I need to match a float inside a very long string (about 5000 chars) with sscanf. (I trimmed the string in this example.) I can't seem to match all the chars that come before and after the float.
int main(void)
{
char A = "";
strcat(A, " hello world! WORD' name='5.3498' hello world! ... (1 Reply)
sscanf does not stop at the first "&". How can I extract "doe" ?
char A = "name=john&last=doe&job=vacant&";
char B = "last";
char C = "";
char *POINTER = strstr(A, B);
sscanf(POINTER + strlen(B), "=%s%*", C);
printf("%s\n", C); // doe&job=vacant& (2 Replies)
How can I separetely extract the string and int after "dribble" ? (sscanf must limit TEXT to 9 chars to avoid buffer overflows.)
How come this code does not work with "dribbletext08" but does with "dribbletext05" ?
int main(void)
{
char TEXT = "";
int NUMBER = 0;

ppmtopgm - convert a portable pixmap into a portable graymap
SYNOPSIS
ppmtopgm [ppmfile]
DESCRIPTION
Reads a portable pixmap as input. Produces a portable graymap as output. The output is a "black and white" rendering of the original
image, as in a black and white photograph. The quantization formula used is .299 r + .587 g + .114 b.
Note that although there is a pgmtoppm program, it is not necessary for simple conversions from pgm to ppm , because any ppm program can
read pgm (and pbm ) files automatically. pgmtoppm is for colorizing a pgm file. Also, see ppmtorgb3 for a different way of converting
color to gray. And ppmdist generates a grayscale image from a color image, but in a way that makes it easy to differentiate the original
colors, not necessarily a way that looks like a black and white photograph.
QUOTE
Cold-hearted orb that rules the night
Removes the colors from our sight
Red is gray, and yellow white
But we decide which is right
And which is a quantization error.
