How to combine struct to a function in c??

I mean this is possible, but very unlikely what you need. What exactly are you trying to do?

#include <stdio.h> typedef struct { int number,age; char name[50],info[100]; } follow; void create(){ FILE *p; if((p= fopen("Myfile.txt","w")==NULL));{ puts("File could not be found!"); } else{ follow records{1, "", "",2}; for (int i = 1; i <= 100; i++) { fwrite(&records, sizeof(follow), 1, p); } fclose(p); } } int main(){ create(); }

Check brackets in your first “if” statement in ‘create’ function. I think you should close bracket after ‘p=fopen(…)’

Only that?

I don’t know that’s only what I noticed at first reading:) Sorry for bad English

Anyone join the project. A game from real scratch.

Firstly, remove the HTML entities with some online convertor...

I got this from my group

Can someone tell me how I should proceed after completing DSA foundations with popular problems? I give CC challenges. I've decided to at least continue and do some problems on Hackerrank (maybe until I get a 5*). What should I do in par with it, to enhance my problem solving skills? Should I start solving on Codeforces then or GFG/ Leetcode? PS : I'm in 2nd year

Hi guys, I need some info. What tf is wrong with SIGUSR1? I'm using sigaction and kill sending SIGUSR1, the process that should receive the signal just ignore it, just SIGUSR1, I changed SIGUSR1 with SIGPIPE, just for debugging, and it's work fine. Can someone explain me wtf is going on? I'm losing hope. TY

any one who is good at c++

Do real projects.

exercism.io has some cool challenges, pretty difficult but then again I've only been at this for a few weeks

Because I don't think I can pull off hard questions at first. So lemme get a good hang of it

try hacker rank

I am not a programmer but my job involves writing python scripts and interacting with different APIs, which I am good at. But I suck at solving hackerrank type of questions. I've tried going through some data structures and algorithms courses. Any tips on what should I be learning if the end goal is to be able to solve those hackerrank / leetcode challenges?

for leetcode just open user solution.

interracting with APIs isnt hard. Problem solving is the part where you'll have to think a lot.. just keep on practicing, see solved solutions for the particular problem and learn how they implemented the code etc..

That's what I do right now but what beats me down is I am mostly not able to solve them by myself.

Why does this code segfault when I use new? https://pastebin.com/L9YsbwV4

why is it recursive?

oh I see. So how would I go about allocating memory when a class is constructed

The class itself

Why else would I see foo_class *foo_obj = new foo_class()

// C++ implementation of the approach #include <bits/stdc++.h> using namespace std; // Function to return the maximum profit // that can be made after buying and // selling the given stocks int maxProfit(int price[], int start, int end) { // If the stocks can't be bought if (end <= start) return 0; // Initialise the profit int profit = 0; // The day at which the stock // must be bought for (int i = start; i < end; i++) { // The day at which the // stock must be sold for (int j = i + 1; j <= end; j++) { // If byuing the stock at ith day and // selling it at jth day is profitable if (price[j] > price[i]) { // Update the current profit int curr_profit = price[j] - price[i] + maxProfit(price, start, i - 1) + maxProfit(price, j + 1, end); // Update the maximum profit so far profit = max(profit, curr_profit); } } } return profit; } // Driver code int main() { int price[] = { 100, 180, 260, 310, 40, 535, 695 }; int n = sizeof(price) / sizeof(price[0]); cout << maxProfit(price, 0, n - 1); return 0; can anybody tell me the thought process to write a code like this on my own

Its a simple recursion.

Can we place two or more catch blocks together to catch and handle multiple types of exceptions thrown by a try block.

And does c++ compiler check if any error is caught or not

Is the hacking.cpp website good or bad for learning c ++?
