Question

As described in the function prototype comment, this function takes two arguments, a single-dimension character array of scores (E/M/R/N) and an integer designating the size of the array, and returns an integer indicating the next homework number (zero-based) the student should submit. If any score is 'R' or 'N', then the index of the first such score is returned. Next, if any score is an 'M', then the index of the first such score is returned. Finally, if all the scores are 'E's (which will be the case if neither of the previous conditions is satisfied), then return a -1 indicating that no assignments need to be redone.

Note that you will need to make two passes over the provided scores, first looking for 'R' or 'N', and next looking for 'M'. As you consider your loops (in this function and others), ask yourself which type of loop is best suited for the situation (for, while, or do-while).

To test each homework score you will need some form of branching. As you work on this function note that there are three ways it can return, one for an 'R' or 'N', one for an 'M', and one for all 'E's.

code:

// Function: getNextResubmission // Precondition: homeworkScores is an array of length size

// Postcondition: Returns the homework number the student should resubmit.

// The suggested homework should be the first homework assignment

// that the student scored a R or N. // If all homework has an M or E, then the suggested homework

// should be the first M. // If the student has all E's, then return -1.

int getNextResubmission(char homeworkScores[], int size){ }

* Main program */

int main() {

// define an array for student names

string names[CLASS_SIZE] = {"Ava", "Brook", "Caryon", "Daniel", "Emma", "Perfect"};

// define an array for student ids

long ids[CLASS_SIZE] = {142001, 142002, 142003, 142004, 142005, 777777};

// define a 2D array of scores char homeworkScores[CLASS_SIZE][NUMBER_OF_SCORES] = {

{'E', 'E', 'E', 'E', 'M', 'N', 'E', 'R', 'E', 'M', 'N', 'R', 'R', 'N'},

{'M', 'M', 'E', 'M', 'M', 'R', 'R', 'M', 'R', 'N', 'N', 'N', 'N', 'N'},
