Question

OBJECTIVE-C

For this program a teacher needs to be able to calculate an average of test scores for students in their course. Your program must ask the Professor ho many students and how many tests will be averaged per student. Your program should then allow the Professor to enter scores for each student one at a time and then average those scores together. For example, if a student has 5 scores to be entered and the scores are 80, 60, 65,98, and 78 the average should be 76.2%

Here is what I got.

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[])
{

int students, numOfScores, scores, sum;
float average;
NSLog(@"Enter number of students");
scanf("%i", &students);
NSLog(@"Enterh number of scores");
scanf("%i", &numOfScores);
int n;
int s;
for (n = 1; n <= students; n++){
for (s = 1; s <= numOfScores; s++)
{

NSLog(@"Enter the score");
scanf("%i", &scores);
sum = sum + scores;   
}
  
}
average = (float) sum / numOfScores;
NSLog(@"An average score is %f", &average);

return 0;
}

CODE:

#import <Foundation/Foundation.h>

int main (int argc, const char * argv[])
{
   int students, numOfScores, scores, sum;
   float average;
   //take user input
   NSLog(@"Enter number of students");
   scanf("%d", &students);
   NSLog(@"Enterh number of scores");
   scanf("%d", &numOfScores);
   int n;
   int s;
   
   //using loop sum the enter values
   for (n = 1; n <= students; n++)
   {
       sum=0;//reset to 0 for each next student
       for (s = 1; s <= numOfScores; s++)
       {
         
         //add thte scores
          NSLog(@"Enter the score");
          scanf("%d", &scores);
          sum = sum + scores;   
       }
       //find the average and print it
       average=(float)sum/numOfScores;
       NSLog(@"An average score is %.1f", average);
   }


return 0;
}
