What is auto constant?

you mean auto const ?

Yes

How can i after read a CSV file, upload that automaticly on Website ? Is that possible with C ?!

#include <stdio.h> #include <stdbool.h> int count_unique(const int a[] , int length); int count_unique(const int a[] , int length){ int counter=0; for (int i = 0; i < length; i++) { bool matchFund= false; for (int j = 0; j < length; j++) { if (a[i] == a[j] && i!=j) matchFund = true; if (!matchFund) counter++; } } } int main(){ int a[]= {1,2,3,4,5,6,3,4,1,8,9,7,8}; // int length; // printf("Enter the length"); // scanf("%d",&length); int total_length= count_unique(a , 13); printf("the total Unique elements length is %d",total_length); return 0; }

Good morning to y'all. Is it possible to create a complete application using only dev cpp and then linking it to the web?? And if yes what are we gonna use to link the application to the web??

I think you need PHP to link to the web

void bubble_sort(float array[100], int size){ int i, j, t; for(i=0; i<size; i++){ for(j=0; j<size; j++){ if(array[j]>array[j+1]){ t=array[j]; array[j]=array[j+1]; array[j+1]=t; } } } for(i=0;i<size;i++){ printf("%d. %.2f\n",i+1, array[i]); } }

no

So what's the way then!

void bubble_sort(float array[100], int size){ int i, j, t; for(i=0; i<size; i++){ for(j=0; j<size; j++){ if(array[j]>array[j+1]){ t=array[j]; array[j]=array[j+1]; array[j+1]=t; } } } for(i=0;i<size;i++){ printf("%d. %.2f\n",i+1, array[i]); } }

Thus array parameter isn't exist try void func(int arr[100]){ printf("%zu\n", sizeof(arr));} Will print sizeof pointer

Hey guys Does someone has C++ open source project where I can contribute to? I have an intermediate experience of the language, just want to improve my skills

int main() { int var1; int var2; printf("Enter the width of rectangle: "); scanf("%d", &var1); printf("Enter the height of rectangle: "); scanf("%d", &var2); int perimeter = 2*(var1+var2); int area = var1 * var2; printf("Perimeter of rectangle: %d\n", perimeter); printf("Area of rectangle: %d\n", area); return 0; } This code works fine, but when I move the declaration of the perimeter and area variables to the top of the other variables, I get a bug. (I'm a beginner in C.) Help me, please

Can you post the buggy version of the code?

int main() { int var1; int var2; printf("Enter the width of rectangle: "); scanf("%d", &var1); printf("Enter the height of rectangle: "); scanf("%d", &var2); int perimeter = 2*(var1+var2); int area = var1 * var2; printf("Perimeter of rectangle: %d\n", perimeter); printf("Area of rectangle: %d\n", area); return 0; } This code works fine, but when I move the declaration of the perimeter and area variables to the top of the other variables, I get a bug.

Hello, could you please recommend a good book or udemy course to learn data structures using C++ as code base?

Are you doing declaration like this? int perimeter;

Sure! Here are a few options for books and courses that cover data structures using C++: "Data Structures and Algorithms in C++" by Adam Drozdek "Data Structures and Algorithms in C++" by Goodrich, Tamassia, and Mount "Data Structures and Algorithms with Object-Oriented Design Patterns in C++" by Bruno R. Preiss "Introduction to Algorithms" by Thomas H. Cormen, Charles E. Leiserson, Ronald L. Rivest, and Clifford Stein (This book covers data structures and algorithms using C++, but it's a more advanced text) As for courses, you could try Udemy's "Data Structures and Algorithms: Deep Dive Using Java" course. While it doesn't use C++ specifically, the principles covered in the course can be applied to C++ as well. It's also worth mentioning that data structures and algorithms are fairly language-agnostic, so while it's certainly useful to learn them using a specific language like C++, you can also learn them independently of any particular language. This can be helpful because the concepts you learn will be applicable to any language you use in the future.

If you are doing int perimeter = 2*(var1+var2); it means you are using var1 and var2 before reading values into them

Enter the width of rectangle: 4 Enter the height of rectangle: 5 Perimeter of rectangle: -26496 Area of rectangle: 0

But what do these numbers -24496 and 0 mean? Why do we get them?

Since var1 and var2 are local, their initial values are not defined and they can contain some waste

Problem Statement You love binary numbers 0 and 1. Now,You are given a binary string S of size N. Now you need to tell total how many 01 and 10 pair exist in the given string. Note - A binary string is a string which contains only 0 and 1. And you have to consider 01 or 10 as consecutive. Input Format The first line will contain T, the number of test cases. The first line of each test case contains a positive integer N. The second line of each test case contains a string S, consisting only 0 and 1. Constraints 1 <= T <= 100 1 <= N <= 1000 Output Format Print the count of pairs. Sample Input 0 4 12 101011111010 6 101011 3 100 2 10 Sample Output 0 7 4 1 1

int main() { int var1; int var2; printf("Enter the width of rectangle: "); scanf("%d", &var1); printf("Enter the height of rectangle: "); scanf("%d", &var2); int perimeter = 2*(var1+var2); int area = var1 * var2; printf("Perimeter of rectangle: %d\n", perimeter); printf("Area of rectangle: %d\n", area); return 0; } This code works fine, but when I move the declaration of the perimeter and area variables to the top of the other variables, I get a bug.

i'm testing one program, does it has a struct which it has inside one other struct, like https://pastebin.com/urwnvr42

[The following was generated by GPT chatbot, try it here https://chat.openai.com/chat I don't know if the answer is correct or not, but it helped me with some issues before, might be helpful for you too. ] It is not a bug, but a problem with the way you have declared and used your variables. In the first part of your code, you have declared var1 and var2 as local variables inside the main function. This means that these variables can only be used within the main function and cannot be accessed from outside of it. In the second part of your code, you have moved the declaration of perimeter and area to the top of the other variables. However, because these variables are declared outside of any function, they are considered global variables. This means that they can be accessed from anywhere in your code, including inside the main function. The problem with this is that when you declare a variable with the same name inside a function, it creates a new local variable with the same name that shadows the global variable. This means that the local variable takes precedence over the global variable and the global variable cannot be accessed or modified within the function. To fix this problem, you can either move the declaration of perimeter and area inside the main function, or you can use the extern keyword to explicitly tell the compiler that these variables are global and should be accessed from within the main function. For example: int main() { extern int perimeter; // Declare perimeter as global variable extern int area; // Declare area as global variable int var1; int var2; printf("Enter the width of rectangle: "); scanf("%d", &var1); printf("Enter the height of rectangle: "); scanf("%d", &var2); perimeter = 2*(var1+var2); // Access global variable area = var1 * var2; // Access global variable printf("Perimeter of rectangle: %d\n", perimeter); printf("Area of rectangle: %d\n", area); return 0; } I hope this helps. Let me know if you have any other questions.

please who know how to setup visual studio for c++

Is there anyway I can detect if the given code is a C++ or python code without getting into ML or NLP?

what's wrong with it?

A thousand line switch is an indicator of poor code design, maybe?

Why? What's the alternative? creating a ton of data structs for no apparent reason? reading a file? all of those solutions seem far more complex than what they're doing. You just inevitably end up with code like this sometimes, and in most cases, i don't think it's justified to make it more complicated than it already is. How would you write something like this, genuinely interested.

The apparent reason is you design the solution (and redesign it if the original solution is not easy to maintain) instead of simply "don't touch it, because nobody knows the edge cases it will cause". One starting point (there is no correct solutions in software design) is: starting from this point, create a bunch of mocks and tests to ensure the communication functionality is exactly as the original code and use this communications to place another approach. Properties-based development will simplify the testability and maintability of the project. I choose this approach instead of a mega-switch If you can't see what does the code do in less than 10 minutes, throw it away and start from scratch. Separation is the key here. Remember: Explicit instead of implicit is the rule of thumb. Don't expect everybody will understand what did you do. Don't assume nothing about the business model for a newcomer in the project.
