Report Card V4 - Multiple Students in C++

Practice

Combine lists, loops, and conditionals to print a letter grade for each student in a class.

You start with:

vector<string> names = {"Alice", "Bob", "Carol", "Dan"};
vector<int> scores = {92, 78, 85, 67};

Build:

Alice: A
Bob: C
Carol: B
Dan: D

Rules:

  • Loop over the indices of the students (names.size()) so you can read the name and the score at the same position.
  • Use the same scale as V3: 90+ A, 80-89 B, 70-79 C, 60-69 D, below 60 F.
  • On each iteration print the name, a colon and a space, then the grade, for example Alice: A.

Use vector<string> and vector<int> with index loops.

vector<string> names = {"Alice", "Bob", "Carol", "Dan"};
vector<int> scores = {92, 78, 85, 67};

for (int i = 0; i < (int) names.size(); i++) {
    int score = scores[i];
    string grade;
    if (score >= 90) {
        grade = "A";
    } else if (score >= 80) {
        grade = "B";
    } else if (score >= 70) {
        grade = "C";
    } else if (score >= 60) {
        grade = "D";
    } else {
        grade = "F";
    }
    cout << names[i] << ": " << grade << endl;
}
