hi, very new to C programming. i have opened a data file which has 380 decimal numbers ranging from .90 - 1. i need to first round these number to two decimal places then sort label them into categories (.90-.92 = 1 ,.93-.94 = 2, and so on.) i need to be able to save the data file so i can manipulate it, and this is where i am stuck!
So where are you stuck?
- reading the file
- rounding to 2dp
- allocating to bins
- writing the results.
Post some code.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
i have rounded the data to 2 decimals, now i am trying to turn the data file into an array where i can the label them 1 - 5 and keep a frequency count.Originally Posted by Salem

How about a series of if / else if tests for the ranges ?

i have all the ranges sorted but i don't know how to open the data file and edit it so i can label each number 1-5
Code:if (grade <.92 ) printf("\n data=%5.2f, score=%c", grade, '1'); else if (grade <.94 ) printf("\n data=%5.2f, score=%c", grade, '2'); else if (grade < .96) printf("\n data=%5.2f, score=%c", grade, '3'); else if (grade <.98) printf("\n data=%5.2f, score=%c", grade, '4'); else if (grade <1.01) printf("\n data=%5.2f, score=%c", grade, '5'); }
Well if you've mastered printf(), then you should be able to do the same with fprintf()
