//Placethedefinitionofyourfunctiontoprintthescoreshere
// Add a function to print the scores so that each student's labs appear // on a separate line of output. Your output should be labeled as follows: Student 1: 80 90 70 100 60 90 85 78 93 80 70 98 89 94 Student 2: 98 85 100 99 89 90 72 0 78 98 100 65 0 56 Student 3: 85 60 25.... //there should be a nested loop //outer loop controls which student(row) is being read

Explanation / Answer

void PrintScores(const int labScores[][MAX_LABS], int numStudents, int numLabs)
{
int student, lab;

//outer loop controls which student(row) is being printed
for(student=0; student<numStudents; student++)
{
cout << "Student " << (student+1) << ":";
// inner loop controls which lab(column) is being printed
for(lab=0; lab<numLabs; lab++)
{
cout << " " << labScores[student][lab];
}
cout << endl; // new line after each student
}
}
