+# Accumulate
+
+**Description :** 
+- This function returns the sum of all the values lying in a range between [first, last) with the variable sum. 
+- Usually the sum of elements in a particular range or a complete array is found using a linear operation which requires adding all the elements in the range one by one and storing it into some variable after each iteration.
+
+**Example** :
+
+```cpp
+#include <bits/stdc++.h>
+#include <vector>
+#include<numeric>
+
+int main() {
+    std::vector<int> v = {3, 13, 27};
+    int sum = 7;
+    std::cout << "Result using accumulate: ";
+    std::cout << accumulate(v.begin(), v.end(), sum);
+ 
+	return 0;
+}
+```
+**[See Sample code](https://github.com/deepanshumidha5140/30-seconds-of-cpp/blob/master/snippets/vector/accumulate.cpp)**
