HackerRank Overload Operators solution in c++ programming YASH PAL, 31 July 202422 August 2024 In this HackerRank Overload Operators problem in the c++ programming language You need to overload operators + and << for the Complex class. HackerRank Overload Operators problem solution in c++ programming. //Operator Overloading #include<iostream> using namespace std; class Complex { public: int a,b; void input(string s) { int v1=0; int i=0; while(s[i]!='+') { v1=v1*10+s[i]-'0'; i++; } while(s[i]==' ' || s[i]=='+'||s[i]=='i') { i++; } int v2=0; while(i<s.length()) { v2=v2*10+s[i]-'0'; i++; } a=v1; b=v2; } }; //Overload operators + and << for the class complex //+ should add two complex numbers as (a+ib) + (c+id) = (a+c) + i(b+d) //<< should print a complex number in the format "a+ib" ostream& operator<<(ostream& os, const Complex& c) { return os << c.a << (c.b > 0 ? '+' : '-') << 'i' << c.b; } Complex operator+(const Complex& a, const Complex& b) { return { a.a + b.a, a.b + b.b }; } int main() { Complex x,y; string s1,s2; cin>>s1; cin>>s2; x.input(s1); y.input(s2); Complex z=x+y; cout<<z<<endl; } Second solution //Operator Overloading #include<iostream> using namespace std; class Complex { public: int a,b; void input(string s) { int v1=0; int i=0; while(s[i]!='+') { v1=v1*10+s[i]-'0'; i++; } while(s[i]==' ' || s[i]=='+'||s[i]=='i') { i++; } int v2=0; while(i<s.length()) { v2=v2*10+s[i]-'0'; i++; } a=v1; b=v2; } }; //<< should print a complex number in the format "a+ib" //Overload operators + and << for the class complex //+ should add two complex numbers as (a+ib) + (c+id) = (a+c) + i(b+d) Complex operator +(const Complex &x, const Complex &y) { Complex z; z.a = x.a + y.a; z.b = x.b + y.b; return z; } //<< should print a complex number in the format "a+ib" std::ostream &operator <<(std::ostream& os, const Complex &z) { os << z.a << "+i" << z.b; return os; } int main() { Complex x,y; string s1,s2; cin>>s1; cin>>s2; x.input(s1); y.input(s2); Complex z=x+y; cout<<z<<endl; } coding problems cpp hackerrank solutions
