with vb instead?

i mean, why should one choose to use c++ instead of c#?
klimi
i mean, why should one choose to use c++ instead of c#?
uh.... because they know c++ already or they want to learn it... or they have team which uses that language... or they don't want to deal with outdated mono/dotnet
tb
what do you mean with "to deal with outdated mono/.net"?
Abdelrhman
I need help please
klimi
the last version which mono supports is like 5

with c# may i do gui apps on linux?
Like @K11M1 said it is possible to do GUI development with C# on Linux but I am not sure why you would do that. And @K11M1 already mentioned about Mono not supporting the latest version of .Net core or C#. Your original question was about Windows and that is what my reply pertains to

I've understood,
but about the first book to read to learn c++ which do you personally think would be the best one for a person who has never programmed seriously and who is an absolute beginner who doesn't know almost anything? (I've already read the stackoverflow page, but there are anyway too many choichable books 😅)

What about divide-and-conquer algorithms based like quiksort in the question of stack smash event? This can heapens or not?

Hi guys, how can I give an infinite loop to my switch case code
The program should continue until the user selects exit.

Write a program of school reservation which ask a user to enter
(name, educational level) Where tuition fees:
▪ Nursery
10000
▪ Primary
15000
▪ Preparatory
▪ Secondary
20000
22000
There is a discount for brothers, if 2 brothers add discount 10%, more than 2, the discount reach to 15%. Note: discount percentage on the total.
Print out
1. Register for three brothers (nurseray&2primary), print the cost.
2. Register for two brothers (primary & secondary), print the cost.
4. A number of students in every level.
3. Register for three brothers (nurseray&2 preparatory), print the cost.

I need some help to write the project
Abdelrhman
It's c++
klimi
I am asking what you need help with
klimi
So what's the problem you need help?
Abdelrhman
I try but I can't solve it
Abdelrhman
Can anyone will help me?
klimi
You haven't even stated your problem clearly... Saying "I tried and it doesn't work , wrote it for me" doesn't say anything informative
Abdelrhman
I'm really tried
Abdelrhman
But it doesn't work
klimi
I'm really tired too
klimi
Well that's too bad that it doesn't work
Abdelrhman
I think there are some error in code
klimi
As I said, if you won't state the problem clearly anyone will be hardly able to help you

This is my solve

Discount is an integer Instead of a double/float...... You can't divide integer 15 by 100 to get 0.15....
CALVIN
totalCost*discount/100; cout<<finalCost<<<endl;
Would be more better if you introduced brackets here👆

Hey guys,
I wanted to know that how can I get an string from user without length limit in C?
I'll really appreciate it if you write the code piece too 🙏🏻.

What do you mean "without length limit"?

i didnt wrote on c for more than year but as i know this works

char* str;
gets(str);
Never use gets. It's unsafe and even was removed from C++ for that reason. And your implementation without allocation will cause undefined behavior.

We can use fgets

fgets(string,lengthofstring,stdin);

allocate with a start value and reallocate as soon as the string goes up to the initial max length

Hi everyone
I have cloned a source code from github and it contains a Makefile in it and as I searched for I realized that for using from Makefile I should run "make" in terminal and I got these errors that doesn't find clang but I have installed clang before. Can you please help me?
make -C third_party/SVDLIBC
make[1]: Entering directory '/home/aryas/Desktop/anchor/third_party/SVDLIBC'
clang -Wno-deprecated-writable-strings -O3 -c main.c
make[1]: clang: No such file or directory
make[1]: *** [Makefile:11: main.o] Error 127
make[1]: Leaving directory '/home/aryas/Desktop/anchor/third_party/SVDLIBC'
make: *** [Makefile:56: third_party/SVDLIBC/libsvd.a] Error 2
Aryas
edit the makefile and switch clang for g++ or one that you already have
I did it before but it didn't work but thanks for replying
coal
sadness
coal
the makefile is broken or the context you're running it in does not provide a path
Aryas
yeah it could be. I'll check this. Thanks
