Thread: finding highest average

I'm trying to figure out the code to determine the student with the highest average. I got this far but now I'm stuck.

Code:

#include <stdio.h>
#include <stdlib.h>
#define STUDENTS 4
#define QUIZZES 5

main() {

	int quizScores[STUDENTS][QUIZZES] = {
		{ 90, 90, 90, 90, 90  },
		{ 90, 80, 70, 60, 50  },
		{ 90, 89, 88, 87, 86  },
		{ 90, 85, 80, 75, 70  }
	};
	int studentTotal = 0, quizTotal, row, col;
	double studentAverage, quizAverage;

for (row = 0; row < STUDENTS; row++) {
	studentTotal = 0;
	for ( col = 0; col < QUIZZES; col++) {
		studentTotal += quizScores[row][col];
	}
	studentAverage = (double) studentTotal / QUIZZES;
	printf("Student %i has average %.2lf\n", row, studentAverage);
}
	
for ( col = 0; col < QUIZZES; col++){
	quizTotal = 0; 
	for( row = 0; row < STUDENTS; row++){
		quizTotal += quizScores[row][col];
	}
	quizAverage = (double) quizTotal / STUDENTS;
	printf("Quiz %i has average %.2lf\n", col, quizAverage); 
}
	
//for (


	//printf("Student %i has the highest average with a score of %.2lf\n", row, studentAverage);

		
		system("pause");
}

What's the problem?

I need to write code to determine which student has the highest average. So far I found the averages for all students and all quizzes but I can't figure how to find the highest.

Make 2 variables.

highest_student and highest_score

Initialize highest_score to 0.

Go through each student, if the score is higher than highest score, set highest_student to that student, and highest_score to their score.

Or you can just use the one variable highest_student and compare the highest student's average with the current student's average.

how is it that you can find the average of a set of numbers -- complete with #defines and floating point casts -- but cant find the highest value of a set of numbers?

did you try?

did you even write the code you posted?

Hey guys thanks for your help! Figured it out.
