please read the rules * If you encounter a problem, while using dev C++ or turbo C/C++, you will not be helped, use another more modern IDE.

I can use any IDE? Plz suggests

Talula

I can use any IDE? Plz suggests

IDE? Visual Studio.

You could also use C++ Builder

Talula

There are other IDE, if I say the name, people will curse me for life.

I can use any IDE? Plz suggests

Visual Studio, Eclipse, Clion are probably the most common Otherwise go for VS Code and gcc which works on every platform

V01D

can anyone help me please, why do I get constantly 8 if I want to get size of an element in the array? and why do i get 48 as the size of an array? how I think, i should get the size of an element as max element size of the whole array, in my case, size of apricotadds, but its size isnt 8

sizeof returns the size of a variable in BYTES.

V01D

And what's the size of a char in bytes? 8!

V01D

So sizeof(fruits) = the sizeof a char * the elements in the array, aka 8 * 6

Vlad

And what's the size of a char in bytes? 8!

You meant char*?

.....

Assignment help

V01D

You meant char*?

Nah, just a char data type. I only spoke about it since his strings didn't exceed 8 bytes.

Vlad

Btw initing array of char* with const char* is totally wrong

Vlad

Nah, just a char data type. I only spoke about it since his strings didn't exceed 8 bytes.

Why tho? It's an array of pointers

Vlad

Size of the stuff that those pointers point to doesn't matter for the sizeof

vinícius*

Size of the stuff that those pointers point to doesn't matter for the sizeof

Yeah.. it's better not to teach him wrong stuff

vinícius*

A single char is traditionally a single byte, not 8

V01D

A single char is traditionally a single byte, not 8

Pretty sure a char is 8...

vinícius*

Nope..

Vlad

A single char is traditionally a single byte, not 8

char shall always be one byte in C

vinícius*

8 bits, not 8 bytes

V01D

Yeah.. it's better not to teach him wrong stuff

Well shoot. Everytime I come here I answer it all wrong, how tf even.

.....

Size of the stuff that those pointers point to doesn't matter for the sizeof

That's ok bro some time it's happen

Vlad

That's ok bro some time it's happen

i have a rectangle with a length of 700 inside, i have a fixed region of 100, 500, and variable region in the middle (100, 100, 500) when i click on say 210, which is inside the 500 region, how do i calculate the required variable region width such that it is always the same regardless of where in the region i am clicking in the context of a resizable rectangle (hence the variable region) as i am currently calculating it as width = clickedLocation width -= 500 as i just cant seem to figure this out ;-; i know that i can eliminate the offset by doing location - regionLength - widthLeft // location - 100 - 100 however this does not fix it entirely old regionLength = [724.0] location = [975.58594] regionLength = [724.0] widthLeft = [100.0] new regionLength = [151.58594] old regionLength = [151.0] location = [973.47656] regionLength = [151.0] widthLeft = [100.0] new regionLength = [722.47656] as it flickers and is partially correct in width but at the same time incorrect in width and doing float locationFixed = location - regionLength - widthLeft regionLength = location - locationFixed; just screws it up, as does regionLength = regionLength - locationFixed;

Why strrev function in string.h is not available now

Igor🇺🇦

Why strrev function in string.h is not available now

It wasn't a standard C function. And it's dangerous because it can be used for buffer overruns

Igor🇺🇦

In C++ you should use https://en.cppreference.com/w/cpp/algorithm/reverse

Aniket

But was included previously

brahim

install wmsAuthSign ?hash= for php player

brahim

What insatall method

Gulshan

man

vinícius*

But was included previously

strrev is not part of any C standard. If you used it before, you used it as an extension

vinícius*

Just use a replacement... it's not hard to reverse a string

Gulshan

Igor🇺🇦

But was included previously

It was, now it isn't. You can write your own. gets that even was a part of standard was removed too. It happens

Aniket

Yes by including string.h

Gulshan

can Anyone tell me that what should I use instead of "make ./raymond"

Gulshan

I know it is clearly written but I can't able to fire that command without encountering any error

I want to participate in open source project then plz guid me how i will do that

Gulshan

should I make a new cmakelist.txt file or I should opt for the default file got from the plog repo ?

Gulshan

I want to participate in open source project then plz guid me how i will do that

get a github account and contribute to other's code, by doing some fixes in their code, or anything else which is required in their respective repo

Igor🇺🇦

Go to github or bitbucket and find something that interests you. Try to fix bugs there and to submit patches

double control=2,no1,no2; while( control==scanf("%lf %lf",no1,no2){ if(control==2){ ... } else break; }

I am controlling if user entered two double number or not ,if he did not enter double (enter smth else) i want to exit from loop,but it is not working,there is an infinite loop,how to fix it

Shaurya

double control=2,no1,no2; while( control==scanf("%lf %lf",no1,no2){ if(control==2){ ... } else break; }

you can not compare double value with integer value

Shaurya

I am controlling if user entered two double number or not ,if he did not enter double (enter smth else) i want to exit from loop,but it is not working,there is an infinite loop,how to fix it

double n1,n2; int cnt = 2; while(cnt == scanf("%lf%lf",&n1,&n2)){ // expression }

vinícius*

double n1,n2; int cnt = 2; while(cnt == scanf("%lf%lf",&n1,&n2)){ // expression }

What kind of input do you wanna block exactly?

vinícius*

If the user types in integers, C is just gonna cast it to double

vinícius*

Your current logic works when avoiding chars

vinícius*

But.. is that what you want?

Shaurya

If the user types in integers, C is just gonna cast it to double

In C/C++ we use variable after declaring its type So, If we declare double then sure integer will consider as double from the input

Shaurya

In you want to handle integer and double separately then #include<bits/stdc++.h> using namespace std; int main(){ string num1, num2; double n1, n2; int cnt,f; do{ cnt = 2; cin>>num1 >> num2; f = 0; for(auto n : num1){ if(n == '.') { f++; continue; } else if(n <'0' && n >'9'){ cnt--; break; } } if(f != 1) break; for(auto n : num2){ if(n == '.') { f++; continue; } else if(n <'0' && n >'9'){ cnt--; break; } } if(f != 2) break; if(cnt == 2){ n1 = stod(num1); n2 = stod(num2); } }while(cnt == 2); return 0; }
