How to get good at competitive programming

First thing give urself time! Take 6 months to one year! Be strong in fundemantals! After that get ur self comfartable with using libraries and macros! Register in online comletative programming platforms like hackerearth.com, this group! Discuss with peers! Practise practise!

plzz help me to find my mistake there

#include<iostream> using namespace std; int main() { int num1,num2; cout<<"enter 1st number"<<"enter 2nd number"; cin>>num1;num2; cout<<"this is difference of num1 and sum2" <<(num1+num2) ; return 0; }

cin >>num1>>num2;

Wow ur game developer?

How to get good at competitive programming

Competitive programming is useless in my opinion. In real world you dont see a situation often where you have to devise an algorithm within an hour or faster than others. What is more important is to learn Algorithms like Graph Algorithms, String Algorithms, Greedy and Dynamic Programming, NP Completeness and so on. This would help you in competitive programming but.more importantly it will give you a toolset to tackle real life problems. The latter is more important than the former. The former is just a side effect which comes with practice. Competitive programming at best is used to hire freshers in this extremely competitive market. But once you are in a job and gain 3 years of experience you would lose all urge to excel in that.

There is this set of 291 coding questions from must do interview questions from geeks ...I'm solving them...am I going the right way

It wont hurt. As a fresher it might even help you land a job. But dont make excelling at competitive programming an ambition. If anything it encourages bad coding practices which must be avoided at all costs in the professional world. Instead of blindly solving those questions, try to understand how they must be solved. That would prove more useful in the longer run.

Yes...but if I Join mtech...I'll have to compete with btech guys who have been coding from their first year..how do I compete

there is an error use binary operator

here i am getting output of a%b WHY ?

all output is ok except that %

https://pastebin.com/PKUHqU1A

not getting 0

Put a%b into bracket, then try

then what

a/b gives 0

but a%b gives nothing

is output is 0

a%b is 9

Not 0 output must be 9

https://pastebin.com/PKUHqU1A

hello world 29 -11 180 0 9 9 10 10 9

Please count your operations and answers and compare them if equal no such as problem that you suggested, if smth wrong in your code compiler gives you error

Overloaded operator << didn't work

Overloaded operator << didn't work

Because you have made it a member function. Make it a friend function instead.

I tried it but it's not working

Show us the code where you have made it a friend function. Post it on pastebin.com again

It works but why it is not works as a member function

Ok

Is it possible to return a struct from a function in C? I tried, can you tell me what is wrong?

Learn programming (from good sources) and learn good coding practices. Learn to use tools like the compiler, debugger, static analysis, run time analysis, unit testing frameworks and so on. Solve those questions in a proper way following coding guidelines. You would solve them slower but framing a solution faster than others is not the point. Writing code in a secure, adaptive and readable manner is more important. If you do all of the above or atleast work on it, take it from me that you would be more employable than a Summa cum Laude or Magna cum Laude graduates from many of those Indian colleges. And if you are talking about a BTech program in India, let me assure you that those colleges (except for a few) don't churn out the best programmers around. They still use Yashwant Kanitkar, Balaguruswamy, Herbert Schildt, Ivor Horton and Sumit Arora textbooks which are nothing but horribly written programming textbooks. These graduates will have a lot of unlearning to do to be good programmers.

A{p} can match a initializer_list constructor. A a(p) cannot. struct P { int p = 0; }; struct A { int a = 0; A(P p) { cout << "1"; } A(initializer_list<P> l) { cout << "2"; } }; int main() { P p; A a(p); A{p}; } For example, this code will output "12".

#include <iostream> using namespace std; #define MKSTR ( x ) #x int main (){ cout << MKSTR (HELLO C++) << endl; return 0; }

#include <iostream> using namespace std; #define MKSTR ( x ) #x int main (){ cout << MKSTR (HELLO C++) << endl; return 0; }
