Consider the following piece of C++ Code: #include <iostream> #include <cmath> using namespace std; int main() { cout.precision(1000000000); float a,b,c; a = 1; b = -1; c = pow(2, -50); cout << "a = " << a << endl; cout << "b = " << b << endl; cout << "c = " << c ..

I just wanna make sure whether this code is good or it needs improvement. What do you all think? #include <iostream> using namespace std; u = (a%10+b%10+c%10+d%10+e%10+f%10); t = (a / 10 % 10 + b / 10 %10 + c / 10 % 10 + d / 10 %10 + e / 10 % ..

Given an array we have to take average of an array and then take floor of that average and that value should be less than k. Link of this question:- https://www.hackerearth.com/practice/data-structures/arrays/1-d/practice-problems/algorithm/minimum-additions-0142ac80/ MY CODE:- #include "bits/stdc++.h" using namespace std; int main() { int t; cin>>t; while(t–){ int n,k; cin>>n>>k; int arr[n]; int s = 0; for(int ..

How do you use a while loop only to add multiple values with a given point when to exit the loop and display the tallied amounts. Note the following example. Test your program by entering 7 for the number of items and the following values for the calories: 7 – 120 60 150 600 1200 ..

I have a very simple calculation where I calculate the distance between each individual cell to center in a 2D space. I know that the O(n) solution is redundant and I derived the formula for O(1) solution. But what I am trying to understand is: Why do these two trivial calculations give me two different ..

#include <iostream> #include <string> using namespace std; namespace ComplexNumberNamespace { typedef struct _Data { double real; double imag; }Data; class ComplexNumber { private: Data data{}; public: ComplexNumber(); ComplexNumber(float real, float imag); ComplexNumber(ComplexNumber&); string to_string(); void operator = (ComplexNumber&); ComplexNumber operator + (ComplexNumber& rhs); }; string ComplexNumber::to_string() { std::string str; str = std::to_string(data.real); str.append(" + i ..

i am a novice to C++ , I was trying to write this program for adding two very large numbers using strings but the program is not working correctly and I can’t get what’s wrong with it , please help me with this. #include<iostream> #include<stack> #include<string> using namespace std; int main() { stack <char> a1; ..
