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;
stack<char> a2;
stack<int> result;
stack<int> temp;
int carry = 0;
string num1;
string num2;
cout << "Enter first number (both numbers should have equal digits)" << endl;
getline(cin, num1);
cout << "Enter second number" << endl;
getline(cin, num2);
for (int i = num1.size()-1; i >= 0; i--) {
a1.push(num1[i]);
a2.push(num2[i]);
}
while (!a1.empty() && !a2.empty()) {
int element = (int)a1.top() + (int)a2.top() + carry;
cout << element;
if (element > 10) {
element %= 10;
carry = 1;
}
result.push(element);
cout << result.top() << endl;
a1.pop();
a2.pop();
}
string abc;
while (!result.empty()) {
temp.push(result.top());
result.pop();
abc += temp.top();
}
cout << abc;
}
I know i have definitely made a logical mistake , but i can’t get it , can anyone please guide me?
the following is the output am getting
