As James Kuyper correctly links downthread, 3DBESNUB was the
problem-solving acronym that my entire cohort at BYU had to use to get
full credit on any physics problem. The first three letters are for
diagrams, but they are in short supply in usenet.
It seems I need code to describe the type of code I want. I honestly
thought I had to come up with a number that wouldn't be smaller in bytes
than whatever I'm storing in a string.
Let me cough up some source and address a specification:
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
int version;
int c;
FILE *fptr, *gptr;
const char *executable1 = "arrow";
const char *executable2 = "mahershala";
const char *base = "toolchain";
const char *ext = "sh";
fptr = fopen("toolchain3.sh","r");
if(fptr == NULL)
{
printf("fopen no bueno");
exit(1);
}
gptr = fopen("toolchain4.sh","w");
if(gptr == NULL)
{
printf("gopen no bueno");
exit(1);
}
while (1) {
c = fgetc(fptr);
if (c == EOF)
break;
else
putc(c, gptr);
}
fclose(fptr);
fclose(gptr);
return 0;
}
I need to concatenate 'toolchain3.sh' from its constituent parts and
then increment it as the filename of gptr.
This lacks the logic for a substitution but sets the stage for it. In
the newly-created .sh file, executable2 shall be substituted for
executable1. Again, for reference, this is our file:
echo 'after preprocessor your program is' >text3.txt
gcc -E arrow.c >>text3.txt
echo 'after compilation avec warnings, output is' >>text3.txt
gcc -Wall -Wextra -o arrow arrow.c >>text3.txt
./arrow >>text3.txt
echo 'source listing is' >>text3.txt
cat arrow.c >>text3.txt
Also, I need a way of determining the natural number that follows
'text'. This is to be substituted by the number appending 'toolchain',
so that the new number is uniform.
Alright, I hope I am clearer now. The BYU cougars did beat undefeated
Gonzaga in college hoops. It was a news event and this is a newsgroup,
where we do a lot of talking about C. It's also basketball season.
How important are substitutions, especially when they are errant? Did
you watch the Oscars?
