Which software is best than VS Code...?

Can doubly linked list implemented using single pointer ?

I changed it to work in VS: #define _CRT_SECURE_NO_WARNINGS #include<stdio.h> #include<stdlib.h> #include<string.h> typedef struct { int* piData; char* pcName; } Info; int main() { Info MyInfo; MyInfo.piData = (int*)malloc(sizeof(int)); if ((MyInfo.piData) == NULL) { printf("FAILED TO ALLOCATE MEMORY\n"); return 0; } *MyInfo.piData; scanf("%d", MyInfo.piData); printf("MyInfo.piData = %d\n", *MyInfo.piData); MyInfo.pcName = (char*)malloc(sizeof(char) * (*MyInfo.piData + 1)); if ((MyInfo.pcName) == NULL) { printf("FAILED TO ALLOCATE MEMORY\n"); return 0; } strncpy(MyInfo.pcName, "programmer", (*MyInfo.piData)); MyInfo.pcName[*MyInfo.piData] = 0; printf("MyInfo.pcName = %s\n", MyInfo.pcName); system("Pause"); }

Anyone using atom ide ? plz reply need help

Yeah

Thanks

👍🏻👍🏻

vector<vector<int>> getAdys(vector<vector<int>> cities, int n){ vector<vector<int>> v(n,vector<int>()); for (int i=0; i<cities.size();i++){ v[cities[i][0]].push_back(cities[i][1]); v[cities[i][1]].push_back(cities[i][0]); } return v; }

I wanted empty inner arrays

yes, i filled them manually

Try to Google

#include<stdio.h> int leftrotate(int a[],int n){ int temp=a[0],i; for(i=0;i<n;i++){ a[i-1]=a[i]; } a[n-1]=temp; } int leftrot(int a[],int n,int d){ int i; for(i=0;i<d;i++) leftrotate(a,n); } int mian() { int a[5]={1,2,3,4,5},d=2; leftrot(a,5,d); return 0; }

What is int mian() ?

You have no int main() function

Hey .Write a program to input Marks of 50 students and display marks of top 3 students. What will be the condition for second and 3rd student . while solving without using array

That's stupid, you SHOULD sort an array for a problem like that! Otherwise it would look similar to this: https://nekobin.com/mobifaloka

Anyone can help me out?

What's the benefit of writing a simple for loop in C like this long j; for (j = 0; j < N; j++) { // some computation } Instead of for (long j = 0; j < N; j++) { // some computation }

Why, my professor is doing it and he's been coding C since 30 years

You better figure it out yourself

Since 30 years or for 30 years?

for this long j; for (j = 0; j < N; j++) { // some computation } // some computation with j is possible while this for (long j = 0; j < N; j++) { // some computation } // some computation with j yields an error // j is block scoped in the loop

Thanks for you answer! It's strange because there is no other computation in the procedure

If you want to preserve the value of j for further use, it's okay Usually best practices with loops local variables are to be scoped inside the loop as much as possible, because it will make your function more clear and reduces the stack memory of the function (because the loop variables ends its scope once all the loops finished) so you won't get any useless extra space for your program

Hello, must I define a default constructor for a class if for some reason it I create a constructor with parameters and would use it for just special cases? Like for the default constructor, I create a prototype in class without ever defining it?

Thanks for the answer

Well In my opinion You would use default constructor in case you want some default state of your object (class fields), and another constructor to set a way of how your initialized object works
