Question

i'm having trouble making an else statement that will allow the program to add and output the average the valid numbers inputed into the program.

Here's my output:

Enter Score 1:36

Enter Score 2:-1

Invalid Input

Enter Score 2:89.5

Enter Score 3:42

Enter Score 4:66.3

Enter Score 5:93

You entered: 36.000000, 89.500000, 42.000000, 66.300000, 93.000000

Total Score: 362.800000

Average Score: 72.560000

Max Score: 93.000000

Min Score: 36.000000

Here's my code:

#include <stdio.h>

int main(void) {

double score[5];

double min;

double max;

double total;

double avg;

int i;

max = 0.0;

min = 100.00;

total = 0.0;

for(i=0;i<5;i++) {

printf("Enter Score %d:",i+1);

scanf("%lf",&score[i]);

if(score[i] <0.0 || score[i]>100.00) {

printf("Invalid Input\n");

--i;

}

else{

}

total+=score[i];

if (score[i] > max)

max = score[i];

if (score[i]<min)

min = score[i];

}

avg = total/5.0;

printf("\nYou entered: ");

for(i=0;i<5;i++) {

printf("%lf",score[i]);

if(i<4)

printf(", ");

}

printf("\nTotal Score: %lf",total);

printf("\nAverage Score: %lf",avg);

printf("\nMax Score: %lf",max);

printf("\nMin Score: %lf",min);

printf("\n");

return 0;

}

#include<stdio.h>

#include<limits.h>

float sum(float arr[], int n)

{

    float ans = 0;

    int i;

  

    // compute the sum of array

    for( i = 0 ; i < n ; i++ )

        ans += arr[i];

      

   return ans;

}

float average(float arr[], int n)

{

    float sum = 0;

    int i;

  

    // compute the sum of array

    for( i = 0 ; i < n ; i++ )

        sum += arr[i];

      

    // compute average and return

    return sum / (float)n;

}

float lowest(float arr[], int n)

{

    int i;

    float min = (float)INT_MAX;

  

    // traverse the vector

    for( i = 0 ; i < n ; i++ )

        // if the current element is smaller than min

        if( arr[i] < min )

            min = arr[i];

          

    return min;

}

float highest(float arr[], int n)

{

    float max = (float)INT_MIN;

  

    // traverse the vector

    for( i = 0 ; i < n ; i++ )

        // if the current element is greater than max

        if( arr[i] > max )

            max = arr[i];

          

    return max;

}

int main()

    float arr[5];

    int i;

  

    for( i = 0 ; i < 5 ; i++ )

    {

        // infinite loop

        while(1)

        {

            printf("Enter Score %d: ", i + 1);

          

            // get user input

            scanf("%f", &arr[i]);

          

            // if score is valid

            if( arr[i] >= 0.0 && arr[i] <= 100.0 )

                break;

              

            printf("Invalid Input\n");

        }

    }

  

    printf("You eneterd : ");

  

    for( i = 0 ; i < 5 ; i++ )

        printf("%f ", arr[i]);

  

    printf("\nTotal Score : %f\n", sum(arr, 5));

    printf("Average Score : %f\n", average(arr, 5));

   printf("Max Score : %f\n", highest(arr, 5));

    printf("Min Score : %f", lowest(arr, 5));

    return 0;

}
