but it does in this case? this is completely valid: int foo(int abc); int foo(int xyz) { return xyz; }

What I need to change now?

oh, yes :') i phrased it mostly as a "better practice" thing, the compiler will interpret the functions with the same name differently if their parameter types/parameter count is different

fix the compile errors? Again, your compiler will tell you https://godbolt.org/z/ra9o1fanW

YouTube tutorials for c++ ?

This is telegram group, if you wants youtube tutorials you should go to youtube.com and write "c++ tutorial"

#include <iostream> using namespace std; int findLargest(vector<int>&); int main() { vector<int>hebat; int Size; int Value; int Largest; cout<<"How many integers would you like to enter?"; cin>>Size; for (int i=0; i<size; i++) { cout<<"Enter your Number "<<i+1<<":"; cin>>Value; hebat.push_back(value); } Largest = findLargest(hebat); cout<<"The Largest Value is :"<<Largest; return 0; } int findLargest(vector<int>& temp) { int max=temp[0]; for(int j=i; j<temp.Size();j++) { if(temp[j]>max) max=temp[j]; } return max; }

Do you know it?

no one does since the description is not complete

Write a function such that the hundredth array A (of type double) takes a number v (of type double) and an array of hundredth B (again of type double) and performs the multiplication operation on the number v × A = B. Show how in main you can use this function to multiply the vector X by 5 and put it in the vector Y. The program must include a complete definition of the function, Define the variables X, Y and use the function by main

What about it?

about this? this sounds like some assigment from some school

No It isn't. Is it true?

The first time i run the program is right but if in the same program i call that function the strDef value is ab�_salida.txt why is � in there?

UB?

Unknown Behavior

Undefined

but code seems right?

int abrirFicheros(FILE** fichero, FILE** salida) { char nombre[100]; int est = 0; char sal[100]; strcpy(nombre, ""); // ---------------PEDIMOS FICHERO LECTURA------------------------------------------------------------- printf("FICHERO: "); scanf("%s", nombre); char strDef[100], dot = '.'; strcpy(strDef, ""); int i = 0, j = 0, foundChar = 0, length = strlen(nombre); while(i < length) { if (nombre[i] != dot && foundChar == 0) { j = j +1; } else { foundChar = 1; } i = i + 1; } strncpy(strDef, nombre, j); printf("\nNOMBRE FICHERO SALIDA: %s\n", strDef); //strcpy(strDef, "b_Sa.txt"/*strcat(strDef, "_salida.txt")*/); strcat(strDef, "_salida.txt"); printf("\nNOMBRE FICHERO SALIDA: %s\n", strDef); //strcpy(sal, strDef);```Someone knows how to correctly create the string ```strDef The idea is to have the same string 'nombre' but only the left until the dot is found and the concatenate '_salida.txt'

How can i do that?

Hello guys, I only understand this source code superficially: bool digit_seen[10] = {false} int long n; printf("Enter a number: "); scanf("%ld", &n); while (n > 0) { digit = n % 10; if (digit_seen[digit]) break; digit_seen[digit] = true; n /= 10; } if (n > 0) printf("Repeated digit! \n"); else printf("No repeated digit\n"); I understand most of them; however, I couldn't comprehend the "if (digit_seen[digit])" properly and was only able to get the gist of it. Could anyone explain it to me? Thanks a lot!

It is checking particular digit status in digit_seen array if it's true then it breaks.

Hey everyone, Anybody who speak the language of regex 😅 I need help Need to make a regex pattern to replace the value after = Example Variable=/path/to/value args ^Variable=(.*?) 😅 The max that i can understand Basically i need to replace the "/path/to/value" only "Variable" is constant "args" need to be as it is

https://www.indeed.com/career/c%2B%2B-developer/career-advice You can see cpp developer skills for hiring in a job on usa. And learn this skills. Its my way to learn.

That is a rather vague baseline. Take multithreading: basic multithreading tasks reduce to making a multithreaded process in several single threaded processes (mutual exclusion, parallel computation, map-reduce, state-free programming), but alternatives like lock free or wait free programming do exist and are not well taught. Likewise, good multithreaded code requires a quite intimate knowledge of both the kernel and the hardware In summary, yeah focusing on that will get you hired, but may not make you an any decent programmer: it is more complicated than that
