Thread: Code to calculate "mode"

I'm trying to create a function to calculate the mode of 11 items entered into an array. Can anyone help me with this? Thanks!

You need to give us more information about what you want to do

Sorry, I'm new here...

I have to write a program that inputs 11 floating point values from the keyboard, then print our the numbers in ascending order along with the mean, median and mode of the array. I figured out everything but the mode. I attached my code.

Well, I tried to attach it...here, I'll include it instead:


# include <stdio.h>
# define INPUT 11

// --- Prototypes ---
void getData(float A[]);
void bubblesort(float A[]);
void printOutput(float A[]);
void mean(float A[]);
void median(float A[]);
void main(void)
{
int stop;
float A[INPUT];

getData(A);
bubblesort(A);
printOutput(A);
mean(A);
median(A);

scanf("%i", &stop);
}

// Function: getData
// Precondition: None
// Postcondition: Fills array with numbers input by user
void getData(float A[])
{
int count;

for (count = 0; count < INPUT; count++)
{
printf("Enter number %2i: ", count + 1);
scanf("%f", &A[count]);
}
}

// Function: bubblesort
// Precondition: Floating point array
// Postcondition: Array is sorted in ascending order
void bubblesort(float A[])
{
int i, j, didswap;
float temp;

for (i = 0; i < INPUT; i++)
{
didswap = 0;
for (j = 0; j < INPUT - i; j++)
if (A[j] > A[j + 1])
{
temp = A[j];
A[j] = A[j + 1];
A[j + 1] = temp;
didswap = 1;
}
if (didswap == 0)
break;
}
}

// Function: printOutput
// Precondition: Sorted floating point array
// Postcondition: Prints elements of sorted array
void printOutput(float A[])
{
int i;

printf("\nSorted array follows:\n");
for (i = 0; i < INPUT; i++)
{
printf("%.2f ", A[i]);
}
printf("\n\n");
}

// Function: mean
// Precondition: Sorted floating point array
// Postcondition: Prints mean of sorted array
void mean(float A[])
{
int count;
float sum = 0;

for (count = 1; count <= INPUT; ++count)
{ sum += A[count - 1];
}

printf("Array Mean : %.2f", sum /= INPUT);
}

// Function: median
// Precondition: Sorted floating point array
// Postcondition: Prints median of sorted array
void median(float A[])
{
printf("\nArray Median : %.2f\n", A[5]);
}
