C++ Simple addition calculator not working

Hey guys can someone tell me why my code won't work, keep getting error messages. I'm an absolute beginner and it's only my second day working on C++. It's just an attempt at a simple addition only calculator. #include <iostream> using namespace std; int main () { int a,b; int sum; cin>> a; cout<<"enter another number\n"; cin b; cout<< "sum is:"<<sum<<endl; return 0; }

harry It should be like this 👇👇👇 #include <iostream> using namespace std; int main () { int a,b; int sum; cout<<"enter a number\n"; cin>> a; cout<<"enter another number\n"; cin>> b; sum = a+b; cout<< "sum is:"<<sum<<endl; return 0; }

you had only declared variable called sum...you had not assigned any value to that sum variable... Complier don't know what you are going to store in sum variable... that you were missing... and cout statement to enter number is not must... it is just used as information to user
