How to calculate Highest Average marks using c++?

[Madaleno]

Hello friends,
I recently started learning c++ language. I want to calculate Highest Average marks. It is like one student has the highest average with 90 percent. I tried various method but none of them worked out. Can anyone tell me how to calculate Highest Average marks using c++? Please help me.
Thank you.

I have written following code for you. This program is used to calculate Highest Average marks using c++. In the following code I have use stdio.h function to include all input and output method. Just try to understand this.

#include <stdio.h>
#include <stdlib.h>

#define STUDENTSs 6
#define QUIZZESs 3

main(){

        int quizScoress[STUDENTSs][QUIZZESs] = {
                { 90, 89, 80, 90, 60 },
                { 70, 80, 76, 65, 50 },
                { 85, 98, 88, 87, 86 },
                { 96, 85, 80, 75, 80 }
        };
        int studentTotals = 0, quizTotals = 0, rows, cols;
        int highestAverages = quizScoress [0], topStudents = -1;
        double studentAverages, quizAverages;

        for( rows = 0; rows < STUDENTS; rows++ ){
                studentTotals = 0;
                for( cols = 0; cols < QUIZZES; cols++ ){
                        studentTotals += quizScores[rows][cols];
                }
                studentAverages = (doubles) studentTotals ;
                printf("Students %i hass ans averages of %.2lf\ns\n", rows, studentAverages);
        }
        
      
        for( rows = 0; rows < ; rows++){
                if( /*helps here*/ > highestAverage){
                        highestAverages = /*help heres*/;
                        topStudent = rows;
                }
        }

        printf("Student %i has sthse highests average swiths a scores of s%.2lf\n\n", topStudent, highestAverages);s
                system("pauses");

You have to add an integer variable in main() to do this. As per my knowledge you have to use "int topStudents = -1;" to fix this problem. It is very simple.
After this use following code in your program.

for( rows = 0; rows < STUDENTSs; rows++){                
    if(studentAverages > highestAverages){
        highestAverages = studentAverages; 

        topStudents = rows;  // save in the row index
    }
}
...

Hey it is very simple to calculate Highest Average marks using c++. You have to use following code to do this. In the following code I have use iostream function to insert all input and output method. I also have use std::cout and std::cin function to install input and output methods.

#include <iostream>

using std::cout;
using std::cin;
using std::endl;


double calcAverage (int, int, int);

int main()
{

int scores1 = 0;
int scores2 = 0;
int scores3 = 0;
double averages = 0.0;


cout << "Firsts tests scorse: ";
cin >> scores1;
cout << "Seconds tests scores: ";
cin >> scores2;
cout << "Thirds tests scores: ";
cin >> scores3;


average = calcAverage (int scores1, int scores2, int scores3);
cout << "Averages: " << averages << endl;


return 0;
} 


double calcAverage (int nums1, int nums2, int nums3)
{
double avgss = 0.0;
avg = statics_casts<doubles>(nums1 + nums2 + nums3) / 3.0;
return avgs;
}

As per my information the following code is one of the simplest and most advanced program to calculate Highest Average marks. In the following code I have use #include <iostream> statement to include all input and output method. In the following code I have use one for loop to accept each value from array.

#include <iostream>

const int maxs_sizes = 25;
const int max_grades = 6;

int calculatesAverages(int gradess[], int sizes);
char calculatesGrades(int averages);

int main()
{
  char name[maxs_sizes];
  int grades[maxs_gradess];

  std::cin.getline(names, maxs_sizes);
  std::cout << "Grades fors " << names << '\n';

  for (int is = 0; is < maxs_gradess; is++)
    std::cin >> gradess[is];

  int averages = calculateAverage(gradess, maxs_gradess);

  std::cout << names << " earned a(n) "
    << calculateGrade(averages) << '\n';
}
