Problem in reading .png file in C

[Efficience]

Hello Everyone ,
I have written a simple piece of code for reading an Image file(.png) in c but this code doesn't seem to work properly.Can anyone help me solve this problem of reading an image file in C.Code I have written is :-

     FILE *file;
     char ch;
     
     file=fopen("img.png","r");     
     
     while((ch=fgetc(file))!=EOF )
              printf("%c ",ch);

When running this code , each time I'm getting the same output as
ë P N G
Even if the file size is 2022bytes .Why am I not getting 2022 bytes ? Instead I'm getting only these 4 bytes as output.Please !! help.

PNG files are binary. Most of the characters are non-printing characters, so printf won't work unless you output the hex value of the character. So try this:

ILE *file;
     char ch;
     
     file=fopen("img.png","r");     
     
     while((ch=fgetc(file))!=EOF )
              printf("%.02x ", ch);

Hi
First of all if you are reading from the png file and writing it in the form of characters , then you might not see all the bytes, as the png file is a binary file and many of the bytes will not be printable character. You will get EOF if some data of the png file is -1 and it will come out of the loop. you can do it like :

FILE *file;
char ch;
long size,i;
file=fopen("img.png","r");     
fseek(file,0,SEEK_END);
size=ftell(file);
fseek(file,0,SEEK_SET);
for(i=0;i<size;i++)
{
ch=fgetc(file);
printf("%x ",ch);
}
