When we use the (if -switch) ? What the difference between words ?

quiz question?

$ diff if switch

wtf is difference between words

switch can only test for equality whereas if can test for any Boolean expression. switch tests the same expression against constant values while if-else-if ladder can use different expression involving unrelated variables. switch expression must only evaluate to byte, short, int, char, String or an enum. if doesn’t have such limitations. A switch statement will run much faster than the equivalent program written using the if-else-if ladder

Why do you learn C and not C++?

Interested in Malware Analysis/Exploit Development Plus I would like to start from low-level in order to understand better programming principles, so I can learn easily languages useful for my future job (Python —>business/finance)

is really python used in finance? i thought that finance is more c++ than python

What is the best way to learn the data structures and algorithms

A book first on that

Which one

Data structures and algorithms Seems pretty boring so how to make it interesting ?

Do you have the book... pdf ?

any details about these? GitHub issues or whatever

People that submitted that got... erm religious backlash on reddit mostly

Okay but my question still is unsolved ahahah Is “Learn C the hard way” valid for a beginner? (after I learned the basics and pointers)

I think that c programming will be the most suitable way to choose as beginner

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

Can't understand lvalve??

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 :)

How Write a pseudocode algorithm that converts infix expressions to equivalent prefix expressions ????

Who told you that ?

Have you got commercial experience ? 😅

I found many articles saying C++ STL is bad

Can someone help me to understand how to solve this problem? When I run my code on the terminal it shows me this message: zsh: segmentation fault Actually, problem is that I'm trying to get a string for *fname which is in the structure by scanf("%s", myarray->fname); but doesn't work properly

#include<stdio.h> #include<stdlib.h> #include<string.h> #define LIMIT 50 typedef struct{ char * fname; char * lname; int * show; }record_t; record_t * createArray(int maxsize); record_t * insert(record_t *myarray, int *maxsize, int *currentsize); int main(void) { int maxsize; printf("Enter a size for the dynamic array: "); scanf("%d", &maxsize); record_t *myarray = createArray(maxsize); int currentsize = 0; int option = -1; myarray = insert(myarray, &maxsize, &currentsize); free(myarray); myarray = NULL; return 0; } record_t * createArray(int maxsize) { record_t * arr = (record_t *) malloc(maxsize * sizeof(record_t)); if(arr == NULL) { printf("malloc error in createArray...program exiting\n"); exit(1); } return arr; } record_t * insert(record_t *myarray, int *maxsize, int *currentsize) { scanf("%s", myarray->fname); return myarray; }

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))

C is many times better than Java. Java does not compile to a final native code. It uses JIT just in time compiler. Python is like Qbasis it does not compile. So both Java and Python are very weak. C is very very good. It compiles to native code and teachs real programming.

And why do you think despite being "weak" (according to you), java still being used widely in industry? Maybe to maintain the legacy codebase?

Widely?? You can't run a factory with java, you can't run your BMW with java. In mobile games only? Okay. That's fine. You can't even imagine how widely C is used.

I believe what they meant by weak is due to GC, it has a runtime cost compared to something like C or Cpp

All languages are good, it depends on what you wanna get from it.

I recommend you to forget about Python. Use it only at home for yourself. All libraries for Python are written by crazy hackers in C language. If you wanna use a language just for fun, go on with Python. It's okay a good language to destroy the understanding of programming:))

Keras is written in Python, scikit-learn is also written in Python along with many ML implementations.(So, python is not a bad language as it has its own purpose).(Also, efficiency of program depends on the programmer and not the programming language itself. Eg: Ryujinx(C#, garbage collected) vs Yuzu(C++))

Haha, garbage collector. Now I understand. Go on with Python and don't ask stupid question.))

So it pointing to random address because it's undefined

For arduino it’s better C or C++?

Neither one is just “better”, it all depends on what code you write

Can u solve a que for me

Haha, garbage collector. Now I understand. Go on with Python and don't ask stupid question.))
