Here's the line of code with the warning
Code: if((addressbook[3][num][4]=='-')&&(strlen(addressbook[3][num])=='10'))
Or what might be the possible causes of such a warning?
Here's my code. The error's at the last line.
Code:
#include <stdio.h>
#include <string.h>
#include <ctype.h>
#define max_con 30
void add_contact();

I keep getting this warning message and I do not know how to fix it. Is it because I'm using char to instead of strings to replace all 't' with 'lp'?

Can distinguish between character constant and string constant giving examples

I'm doing some file input/output work here in C and received this warning during compilation (GCC). My research indicates that this error is in response to white space or a character cancellation function or something like that. I'm not 100% sure exactly what it means. My code works fine, but the following warning does appear.
Code:
warning: unknown escape sequence: '40'
Here's my code (excluding a bunch of comments at the bottom of the file).
Code:
#include <stdio.h>
int main(void){
FILE *file;
file = fopen("Running Practice.c", "a");
fprintf(file, "Testing...
");
fclose(file);
}
I believe the error I received has to do with either the ' ' I used when appending text to my file, or something to do with there being a space in the file name itself.
I'm working on my program that takes input of the employees' first and last name, their payrate, their deferred from check and also the amount of hours they have worked which then the gross is calculated and also the taxes are calculated by an external function. In the program design it is necessary to put arrays which I have done, but when i compile I receive warning messages
Code: warning: format '%s' expects argument of type 'char*', but argument 3 has type 'double'
Warning: format '%f' expects a matching 'double' argument [-Wformat] which I believe is causing my program to just give me garbage when I run it. What do those warnings mean?

I have a function that I want to exit gracefully when an "error" occurs in an input file. My function declaration is:
Code: BSTnode *buildTree(FILE *fp)
The few lines that are causing the problems are:
Code: if(regcomp(®ex, to_find, REG_EXTENDED | REG_NEWLINE) != 0) {
fprintf(stderr, "Failed to compile regex '%s'
", to_find);
return EXIT_FAILURE;
}
I know that if I just use "return" by itself the warning goes away but fails to exit when the error occurs. I also believe this may not be the correct use of stderr. But I need the program to exit when an error has occurred.
recently I wanted to add some warning message when imputing date (DD.MM.YY) is older than some pre-set value.
day DD
month MM
year YY
pre-set date 21.7.2014
The condition I have is
if((YY < 2014) ||
(YY == 2014 && MM < 7) ||
(YY == 2014 && MM == 7 && DD < 21){
//warning message
}
Now I was just curious if there is easier way to implement this condition. To use less code. When I extend the condition to hour:minute:second the code would only grow fast. Also I know I should not use "magic numbers" but it is only for the demonstration.
I have to optimize a code for below scenario. I am reading stdin (a file redirected to stdin) character by character. How many chars are going to come is not known. After every few chars there is a seaparator. e.g $ as below
rhhrkkj$hghjhdf$ddfkrjt
While reading, if the separator arrives I'm processing the string stored before that separator and then continue reading stdin in same fashion, till EOF. I am using getc(stdin) to read chars.
Using gprof I can see most of the program time is spent inside main() , for this reading logic. Rest of the program is just some insert and search operations. I am getting time of 0.01 secs at the moment, want to reduce further.
How do I write an a program that will read an input file character by character?
