Question

In this stage you should read all of the data into internal structures suitable for use in the later stages and create an output representation that provides an overview of the data that was read.

please write a code that will execute such function & generate a required output (as stated on the question). Input data is not required to write a code but if you need to know the headerline, please refer to photo 3.

Stage 1- Reading the Data (Marks up to 9/20) In this stage you should read all of the data into intermal structures suitable for use in the later stages, and create an output representation that provides an overview of the data that was read. Input will come from a comma-separated-values file, with each input line (after the first header line) looking like: IDCJAC0001,086039,2000,01,28.2,Y IDCJAC0001,086039,2000,02,34.5,) IDCJACO001,086039,2000,03,22.5,Y IDCJAC0001,086039,2000,05,96.3,Y IDCJACO001,086039,2000,06,42.4,)Y IDCJACO001,086039,2000,07,45.1,Y recording, for example, that the rainfall measured at site 086039 (Flemington Racecourse, in Melbourne) in January 2000 was 28.2 millimeters. The last value in each line is Y or N to indicate whether the data has been "validated". To read one line, you should use the format control string with suitable receiving variables, and then skip any remaining characters on that line until a newline character has been consumed. Note that IDCJAC0001 ís a fixed string that identifies the type of data, and will appear in all data files that your program will process. You may assume that the lines in the input are always in ascending-year then ascending-month order, but also need to be aware that there may be missing data lines. For example, there is no data for April 2000 in the test file shown above. Missing values are completely typical of sensor-based data, and occur because of equipment malfunction, network errors, and so on A sample of the required output of this stage is: mac: ass2-soln < rainfall-086039-2000-2009.csv S1, site number 086039, 115 datalines in input S1, 2000: Jan Feb Mar ..May Jun Jul Aug Sep Oct Nov Dec S1, 2001: Jan Feb Mar ..May Jun Jul Aug Sep* Oct Novs Dec

Answer 1

CODE:

#include<stdio.h>
int main()
{
char line[512];
char *months[] = {"", "Jan", "Feb", "Mar", "Apr", "May", "Jun",
"Jul", "Aug", "Sep", "Oct", "Nov", "Dec"};
int id[11],yr,mo[11],i=0,j;
char c[11];
char str[] = "IDCJAC0001";
double r[11];
FILE *info; // create info pointer
info = fopen("val.csv","r"); // open text file called info, read
fscanf(info,"%d, %d, %d,%lf,%c" ,&id[i], &yr, &mo[i], &r[i], &c[i]);
//printf("\n%s\t,%d\t, %d\t, %d\t, %lf\t, %c\t",str,id[i],yr,mo[i],r[i],c[i]);
i++;
while(fgets(line, 512, info) != NULL)
{
fscanf(info,"%d, %d, %d,%lf,%c" ,&id[i], &yr, &mo[i], &r[i], &c[i]);
//printf("\n%s\t,%d\t, %d\t, %d\t, %lf\t, %c\t",str,id[i],yr,mo[i],r[i],c[i]);
i++;
}
printf("\n");
fclose(info);
printf("\nmac: ass2-soln < rainfall-086039-2000-2009.csv\nS1, sitenumber 086039, 115 datalines in input\n");
printf("S1, 2000: ");
for(j=0;j<i;j++)
{
if(mo[j]-mo[j-1]!=1)
{
int x = mo[j]-mo[j-1],k;
for(k=1;k<x;k++)
printf("\t...");
if(c[j]=='Y')
printf("\t%s",months[mo[j]]);
else
printf("\t%s*",months[mo[j]]);
}
else
{
if(c[j]=='Y')
printf("\t%s",months[mo[j]]);
else
printf("\t%s*",months[mo[j]]);
}
}
printf("\n");
return 0;
}

I took a sample input of what you provided:

086039,2000,01,28.2,Y
086039,2000,02,34.5,Y
086039,2000,03,22.5,Y
086039,2000,06,42.4,Y
086039,2000,07,45.1,Y
086039,2000,08,45.1,Y
086039,2000,09,45.1,Y
086039,2000,10,45.1,Y
086039,2000,11,45.1,N
086039,2000,12,45.1,Y

Output for it is:

gcc stages.c ./a.out mac: ass2-soln< rainfal1-086039-2000-2009.csv S1, sitenumber 086039, 115 datalines in input Dec S1, 2000: an $I

For another input:

086039,2000,01,28.2,Y
086039,2000,02,34.5,Y
086039,2000,03,22.5,Y
086039,2000,05,96.3,Y
086039,2000,06,42.4,Y
086039,2000,07,45.1,Y
086039,2000,08,45.1,Y
086039,2000,09,45.1,Y
086039,2000,10,45.1,Y
086039,2000,11,45.1,N
086039,2000,12,45.1,Y
