I am trying to read in a string from a file (easy enough). But I am then trying to remove the first word or two to be able to save only the trailing information.
Example of inFile text would be:
Where all I want to save to my struct is the ABCDEFG and Mr. XYZ (for different variables).Code:Agency Name: ABCDEFG Agency POC: Mr. XYZ
Scan past the colon and leading whitespace, then copy the rest into a buffer. The strchr() function will take care of the first bit of the task:
Code:#include <stdio.h> #include <string.h> int main(void) { char* text = "Agency Name: ABCDEFG"; char* colon = strchr(text, ':'); if(colon != NULL) puts(colon); }
Is the ":" a useful delimiter?
If so, strchr() is your friend.
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'm thinking that the colon might not be a good delimiter based on a need to provide a time example. I've attached what the input file would look like. I'm thinking of changing the ':' to a '-' to try to make use of strchr().
In my program code, I'm reading in each line using fgets and then a function to remove the trailing new line character.Code:Agency Name: Test Agency POC: Mr. Test POC Phone: 12345 POC Email: [email protected] Aircraft Type: B747 Aircraft Tail: 0000 Aircraft Callsign: HVY123 Arrival Date(**dd/mm/yyyy): 01/01/2021 Arrival Time(**HH:MM Zulu): 15:45 Previous ICAO: KMCO Departure Date(**dd/mm/yyyy): 01/01/2021 Departure Time(**HH:MM Zulu): 19:00 Next ICAO: KADW Inbound Passengers(Number): 247 Inbound DV(Number): 0 Inbound Cargo(Details): None Inbound HAZMAT(Details): None Outbound Passengers(Number): 240 Outbound DV(Number): 17 Outbound Cargo(Details): None Outbound HAZMAT(Details): None
Could I use the strchr function on the struct element?Code:fgets(new->AgencyInfo.AgencyName, 100, inFile); removeNL(new->AgencyInfo.AgencyName);
I believe I found it!
Thank you for your help getting me looking in the right direction!Code:fgets(buf, 100, inFile);removeNL(buf); token = strtok(buf, s); t = strtok(NULL," "); strcpy(new->AgencyInfo.AgencyName, t);
