# WAP in C++ to calculate sum of series 1.2+2.3+3.4+4.5+

The Program in C++ to calculate sum of series 1.2+2.3+3.4+4.5+ is given below:

``````#include <iostream>
using namespace std;

int main() {
double sum = 0;
for (int i = 1; i <= 5; i++) {
sum += (i * 1.0) * (i + 1);
}
cout << "Well, the Sum of the series is: " << sum << endl;
return 0;
}
``````

## Output:

Well, the Sum of the series is: 70

## Pro-Tips💡

This program uses a for loop to iterate from 1 to 5 and calculate the sum of the series 1.2 + 2.3 + 3.4 + 4.5 + 5.6.

The variable “sum” is initialized to 0 and is incremented with each iteration of the loop.

The final sum is printed to the console using the cout statement.
