Also, we have a requirement to be able to build with clang and libc++ (for Android builds) and well the support there is really bad for now

Do you build IOS apps?

Ahh I thought there was something interesting

you work on building compilers?

#include<iostream> using namespace std; void merge(int *arr,int l,int mid, int r ) { int n1=mid-l+1; int n2=r-mid; int arr1[n1],arr2[n2]; int index=l; for(int i=0;i<n1;i++) { arr1[i]=arr[index++]; } index=mid+1; for(int i=0;i<n2;i++) { arr2[i]=arr[index++]; } int i1=0,i2=0,k=l; while (i1<n1&&i2<n2) { if (arr1[i1]<arr2[i2]) { arr[k++]=arr[i1++]; }else { arr[k++]=arr[i2++]; } } while (i1<n1) { arr[k++]=arr[i1++]; } while (i2<n2) { arr[k++]=arr[i2++]; } } void merge_sort(int *arr,int l,int r) { if(l>=r) { return; } int mid=(l+r)/2; merge_sort(arr,l,mid); merge_sort(arr,mid+1,r); merge(arr,l,mid,r); } int main() { int arr[8]={7,2,12,0,5,3,7,6}; merge_sort(arr,0,7); for (int i = 0; i < 8; i++) { cout<<arr[i]; /* code */ } return 0; }

#include<stdio.h> int main() { int yos; char g,qual,X; printf("enter years of service:"); scanf("%d",&yos); printf("enter gender and qualification:\n"); scanf("%c%c",&g,&qual); (g=='M'&&yos>=10&&qual=='P'?printf("15000"):g=='M'&&yos>=10&&qual=='G'||g=='M'&&yos<10&&qual=='P'?printf("10000"): g=='F'&&yos>=10&&qual=='P'?printf("12000"):g=='F'&&yos>=10&&qual=='G'?printf("9000"):g=='F'&&yos<10&&qual=='P'?printf("10000"): g=='F'&&yos<10&&qual=='G'?printf("6000"):X); return 0; }

That last one is meant to be called inside the function, I guess I'll just make an overload without that argument and call this function with an empty lambda as obs

#include<stdio.h> int main() { int yos; char g,qual,X; printf("enter years of service:"); scanf("%d",&yos); printf("enter gender and qualification:\n"); scanf("%c%c",&g,&qual); (g=='M'&&yos>=10&&qual=='P'?printf("15000"):g=='M'&&yos>=10&&qual=='G'||g=='M'&&yos<10&&qual=='P'?printf("10000"): g=='F'&&yos>=10&&qual=='P'?printf("12000"):g=='F'&&yos>=10&&qual=='G'?printf("9000"):g=='F'&&yos<10&&qual=='P'?printf("10000"): g=='F'&&yos<10&&qual=='G'?printf("6000"):X); return 0; }

Turnery operator says, both the side of : there should be equal typo operations, In the last case, print : X both are different so, it wont work. that should be the error I guess

#include<stdio.h> int main() { int yos; char g,qual,X; printf("enter years of service:"); scanf("%d",&yos); printf("enter gender and qualification:\n"); scanf("%c%c",&g,&qual); (g=='M'&&yos>=10&&qual=='P'?printf("15000"):g=='M'&&yos>=10&&qual=='G'||g=='M'&&yos<10&&qual=='P'?printf("10000"): g=='F'&&yos>=10&&qual=='P'?printf("12000"):g=='F'&&yos>=10&&qual=='G'?printf("9000"):g=='F'&&yos<10&&qual=='P'?printf("10000"): g=='F'&&yos<10&&qual=='G'?printf("6000"):X); return 0; }

I have this function: template<typename stepper_type, typename system_type, typename state_type, typename scalar_type, typename observer_type> int integrate(stepper_type stepper, system_type sys, state_type x, scalar_type t0, scalar_type dt, int Nsteps, observer_type obs){ //stuff } I want the last argument to be omitable, how can I achieve that?

You could do something like: template<typename stepper_type, typename system_type, typename state_type, typename scalar_type, typename observer_type = decltype([](){})> int integrate(stepper_type stepper, system_type sys, state_type x, scalar_type t0, scalar_type dt, int Nsteps, observer_type obs = observer_type()){ //stuff } Just remembered that this would work only in C++20 but. Lambda expressions are not allowed in unevaluated contexts before C++20. So this code will not compile on C++17.

Why you want nested ternary ? It's bad practice

Im a beginer thats why im trying to solve any question with every possible way to learn

Use if-else instead, ternaries are unreadable and very easy to do wrong

I'd replace the lambda with the simplest std::nullptr_t

Will a long-integer work on a 32 bit system is there an any relation between 32 bit data type and 32 bit system?

Hello friends, I hope you are all well. I'm going to ask you a question that I know is typical of people without programming knowledge, but let me explain the context. I already know programming in PHP and JavaScript, also in C and C++ although I am a beginner in these two. Now, at the university I must focus on one of the two, and I ask you this question so that it can be answered from a personal point of view, which one would you focus on? , C or C++ and why? Sorry if my english it's not perfect.

I would definitely go for C++, after all you will be able to understand C as well. My first job in programming was actually related to C back then we were developing operating system, I absolutely hated it every single day. And quite soon I changed the company and started working with C++ till the day. To be honest don’t just focus on language, it’s just a tool, focus also on architecture and other technologies definitely work on understanding how cmake works, shell scripting abilities, python and perhaps at least basic understanding of ruby and quite soon you will be in well payed position

Depends on what you wanna do. If you wanna work on researching low-level stuff and performance is something very important, go with C, C++ or Rust. If not, Javascript is enough

If you want to learn C too (our brains has such a capacity to know more than one language!), I recommend the program (7 courses) “C and Linux” from Dartmouth Univ. at EdX.org; the free version enable you to do all the exercises, except the last one. I stayed out from the comp science world, returned by “remembering” C with this course and it was a really good thing for me.

But, of course, C++ is a superset of C.

Yes, this is clear to me. but since the university requires me C or C++, that's why the question of deciding one or the other for now. JavaScript it's for continue work on web developing, this is other thing to me.

C++ is going to be easier than C

But, of course, C++ is a superset of C.

Yes, that's how I understand it. You can even understand C, knowing C++

No

Actually, its

Hard to understand and hard because need extra works is different

In c even the basic stuff (like String manipulation) need to be done from scratch or go and find a good library for something

#include<iostream> using namespace std; #include<set> int main(){ set<int> s{1,2,3,4,5,56}; auto it=s.lower_bound(3); cout<<it-s.begin(); }

i think we can use distance function to get the index

It will give you the number of steps required to reach one iterator fromthe other as long as one is reachable from the other. But that is not equivalent to index. Sets don't store elements in the order of insertion. Moreover a new insertion can affect how the elements are located. So you should not be doing this. If you need indexes, use a container that is relavant for that usage

Anyone know any other projects like: libsrt, safeclib, datatype99 or libcello?

Yes C++

I meant something good

C is not good :)

right. it isn't just good it is the greatest.

c with classes sounds good

You can still write c in c++

what makes c++ appealing is it has everything so software development is easier, but everything has cost to it.
