Find Largest Figure And Figure Less Than 20% Of Largest

Dave O'Dea · April 2017

Hi, I have written some which needs to:
- read in 200 floating point numbers that
represent the sales figures of 200 sales staff.
- once the 200 numbers have been read in code should find the largest individual sales figure
- code should then use this value to display all those sales figures which are less than 20 % of the highest value.

Here is my code so far, however, for largest it currently only prints the last entry scanned in ...

      int main() {
        float sales[200], lowsales = 0, largest, limit, lower;
        int i, l, j, k, num;

        printf("Enter no of figures:");
        scanf("%d", & num);

        for (l = 0; l < num; l++) {
          printf("Enter sales figure # %d: ", l + 1);
          scanf("%f", & sales[i]);
        }

        largest = sales[0];

        for (j = 0; j < num; j++) {
                    if (sales[i]>largest) {
                        sales[i] = largest;
            // printf("Inline largest: %f\n", largest );
          }
        }
        printf("largest: %f\n", largest);

        printf("\nSales figures which are less than 20 per cent of largest sales:\n");
        limit = largest * (0.2);
        for (k = 0; k < num; k++) {
          if (sales[i] < limit) {
            lowsales = sales[i];

          }
          printf("lowsales: %f\n", lowsales);
        }

        //system("pause");
        return 0;
      }

This the output I get from this code:

        Enter no of figures:4
        Enter sales figure # 1: 7979.999
        Enter sales figure # 2: 8989.777
        Enter sales figure # 3: 3.455
        Enter sales figure # 4: 5959.555
        largest: 5959.555176

        Sales figures which are less than 20 per cent of largest sales:
        lowsales: 0.000000
        lowsales: 0.000000
        lowsales: 0.000000
        lowsales: 0.000000

Could I ask if anyone would mine to please help me correct what I have done so far ?

Solved:

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

int main()
{
    float sales[200], lowsales=0, largest, limit, lower;
    int Count1, Count2, Count3, num;

    printf("Enter no of figures:");
    scanf("%d", &num);

    for (Count1=0; Count1<num; Count1++)
    {
        printf("Enter sales figure # %d: ",Count1+1);
        scanf("%f",&sales[Count1]);
    }

    largest = sales[0];

    for (Count2=0; Count2<num; Count2++)
    {
        if (sales[Count2]>largest)
        {
            largest = sales[Count2];
        }
    }
    printf("%f\n", largest); //added this just to check that it is setting largest correctly

    printf("Sales figures which are less than 20 per cent of largest sales:\n");
    limit = largest*0.2;
    for (Count3=0; Count3<num; Count3++)
    {
        if (sales[Count3]<limit)
        {
            lowsales = sales[Count3]; //you just had them in wrong order ;-)
            printf("%f\n",lowsales);
        }
    }
    //system("pause");
    return 0;
}
