two sum 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: two sum problem in c++
bool twosum(int A[], int N, int X) {
sort(A, A+N);
int i = 0, j = N-1;
while (i < j) {
if (A[i] + A[j] == X) return true;
else if (A[i] + A[j] > X) j--;
else i++;
}
return false;
}
Example 3: sum of two numbers c++
#include<iostream>
using namespace std;
int main()
{
double number1,number2;
double sum0;
sum=number1+number2;
cout<<sum;
}
