Thread: Listing Scores in descending order, by using the selection sort

Hello. This is what in my .txt document.

Code:

Lab  1: 10
Lab  2: 18
Lab  3: 22
Lab  4: 19
Lab  5: 14
Lab  6: 16
Lab  7: 18
Lab  8: 18
Exam 1: 65
Exam 2: 42

I would like to list those number in descending order without changing which test it is:

Let say Lab 1 is 10 points. After listing it in descending order, it would still be Lab 1: 10.

The output would look like this for example:

Lab scores in sorted order:

22 19 18 18 18 16 14 10


How would I go about doing this?



My current code:

Code:

#include <stdlib.h>
#include <stdio.h>
#include <iostream>
#include <ctype.h>
#define MAX 8


void main (void);
void function1 (void);
void function2 (void);

void main (void)
{
    function1();
}


void function1 (void)
{
    FILE *in;
    char var;
    float lab [];
    float test [];

    if (( in =  fopen ("grades.txt", "r")) == NULL)
    {
        printf ("Error Opening File");
        return;
    }
    
 
    while ((fscanf(in, "%c", &var)) != EOF)
    {
    
        printf ("%c", var);
        if (var == ':')
            fscanf (in, "%f %f %f %f %f %f %f %f %f %f", &lab[1], &lab[2], &lab[3], &lab[4], &lab[5], &lab[6], &lab[7], &lab[8], &test[1], &test[2])
    }
    printf ("\n");
}
