I m asking? @K11M1

you are saying that your program is not working properly, what is it doing differently that you want?

Hi guy Why my linear search program is not working properly? #include<stdio.h> int main( ) { int a[10]={ 2,4,6,8}; int num,i,position,flag=0; printf("enter the number to be searched?..."); scanf("%d",&num); for(i=0; i<5; i++) { if( a[i]==num); { printf("the number is present at position:%d",i); } } }

No need to declare a variable called "position":)

Boolean also no need.

You wrote 5, but you the size length of your array is 4.

Mane unused things and dirty code style. Don't even wanna look at it. Solve your problem yourself.

Thx Now program is working properly😊

Pls I want to do bubble sort with my class program I do get an error when I run the code

#include <iostream> #include <iomanip> #include <ctime> #include <cstdlib> using namespace std; class Rainfall { private: double rain_amount; double total_rainfall; public: void setRainfall(double rain) { rain_amount = rain; } int getRainfall() { return rain_amount; } void getTotalRainfall(double total_rain) { total_rainfall = total_rain; } int totalRain() const { return total_rainfall; } int getAverageRainfall() const { return total_rainfall / 12; } }; void intro(); int main() { intro(); return 0; } void intro() { cout<<"\t\tThis is a rainfall program in C++\n"; cout<<"\t\t--------------------------------------\n"; cout<<endl; int month = 12; string month_names[] = {"Jan", "Feb", "March", "April", "May", "June", "July", "Aug", "Sept", "Oct", "Nov", "Dec"}; int amount; int total; int lowest; int max = 200, min = 20; unsigned seed = time(0); srand(seed); Rainfall rain[month]; for(int count = 0; count < month; count++) { amount = (rand()%(max - min+1))+min; rain[count].setRainfall(amount); total += amount; rain[0].getTotalRainfall(total); } cout<<endl; cout<<"Here are the rainfall values entered by the user\n"; cout<<"Month Names\t\tRainfall Amount\n"; cout<<"--------------------------------------------------\n"; cout<<fixed<<setprecision(2); for(int count = 0; count < month; count++ ) { cout<<month_names[count]<<"\t\t\t"<<rain[count].getRainfall()<<endl; } cout<<endl; cout<<"The total Rainfall amount is: "<<rain[0].totalRain()<<endl; cout<<"The average rainfall for the months is: "<<rain[0].getAverageRainfall()<<endl; bool swap; int temp; do { swap = false; for(int count = 0; count < month-1; count++) { if(rain[count].getRainfall() > rain[count + 1].getRainfall()) { temp = rain[count].getRainfall(); rain[count].getRainfall() = rain[count + 1].getRainfall(); rain[count + 1].getRainfall() = temp; } } }while(swap); for(int count = 0; count < month; count++) { lowest = rain[0].getRainfall(); if(rain[count].getRainfall() < lowest) lowest = rain[count].getRainfall(); } cout<<endl; cout<<"The lowest rainfall amount is: "<<lowest<<endl; }

The error is at this part

do { swap = false; for(int count = 0; count < month-1; count++) { if(rain[count].getRainfall() > rain[count + 1].getRainfall()) { temp = rain[count].getRainfall(); rain[count].getRainfall() = rain[count + 1].getRainfall(); rain[count + 1].getRainfall() = temp; } } }while(swap);

Pls I need your assistance

do { swap = false; for(int count = 0; count < month-1; count++) { if(rain[count].getRainfall() > rain[count + 1].getRainfall()) { temp = rain[count].getRainfall(); rain[count].getRainfall() = rain[count + 1].getRainfall(); rain[count + 1].getRainfall() = temp; } } }while(swap);

Please, first learn how to read the error. ))) I'm sure you aren't blind. Modern compilers should write everything clearly.

I don't know how to fix that's why I said u guys should assist me

for swapping things cannot you just use std::swap?

just curious if you were to trying to write it without it

I wanted to try if I could swap values contained in classes

with normal arrays, the above works

Cppreference

today still no std::htonll

You have c++23 bswap and std::endian, or you implement it with shifts and pray that a non Microsoft compiler will optimize it (they generally do, ms ones don't)

that’s why rust performs far better in terms of standard library

Sorry, but from the inside rust standard lib manages to be more of an horror story than stdlibc++

And even worse than libphobos which was also quite traumatic

The most problematic parts of C++ are relics: the iostream, std::allocator, locale facets, and std::unordered_map

The rest delivers what it promises (except whatever passes for an implementation of make_heap on libstdc++ but really, did you ever use make_heap at work?)

Hi guys, I’m studying MSc International Management but I’ve always been interested in coding. So some days ago I started with C, I hope to find useful resources and nice people here :)

I still remember when I was confused when reading the following for the first time 🤣 : In object-oriented and functional programming, an immutable object (unchangeable object) is an object whose state cannot be modified after it is created. This is in contrast to a mutable object (changeable object), which can be modified after it is created.

What kind of horror story?

#include <iostream> using namespace std; int main() { int a[3]; a[0]=1; a[1]=2; a[2]=3; int x[3]; x=a; return 0; } Why error: invalid array assignment?

#include <iostream> using namespace std; int main() { int a[3]; a[0]=1; a[1]=2; a[2]=3; int x[3]; x=a; return 0; } Why error: invalid array assignment?

why not use a pointer? int *x; x=a;

#include <iostream> using namespace std; int main() { int a[3]; a[0]=1; a[1]=2; a[2]=3; int x[3]; x=a; return 0; } Why error: invalid array assignment?

an array name is not a valid lvalue, cannot be assigned to

an array name is not a valid lvalue, cannot be assigned to

Can't understand lvalve??

You mean 'a' stores address of the array. And we can't store an array's address to x having type-int!!

Can't understand lvalve??

sorry typo... should be lvalue, left value

When we have to use size function of vector. We do vector_name.size() Then why, we don't do same for iterator? Example: vector_name.iterator is wrong. But, vector<int> :: iterator it = v.begin; is right???

Please clear my confusion between fullstop and double colon . and ::

What kind of horror story?

code that works "in theory" but doesn't take into account IEEE754 properties, code that uses generic but very suboptimal algorithms instead of using type introspection and other things like that

Method and namespace ?

#include <iostream> using namespace std; int main() { int a[3]; a[0]=1; a[1]=2; a[2]=3; int x[3]; x=a; return 0; } Why error: invalid array assignment?

The statement "x=a" is assigning the memory address of a to x which doesn't make sense, hence leading to compilation issues because two different arrays are referencing the same address in memory.

Silly question, why most people hate C++ STL ?

Hi, Is “Learn C the hard way” valid for a beginner? (after I learned the basics and pointers)

much more complicated than it seems, but lacks many features (or added in very recent standards)

C language will give more then you can get from other high level languages. After C language you'll understand that Java, Python or even C# are garbage. Even if they have a lot of sugar syntax. C language will allow you to learn much more and more better way how it's really works. Other languages are hiding the most tasty parts of a language, that's why Java or Python programmers can't do real programming. They can only use a language like a Lego game. Java was written in C language, Python was also written in C language. But you can't make your own powerful language using Python or even Java. So now I hope you understand what C language is. It's a power))

Lmao

I've not seen such a narrow-minded opinion in years

I hope you grow up sometime

Maybe you can give a more wide explanation:)

The purpose of programming is to get things done. Not to sink in "tasty parts of a language". A programming language is not a goal or an absolute, it's just a tool.

But I would argue that the other languages have created an easy run through and have built many libraries and frameworks which c real kinda hasn't eg I tried to seek a library or framework that would creat a window graphics but really search for a long while and just let it go

I hope you grow up sometime

Please telling how am sure his trying it good to enlighten people you know

So, your statements that "Java or Python programmers can't do real programming" - just silly.

There is no "real" or "fake" programming. The world is not black and white. Any statements like "They can't do real programming, but we can" are so childish

Maybe you should search who wrote all libraries for you to use them in Python or Java.)) I think you never even worked in a big companies. Just making HTML sites

> Maybe you should search who wrote all libraries for you to use them in Python or Java So, not all libraries available to Python are written in Python - so what? :)

So, anyways, @AndelieYoujin, I'd suggest you not to embarrass yourself and grow up already
