Now I am looking at line 11 and I don't see anything i am doing wrong. So I was woundering if someone can help me understand what I might be doing wrong thanks. $buyscandybar=.55

C lang - sprintf creates 8 char-long string instead of 6, when applied to negative int
Date : March 29 2020, 07:55 AM
it should still fix some issue sprintf(string, "%06x", -1); prints at least 6 characters. %x implies an unsigned number. (unsigned) -1, in hex, is FFFFFFFF on a 32-bit unsigned machine.
When scanf() gets to the "%06x", "The unsigned int argument is converted to unsigned octal (o), unsigned decimal (u), or unsigned hexadecimal notation (x or X) in the style dddd; ..." C11dr ยง7.21.6.1 8

sprintf in C giving wrong output
Date : March 29 2020, 07:55 AM
To fix the issue you can do I recommend to use arrays of char and pass them to your function as parameter. You local array char firstName[MAX_STRING]; goes out of scope if getFirstName terminates. This meas the variable is not longer accessible after getFirstName has terminated and a pointer to the variable is undefined behaivoir. #include <stdio.h>
#define MAX_STRING 10
void getFirstName( char *firstName )
{
printf("Please enter your first name: ");
fflush( stdout );
fgets( firstName, MAX_STRING, stdin );
}
void getLastName( char *lastName )
{
printf("Please enter your last name: ");
fflush( stdout );
fgets( lastName, MAX_STRING, stdin );
}
void getNickName( char *nickName )
{
printf("Please enter your nick name: ");
fflush( stdout );
fgets( nickName, MAX_STRING, stdin );
}
void getCompleteName (
char* completeName,
const char* firstName,
const char* lastName,
const char* nickName)
{
sprintf(completeName,"%s \"%s\" %s",firstName,nickName,lastName);
}
int main ()
{
char firstName[MAX_STRING];
char lastName[MAX_STRING];
char nickName[MAX_STRING];
char completeName[MAX_STRING*3+10];
getFirstName( firstName );
getLastName( lastName );
getNickName( nickName );
getCompleteName( completeName, firstName, lastName, nickName );
printf("Hello %s.\n",completeName);
return(EXIT_SUCCESS);

Creating path using CGMutablePath creates line to wrong CGPoint

I wish this help you I was planning to display information of AR object in screen with arrow in 2D. So I used projectPoint to get corresponding position of object in screen. I have this function to return convert 3D position of node to 2D and CGPoint to display info text in. , path.addLine(to: s) s here had reversed y so this did the trick let frame = self.sceneView.frame
let sInversed = CGPoint(x: from.x, y: frame.height - s.y)
path.addLine(to: sInversed)
