Thread: Function Question

Code:

#include<stdio.h>
 
int calcAbvAvg(int marks[10], int avg)
{
    int students = 0;
    int i;
 
    for(i=0;i<10;i++)
    {
        if(marks[i] > avg)
        {
            students++;
        }
    }
  printf("Students above average = %d",abv_avg);
    printf("Students below average = %d",10 - abv_avg);    
}
 
main (void)
{
    int marks[10];
    float avg;
    int min = 100;
    int max = 0;
    int tot = 0;
    int count;
    int abv_avg = 0;
 
    for (count=0;count<10;count++)
    {
        printf("Enter marks for student %d",count+1);
 
        while(scanf("%d",&marks[count) != 1)
        {
            printf("\nWrong input\nEnter marks for student %d",count+1);
            fflush(stdin);
        }
 
        if(min > marks[count])
        {
            min = marks[count];
        }
 
        if(max < marks[count])
        {
            max = marks[count];
        }
    }
 
    for (count=0;count<10;count++)
    {
        total += marks[count];
    }
 
    avg = total/10;
    abv_avg = calcAbvAvg(marks, avg);
 
    printf("Minimum marks = %d",min);
    printf("Maximum marks = %d",max);
    printf("Average marks = %0.2f",avg);
  calcAbvAvg(marks, avg);
 
}

I suck at function and linked list

can u help me with this question! the only problem i am having in this question is the function calcAbvAbg() not working! i want that function to display the students who are above and below average!

Code:

printf("Students above average = %d",abv_avg);
    printf("Students below average = %d",10 - abv_avg);

I think you meant to put students instead of abv_avg..

1. FAQ > Why fflush(stdin) is wrong - Cprogramming.com
2. Don't use magic numbers (e.g. 10) - use named constants instead (e.g. #define MAX_MARKS 10)
3. You should heed compiler warnings. In fact, I got several warnings and errors when I tried to compile your code:

Code:

main.c||In function 'calcAbvAvg':|
main.c|15|error: 'abv_avg' undeclared (first use in this function)|
main.c|15|error: (Each undeclared identifier is reported only once|
main.c|15|error: for each function it appears in.)|
main.c|20|warning: return type defaults to 'int'|
main.c||In function 'main':|
main.c|33|error: expected ']' before ')' token|
main.c|52|error: 'total' undeclared (first use in this function)|
main.c|25|warning: unused variable 'tot'|
||=== Build finished: 5 errors, 2 warnings ===|

You're trying to use a variable "abv_avg" in your "calcAbvAvg()" function, but that variable doesn't exist that function.

Also, on line 33, you have a closing parenthesis ')' where a closing bracket is supposed to go ']'.

I didn't look too much further into your code. Fix up the warnings/errors so it compiles, and post your updated code.
