Question

Implement a C program to calculate the Average Score Point(ASP) of a student taking N courses in a

semester. Ask the user for the number of courses(N) the student is taking in the semester, and check if the

number of courses is greater than 1 (>1). If the number of courses is less than or equal to 1(<=1), display

an error and ask the user to try again until the right input is entered.

Next, ask the user for the student score for each course. Use the student score entered to determine the

equivalent score point. Use the Table 1 scale below to assign a point to each score.

To calculate the ASP, sum up the score point for the courses and divide by the Number of courses (N).

Once you have calculated the ASP, make a comment on the student transcript based on this ASP using the

Table 2 to determine the comment for each ASP

. Call the functions listed below to implement each of

the operations described above

.

Implement the following functions for the lab assignment:

int courseNumCheck(int)-

Takes the user input as an argument (integer type) and checks if the number of

courses is greater than 1. Returns 1 if true else 0.

float getScore(void)

–

Takes no argument, and Returns the course score input by the user.

float getScorePoint(float)

– Takes the course score as an argument (float type) and Returns the score point.

void printComment(float)

– Takes the ASP as an argument (float type) and prints the comment associated

with an ASP.
