Sum Of Two Large Numbers In C++ Code Example

Example 1: sum of 2 numbers in cpp

#include<iostream> int add(int,int); int main() { 	using namespace std; 	int a,b; 	cout<<"Enter first number: "; 	cin>>a; 	cout<<"Enter second number: "; 	cin>>b; 	cout<<"Sum = "<<add(a,b); } int add(int x,int y) { 	return(x+y); }

Example 2: sum of two numbers c++

#include<iostream> using namespace std; int main() { 	double number1,number2;   	double sum0;   	sum=number1+number2;   	cout<<sum; }

Example 3: Sum of two large numbers in C++

string sum(string a, string b){     string res="";     while(a.length() < b.length()) a="0"+a;     while(b.length() < a.length()) b="0"+b;     int carry=0;     for(int i=a.length()-1;i>=0;i--)     {         int tmp=a[i]-48 + b[i]-48 + carry;         carry=tmp/10;         tmp=tmp%10;         res=(char)(tmp+48)+res;     }     if(carry>0) res="1"+res;     return res; }
