Miscellaneous Coding Tidbits
To get input from data files:
Include stdio.h as a header file, declare a FILE * variable, use fopen to connect the FILE * variable to your physical file. See references further below for C file I/O examples.
To deal with reading strings correctly from files:
When reading a string after reading a number from a file, you may need to read a junk character out between reading the number and the string. Use the getc(file_pointer) command to read one character from a file. If one doesn't work try using two getc commands.
To compile multiple physical files into a single program:
To compile two files (Ex: L41.c and L42.c) together into a single
program, use the gcc command with both file names following. Example:
myomega>gcc L41.c L42.c
To get time and date information for your program using C functions:
Information and an example using localtime(), time(), and the struct tm are available at
