Thankyou @dunklecat and @JRandomGuy but the problem was somewhere else and i was uselessly staring at that bit.
Its' solved now.
