Write a function that accepts two integers as input arguments and return their sum. Call this function from main( ) and call another function from main( ) that prints the result (sum). Thus, you need two separate functions besides main( ). C++

Then Modify the program below by replacing the function prototype "void getScore(int& score);" with "int getScore();"

You need to modify other part of program according to this change.

//This program reads a course score and prints the //associated course grade #include using namespace std; void getScore (int& score); void printGrade (int score); int main () int courseScore; cout
