c++ question. main.cpp is given and the second part needs to be written.

Given a text le (.txt) that contains only two integers (no separation between them). Task: Develop a function SumFromFile that takes the lename, and two integers as input parameters and returns the summation of both integers from reading the file. Note: The two integers passed as parameters should be used to store the values of the integers from the file in NOTE: Some testcases are hidden. Make sure to submit for grading and Check if you have passed the three test cases. 1 #include #include "Questionl.h" 3 using namespace std; 4 5 int main( ) { int to; 7 cin > > tc; 8 string filepath; 9 if (to == 1) { 10 filepath = "Question1_input_file1. txt"; 11 } else if(to == 2) { 12 filepath = "Question1_input_file2. txt"; 13 } else { 14 filepath = "Question1_input_file3. txt"; 15 16 int a, b, c; 17 C = sumFromFile (filepath, a, b); 18 cout 3 #include 4 5 using namespace std; 6 int sumFromFile ( ) { 7 3
