Guys, what is this thing called, its so weird: [](args...) { /* body */ }

looks like lambda

closure is what its called

I see that this passed as argument, how is it possible too 😂

WTF are you doing?

I have a book thanks. It's not like I didn't knew the rules. I don't know how but I made a stupid mistake and my mind couldn't catch it.

fun(){ int n; scanf("%d", &n); for(int i=0; i<10^6; i++) printf("hello"); } what is rate of growth and time complexity for above block of code...?

Constant

u mean O(1) or O(10^6) ?

They are same

yeah they both are constant...so bot the answer is correct?

No, constant complexity is symbolized only by O(1)

unsigned int gcd (unsigned int a, unsigned int b) { if (a == 0 && b == 0) b = 1; else if (b == 0) b = a; else if (a != 0) while (a != b) if (a < b) b -= a; else a -= b; return b; }

Is learning c worth?

No

Why

You should not be writing any new code in C

Then?

Legacy codebases can benefit from some knowledge of C

using namespace std; #include <iostream> #include <math.h> int funct_bmi(int w, float h) { return w / (h * h); } class BMIweight { public: int weight; void set_weight(int w) { weight = w; } void put_weight() { cout << "Weight= " << weight << endl; } }; class BMIheight { public: float height; void get_height(float h) { height = h; } void put_height() { cout << "Height= " << height << endl; } }; class BMI : public BMIheight, public BMIweight { public: void put_BMI() { int BMI; BMI = funct_bmi(weight, height); cout << "Your BMI is: " << BMI << endl; } }; int main() { BMI a; cout << "Put weight(in kgs): "; cin >> a.weight; cout << "\nPut height(in meters): "; cin >> a.height; cout << "\n"; a.put_weight(); a.put_height(); a.put_BMI(); if (BMI > 25) { cout << "You are fat"; } else if (BMI < 15) { cout << "You are skinny af"; } else { cout << "You are fit"; } return 0; }

Found this question online while practicing, tried coding and still finding challenges. Anyone to help, here's the Scenario... ZIT primary School is designing a student information system to keep records of their pupils. The information they wish to keep about each pupil  Pupil ID  First name  Surname  Age  Grade  Guardian phone number. The expected users of the system will include the head teacher, deputy head teacher and two teachers. The privileges of editing, adding and deleting records will only be handled by the head teacher and the deputy head teacher. Teachers will only be allowed to search or view records of students. Your group has been hired to design a demo program that uses arrays, files, loops and selection structures in C++ to meet the needs of ZIT primary school. For testing purposes, assume that there are only two Grades (1 & 2) and each grade has only 5 pupils. Your program must meet the following additional requirements a) Allow only authorised users (i.e whose credentials are stored in the text file) to logon b) After the user has logged on, the program should display the menu below 1. Add New Pupil 2. Delete Pupil 3. Search for Pupil 4. Edit Pupil Record 5. Display All Pupils by Grade 6. Exit c) All records should persist between program executions (i.e information must be save to the file when the user exits and reloaded from the file when the program is executed)

I have included in both but I get an error of multiple declaration

ur homework?)

how do i read only the average

can someone help me
