Write a c plus plus program to use plus operator to display the sum of 2 numbers and concatenation of two strings by using operator overloading?
There is no need to overload the plus operator to achieve this. It is already overloaded with this functionality. #include<iostream> #include<string> int main() { int x=40; int y=2; int z=x+y; std::cout<<x<<" + "<<y<<" = "<<z<<std::endl; std::string s1="Hello "; std::string s2="world!"; std::string s3=s1+s2; std::cout<<"""<<s1.c_str()<<"" + ""<<s2.c_str()<<"" = ""<<s3.c_str()<<"""<<std::endl; return(0); }
How do you write a c plus plus program to print aaaa aaab aabb abbb bbbb?
#include<iostream> #include<string> #include<algorithm> bool compare_no_case (const char a, const char b) { return tolower(a) < towlower (b); } int main() { std::string s {"This is the string to be sorted!"}; std::cout << "Unsorted:\t"" << s << ""\n"; std::sort (s.begin(), s.end(), compare_no_case); std::cout << "Sorted\t:"" << s << ""\n"; }

How do you work with string in c plus plus?
The easiest way is to use a std::string object. #include<iostream> #include<string> int main() { std::string s("hello world"); std::cout<<s<<std::endl; } You can also use C-style character arrays if you don't need the full functionality of a std::string object.
