Because an array of chars is a string An array of strings is an array of arrays of chars

Very true

Because an array of chars is a string An array of strings is an array of arrays of chars

Not in C++

Not in C++

array of char and std::string template ?

array of char and std::string template ?

You can have both in C++ and one is not compatible with another, so they are not same things.

Hi someone help me understand why not working correctly this source code! I hear only noise. https://forum.qt.io/topic/140076/hear-only-noises-with-qaudiooutput

what exactly does vector<int> nums(101, 0); mean in c++? could you please help?

what exactly does vector<int> nums(101, 0); mean in c++? could you please help?

Vector of size 101 with all values initialized to 0

what exactly does vector<int> nums(101, 0); mean in c++? could you please help?

it's more like, arrayname(nums), sizeofareay(101) and allarrayvalues(0)

Given an array of size which contains elements from 0 to N-1,you need to find all the elements occurring more than once in the given array and there must be a function

Given an array of size which contains elements from 0 to N-1,you need to find all the elements occurring more than once in the given array and there must be a function

A = {1,2,2,3}, compute B = { 0, 1 ,2, 1} which are frequencies of each number as that of index. Then traverse B and collect the indices havin value > 1. If the value is not restricted to N-1 or if it is huge the you can use a map<num,frequency>

// Online C compiler to run C program online #include <stdio.h> //Deepak Chaurasia main() { if (printf("hi")) { } }

Why it print in if

Output: hi

Why it print in if

Because if has to execute the expression to get a value

And print is just a regular function that returns an output too, which is the number of characters printed.

Got it , 👍

Yes, GNU debugger, IDA, Ghidra, x64/32 dbg, many more for debugging assembly level code.

Qqqoqq q

// Online C compiler to run C program online #include <stdio.h> int main() { printf("C Programm to calculate length of a integer no.\n"); int a,b,n=0 ; printf("Enter a no. "); scanf("%d ",&b); for (a =1; b <=0; a++) { b = b/10 ; n++; } printf("%d",n); return 0; }

Any problem in code

What is the purpose of a ?

While(b) { b = b/10; n++; }

Hmm ,good logic

But why this one won't give output

// Online C compiler to run C program online #include <stdio.h> int main() { printf("C Programm to calculate length of a integer no.\n"); int a,b,n=0 ; printf("Enter a no. "); scanf("%d ",&b); for (a =1; b <=0; a++) { b = b/10 ; n++; } printf("%d",n); return 0; }

It should be b>=0

Let me run

Still no output

While(b) { b = b/10; n++; }

No output using it also

While(b) { b = b/10; n++; }

This shoud work. Add \n in the print and try again

Which compiler ?

Or ide

No output using it also

Sorry, b > 0, or b != 0

Online

Wait

// Online C compiler to run C program online #include <stdio.h> int main() { printf("C Programm to calculate length of a integer no.\n"); int a,b,n=0 ; printf("Enter a no. "); scanf("%d ",&b); while(b !=0) { b = b/10 ; n++; } printf("%d",n); return 0; }

No output

If somebody with pc ,can run it

what did u enter

1/10=0.1

10

dude, you have a space in your scanf

0.1/10=0.01

dude, you have a space in your scanf

Just i saw

Space matters?

I have output now😂

my bad,its a int

Space matters?

Ofcourse. This is C, everything matters..lol

Im used to lua

Ofcourse. This is C, everything matters..lol

Btw what compiler actually doing with that space

🤔🤔

if u have a space in ur scanf,u should enter a space 2

Compiler doesnt do anything but printf expects something, pls read the documentation as I am away from C for a while now

Can i have link

Sorry I meant scanf there

I learn all from yt

I can understand but reading books is important too

However, it you are not going to make a career in C then its fine for now

Prefer C++

I was a fan of C earlier then migrated to C++. Still, we are no where close to the experts in our knowledge

As of a btech student i need to learn c as a part of syllabus

Prefer C++

Learning it also

There few very good and knowledgable peope here like our admin. I am here to learn from them

Learning it also

Agree

As of a btech student i need to learn c as a part of syllabus

That is fine. Just get it done for now. Going forward you will have oops. Either C++ or java

Then DS and Algo which will require that knowledge of C++ or Java to write the programs

Btw whice one to prefer c++ or java as priority

me personal is choose both

Its upto you. Everyone has different opnions

You should know both

Ohk thanks

Can i have link

White space (such as blanks, tabs, or newlines) in the format string match any amount of white space, including none, in the input. Everything else matches only itself. Scanning stops when an input character does not match such a format char- acter. Scanning also stops when an input conversion cannot be made (see below).

Hello world! A question regarding raylib. There is DrawTextureRec function that I use and also there are other DrawTexture functions like that. But there is no function that allows me both scale my texture AND have Rectangle source variable inside it. Is there a way to scale my current DrawTextureRec without creating new function with variables that I need?

Hii can someone help me to find out why the code is only running and not accepting input from user. (Also compiler showing 0 Errors) #include<iostream> #include<iomanip> using namespace std; class EMPLOYEE { public: int Employee_Number; string Employee_Name; float basic,DA,IT,Net_Salary; static int count; void acceptDetails() { cout<<"\nEnter Employee Number: "<<endl; cin>>Employee_Number; cout<<"\nEnter Employee Name: "<<endl; cin>>Employee_Name; cout<<"\nEnter Employee Basic Salary: "<<endl; cin>>basic; cin>>basic; count++; } void CalculateNetSalary() { DA = basic * 0.05; IT = (basic + DA) * 0.03; Net_Salary = (basic + DA) - IT; } void showDetails() { cout<<"\n--------------------------\n"; cout<<"\nEmployee Number : "<<Employee_Number; cout<<"\nEmployee Name : "<<Employee_Name; cout<<"\nEmployee Basic Salary :"<<basic; cout<<"\nEmployee Net Salary :"<<Net_Salary; cout<<"\n--------------------------\n"; count++; } }; int main() { void acceptDetails(); void CalculateNetSalary(); void showDetails(int count); return 0; }

remove void while calling function.. inside main

void acceptDetails(); => acceptDetails();

Plz can anyone

void acceptDetails(); => acceptDetails();

Ok I will try

Still not Running bro

Can anyone help me interview preparation?
