Question

Design a program in C whose task is to manage the grades of M students in a class in which N quizzes of equal weighting are given during the course of a semester. The program is to do the following in the indicated sequence when the program is executed:

1. Ask the user to type on the keyboard the number of students M and the number of quizzes N, which represent the number of rows and the number of columns, respectively, in a two-dimensional array x[M][N] of floating-point numbers.

2. Ask the user to type on the keyboard the values of all the elements of the array x[M][N], with all of the quiz grades being ? 10 points.

3. Display on the console the M rows and N columns of inputted array element values.

4. Generate and display on the console the elements of a one-dimensional array a[N] where each element of a[N] represents the average grade in the class in each of the N quizzes .

5. Generate and display on the console the elements of a one-dimensional array b[M] where each element of b[M] represents the average grade over the semester of each of the M students .

6. Generate and display on the console the averge grade for the entire class over the entire semester.

Your design is to be in the form of two separate programs:

Program A:This design will perform the above steps without utilizing prototype functions.

Program B: This design will do the same thing as Program A but now the program design will utilize multiple prototype functions.

Explanation / Answer

#include<stdio.h>

main()

{

int m1,m2,m3,total;

float per;

clrscr();

printf("enter 3 nos.");

scanf("%D%D%D",&m1,&m2,&m3);

total=m1+m2+m3;

per=total*100/300;

if(per>=60&&per<=100)

printf("ist");

else if(per>=50&&per<=60)

printf("2nd");

else if(per>=40&&per<=50)

printf("3rd");

else

printf("fail");

getch();

}
