Looking for help in a C code!

[mindriotus]

What I am trying to understand, is how do I add a function to summarize the rainfall for each year, using the following code as the foundation. What would I need to add, and where in order to accomplish this? Also if you could please explain briefly as well it would be highly appreciated!


Thank you so much!!!


The code:

insert

// C code
#define NUMMONTHS 12
#define NUMYEARS 5
#include <stdio.h>
// function prototypes
void inputdata();
void printdata();
// Global variables
// These are available to all functions
float Raindata[NUMYEARS][NUMMONTHS];
char years[NUMYEARS][5] = {"2011","2012","2013","2014","2015"};
char months[NUMMONTHS][12]
={"Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"};
int main ()
{
 char enterData = 'y';
 printf("Do you want to input Precipatation data? (y for yes)\n");
 scanf("%c",&enterData);
 if (enterData == 'y') {
 // Call Function to Input data
 inputdata();


 // Call Function to display data
 printdata();
 }
 else {
 printf("No data was input at this time\n");
 }
 printf("Please try the Precipitation program again. \n");
 return 0;
}
// function to inputdata
void inputdata() {
 /* variable definition: */
 float Rain=1.0;
 // Input Data
 for (int year=0;year < NUMYEARS; year++) {
 for (int month=0; month< NUMMONTHS; month++) {
 printf("Enter rain for %d, %d:\n", year+1, month+1);
 scanf("%f",&Rain);
 Raindata[year][month]=Rain; 

 }
 }
}
// Function to printdata
void printdata(){
// Print data
 printf ("year\t month\t rain\n");
 for (int year=0;year < NUMYEARS; year++) {
 for (int month=0; month< NUMMONTHS; month++) {
 printf("%s\t %s\t %5.2f\n",
years[year],months[month],Raindata[year][month]);
 }
 }
}

What you need to add is a function called say summarisedata()

Where you need to add it, is everywhere you see printdata()

Eg.

// function prototypes
void inputdata();
void printdata();
void summarisedata();

Have you learnt anything about programming yet, or does your tutor just give you 'fill in the blank' exercises.
In other words, where did you come by this code?
Because if you wrote it yourself, the question is stupidly simple for you to solve.

Edit:
Oh, here's where you found your code.

Yeah, unfortunately I was given 'fire and forget' type of material and I was given a fill in the blank exercise. I work 50 hours a week and nights so it's hard to get help, forums are the best way if at all possible.

I've been playing with it this morning and this is where I am not now...

#include <stdio.h>

#define NUMMONTHS 12
#define NUMYEARS 5

// function prototypes
void inputdata();
void printdata();
 
// Global variables
// These are available to all functions
float Raindata[NUMYEARS][NUMMONTHS];
int sum = 0;
int avgsum = 0;
char years[NUMYEARS][5] = {"2011","2012","2013","2014","2015"};
char months[NUMMONTHS][12] ={"Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec"};

int main ()
{
  char enterData = 'y';
  printf("Do you want to input Precipatation data? (y for yes)\n");
  scanf("%c",&enterData);
  if (enterData == 'y') {
    // Call Function to Input data
    inputdata();
 
     // Call Function to display data
     printdata();
   }
   else {
     printf("No data was input at this time\n");
   }
   printf("Please try the Precipitation program again. \n");
 
   return 0;
}

// function to inputdata
void inputdata() {
  /* variable definition */
  float Rain=1.0;
   // Input Data 
   for (int year=0;year < NUMYEARS; year++) {
      for (int month=0; month< NUMMONTHS; month++) {
          printf("Enter rain for %d, %d:\n", year+1, month+1);
          scanf("%f",&Rain);
          Raindata[year][month]=Rain;
      }
    }
}

// Function to printdata
void printdata()
{
    // Print data
    sum = 0;

    printf ("year\t month\t rain\n");
    for (int year=0;year < NUMYEARS; year++)
    {
        for (int month=0; month < NUMMONTHS; month++)
        {
            sum += Raindata[year][month];
            printf("%s\t %s\t %5.2f\n", years[year],months[month],Raindata[year][month]);
        }
    }

    printf("Total rain of all five years combined: %d\n", sum);
    printf("Average sum of each individual year: %d\n", avgsum);
}

So now I have the sum of all the months functioning properly... how can I get the individual sum for each individual month 1-5?

Well there's nothing wrong with re-ordering the loops.

    for (int month=0; month < NUMMONTHS; month++)
    {
        for (int year=0;year < NUMYEARS; year++)
