pls help just started learning c++ and cant get my head around how to do this:
write prog for data logger which records one reading per day at a specific time for 5 days.the logger records in the format:n1805071500
the first letter preceding the numbers can mean one of below
n= normal
g=high
l=low
the rest are day,month,year,time.
the info can be extracted in the form of text filecontaining 5 lines

x=missed/invalid

  • prog to display welcome msg
  • TO DISPLAY ALL DATA ON SCREEN IN TABLE FORM BY COMMAND T(HINT USE\t for tabs)
  • should show bar chart on command G,showing number of occurremcesof normal,high,low,missed measuremnts in the form of *,each asterik representingone instance
  • user should request for particular days using command D
  • Exist using command Q
  • any command other than T,D,G,Q will result in error and request for new input

GIVEN CODEREADS LINES FROM TXT FILE"LOG.TXT" AND STORES EACH CHARACTER INDIVIDUALLY IN A 2D ARRAY WHERE THERE ARE 11 COLUMNS AND 5 ROWS.ONE ROW OF CHARACTERS FOR EACH DAY
#include<stdio.h>
main()
/* variable declarations*/
FILE* f;
char s[57];
char v[5][11];
int i,j,k;
/*initialise variables*/
i-0;
j=0;
k=0;
/*open file fore reading*/
f=open("log.txt","r");
/*until end of file is reached*/
while (fgets (s,57,f)!=NULL)
{
do{
/*add file character to array column*/
v[j]=s[k];
/*move on one array column*/
j++;
k++;
/* for 11 characters in one row*/
}while (j<12);
/*move to next row*/
i++;
/*set column counters back to zero*/
k=0;
j=0;
}
/*close file*/
fclose(f);
PLEASE HELP IN CREATING CODE
**********my attempt is shown below***********************************
/*program to input datalogger results*/

Just wondering how are you doing the time part? Are you using the time library or an OS specific function?

First off, you might want to put this in the C++ section, and also put the code into [ code ] tags, because the code is hard to use otherwise.

I'll look this over in a little bit.

>which records one reading per day at a specific time for 5 days.

Er, I was just wondering do you actually have to do the above, or just parse the info from your text file?
