Question

Write a templated function sumList that will take in an array of any type and the length of the array. It should add all the elements in the array and return the total.
Hint: you can declare a variable sum of type T and initialize it like this:

T sum {};

The {} are the best way to make sure that numbers get set to 0, a string gets created as empty etc...

#include <iostream>

using namespace std;

//Do not modify anything on or above the line below this
//YOUR_CODE_BELOW

//YOUR_CODE

//YOUR_CODE_ABOVE
//Do not modify anything on or below the line above this

int main()
{
int nums[] = {4, 2, 8, 7};
string words[] = {"hello", "there"};

cout << sumList(nums, 4) << endl;
cout << sumList(words, 2) << endl;

return 0;
}

Answer 1

#include <iostream>

using namespace std;

//Do not modify anything on or above the line below this
//YOUR_CODE_BELOW

//YOUR_CODE
//Generic Function which finds the maximum element of an array
template <class T>
T sumList(T* arr,int size) {
T sum;
//Iterating over the array to find the maximum element
for(int i=0;i<size;i++)
{
sum+=arr[i];
}
return sum;
}

//YOUR_CODE_ABOVE
//Do not modify anything on or below the line above this

int main()
{
int nums[] = {4, 2, 8, 7};
string words[] = {"hello", "there"};

cout << sumList(nums, 4) << endl;
cout << sumList(words, 2) << endl;

return 0;
}
