Part I- 2 Dimensional Arrays Write a C program called finalgrades.c. Your program should declare a 2-dimensional array with 5 rows and 4 columns (you should use named constants so these values can be changed). Your array will represent the exam scores for a student. The first three columns will hold the scores for three exams which will be entered by the user. The fourth column will contain the average of the exam scores which your program should calculate. After all of the scores have been entered and the averages have been calculated, your program should output a result table with row and column labels like in the sample output below. (output continued on second page) Please enter exam #1 score for student #1: 77 Please enter exam #2 score for student #1: 88 Please enter exam #3 score for student #1: 99 Please enter exam #1 score for student #2: 67 Please enter exam #2 score for student #2: 68 Please enter exam #3 score for student #2 : 87 Please enter exam #1 score for student #3 : 75 Please enter exam #2 score for student #3: 67 Please enter exam #3 score for student #3: 88 Please enter exam #1 score for student #4 : 99 Please enter exam #2 score for student #4 : 98 Please enter exam #3 score for student #4 : 100

Explanation / Answer

float exam_marks[5][4];
int score=0;
int average=0;
int i=0,j=0;
  
for(i=0;i<5;i++)
{
average = 0;
for(j=0;j<3;j++)
{
printf(" Please Enter the exam #%d score for student #%d:",j+1,j+1);
scanf("%d",&score);
exam_marks[i][j]=score;
average = average + exam_marks[i][j]; // calculate average for each row
}
exam_marks[i][3] = average/3;
}
  
/****************Display Final Score****************/
printf(" FINAL SCORE ");
printf(" 1 2 3 AVG ");
  
for(i=0;i<5;i++)
{   
printf("#%d",i+1);
for(j=0;j<4;j++)
{
printf(" %.2f",exam_marks[i][j]);
}
printf(" ");
}
