well, it's hard to get rid of bad practices and habits especially if you learn them from the beginning

very true

hence, I don't think "It's not good" was related to sharing the project but rather to the quality of the code

i didnt look at the code, but sometimes seeing an example of something you are trying to use is extremely beneficial

just thought it was funny that an example given for file I/O was thwarted away cause its bad

but especially when it comes to IO it's crucial to know what you're doing

otherwise things like heartbleed occur

open file, capture stream or FD, use file, close file

he gave an example of how he was using those operations on a larger scale

It's a good example because his code contains a lot of bad practices

1. The whole code placed in the ONE file

I didnt say it wasnt good practice. I said it's an example of using files

2. He uses std::cout and std::cin directly

3. The logic and the input tied to each other

I didnt say it wasnt good practice. I said it's an example of using files

When you're beginner, it's hard to distinguish whether the code is good or bad

Can someone help me on how to write a cpp function that combines addition,subtraction and multiplication

How to read 2 line of input string as a single string

2*std:: getline and concatenate

Is there any predefined things were available for that

Yes

What is the error in the (for)?

Yes, It also happens quite a bit in Africa, and I still think some cranky teachers in universities elsewhere still use it

Where do they get hardware for it, for turbo c and dos?

What is the error in the (for)?

index out of bounds

[C++20] Library: mutable constexpr expression for clang 9.0 and gcc 9.1 Hi there! I've just published a weird c++ library targeting clang 9.0 and gcc 9.1. It implements value/type changing constexpr expressions using new c++20 features. Here's an example: ```c++ auto c = unconstexpr::meta_value{}; static_assert(++c == 1); static_assert(++c == 2); c << []{ return "hello"sv; }; static_assert(*c == "hello"sv); static_assert(std::is_same_v<decltype(*c), std::string_view>); ``` If you're a godbolt fanatic like me you can test the above [here](https://godbolt.org/z/mUZwEy) or use the project in godbolt directly by including: ```c++ #include <https://raw.githubusercontent.com/DaemonSnake/unconstexpr-cpp20/godbolt/godbolt.hpp> ``` If you like meta-programming, template, weird off-putting hacks, headaches it is just for you. You can find it here [Github link](https://github.com/DaemonSnake/unconstexpr-cpp20) Thanks for your attention! https://redd.it/e99enu @r_cpp

hello?

Words with Length N The program must accept a  space separated string S and an integer N as the input. The program must print the words from S which are of length N as the output. If no word is of length N then the program must print -1 as the output. Boundary Condition(s): 1 <= Length of S <= 1000 Example Input/Output 1: Input: Have a good day 4 Output: Have good Example Input/Output 2: Input: help the need 2 Output: -1

See this

The output is empty for this input..can anyone pls chk

The output is empty for this input..can anyone pls chk

Read something about scanf first, prior to using it

The output is empty for this input..can anyone pls chk

Scanf never returns EOF

I tried ==1 also

You can't do accidental programming with C++ or C, must learn first

The output is empty for this input..can anyone pls chk

The rest of the code is also a pice of rave.

Hi everyone! Have anyone used gRPC with serialization library other that protobuf? I would like to talk about some details, so please text me :) I saw example for Java (gRPC+Gson), but it is super language-specific

According to the C standard before C99, you need to declare i at the beginning. With C99 and C++, your original code can be compiled.

What is the error in the (for)?

declare the i first because this declaration works in the new compilers

What is the error in the (for)?

In C language i cannot be declared in the for loop

?

fichier.cpp but cant open

fichier.cpp but cant open

Don't share files but pastebin links

In C language i cannot be declared in the for loop

c99 or c11 allow to do so

I should transfer it to int array how can i do it?

just input it into array

I should transfer it to int array how can i do it?

's' to int array?

's' to int array?

Yes

all char's are integers

all char's are integers

When i try to get integers by scanf("%d"), my code doesn't work. Because there is a symbol 's'

Yes

Becouse 's' isn't in decimal number system

all char's are integers

Well yes but actually no. Ofc it is stored as a 1-byte number, but when you start work with streams a lot of changes

Well yes but actually no. Ofc it is stored as a 1-byte number, but when you start work with streams a lot of changes

They have integer representations. But still are their own data type yes

Becouse 's' isn't in decimal number system

Ok, so what should i do to transfer 's' to integer. I don't know how to implement my idea in code

Ok, so what should i do to transfer 's' to integer. I don't know how to implement my idea in code

Read as char

Read as char

Further i should work with code by integers in matrix.

And output is in integers

So, which number in decimal system 's' represents?

So, which number in decimal system 's' represents?

I got the point, thanks.

If im not wrong, c uses ascii
