Question 47

The program in Figure 1 needs to be changed so that it repeats four times using definite (count-controlled) iteration.

Figure 1

Console.Write("Enter a score: ");
int score = Convert.ToInt32(Console.ReadLine());
if (score >= 50) {
    Console.WriteLine("Pass");
}
else {
    Console.WriteLine("Fail");
}

Select one option that does this correctly.

A
for (int count = 0; count < 4; count++) {
    Console.Write("Enter a score: ");
    int score = Convert.ToInt32(Console.ReadLine());
    if (score >= 50) {
        Console.WriteLine("Pass");
    }
    else {
        Console.WriteLine("Fail");
    }
}
B
for (int count = 0; count <= 4; count++) {
    Console.Write("Enter a score: ");
    int score = Convert.ToInt32(Console.ReadLine());
    if (score >= 50) {
        Console.WriteLine("Pass");
    }
    else {
        Console.WriteLine("Fail");
    }
}
C
int count = 1;
while (count <= 4) {
    Console.Write("Enter a score: ");
    int score = Convert.ToInt32(Console.ReadLine());
    if (score >= 50) {
        Console.WriteLine("Pass");
    }
    else {
        Console.WriteLine("Fail");
    }
    count = count + 1;
}
D
int count = 4;
while (count > 0) {
    Console.Write("Enter a score: ");
    int score = Convert.ToInt32(Console.ReadLine());
    if (score >= 50) {
        Console.WriteLine("Pass");
    }
    else {
        Console.WriteLine("Fail");
    }
    count = count - 1;
}
