Igot a simple problem that i've already asked about before
but the answear i got didn't work. I want to open JPEG files
in C and was told to open the file as usual but using binary
like this;
I know its real easy for you wiz's but i havent found anythingCode:#include<stdio.h> main() { FILE *ptr; ptr=fopen("c:\\test.jpeg","rb"); if(ptr==0){ printf("didnt work"); getchar();} else fclose(ptr); return 0; }
that can answear my simple question!!
What didn't work? What error are you getting?
Add this to your code and see what you get:
Code:if(ptr==0){ printf("didnt work"); perror("Error"); getchar();}
ok
so perror tells me "no such file or directory found" however at the same time i can see
the image file there!!
And the code works fine with a txt file in the same location. I dont see any reason for perror to tell me what its telling me!?!
Are you absolutely sure the image file is in the root of C and called exactly what you have in the code? Is the image perhaps called test.jpg, and not .jpeg?
All the buzzt!

thanks cornedBee.
The extension was JPG and not JPEG.
Another of my little problems solved.
Thanks for the help guys. I owe you one:-)
It is for this reason I like to use this kind of skeleton.
Code:#include <stdio.h> int main(void) { static const char filename[] = "c:\\test.jpeg"; FILE *file = fopen( filename, "r" ); if (file != NULL) { /* do stuff */ fclose( file ); } else { perror( filename ); } return 0; } /* my output c:\test.jpeg: No such file or directory */
7. It is easier to write an incorrect program than understand a correct one.
