//Lista de intrebari

0- How many different colors does GIF format support? ---256 max
1- Which of these formats supports animation? ---GIF
2- What’s the difference between lossy and lossless compression? ---Lossless writes the data in a more efficient way, while lossy is optimised for file size
3- Which of these formats is lossy-compressed? ---JPEG
4- What happens, technically speaking, when a file is deleted on a FAT file system? ---The system modifies the filename's first character to signal that it has been deleted and that the directory entry can be recycled
5- What can someone like you do to ensure (with high probability) that files you delete cannot be recovered? ---Write NUL bytes (or random characters) to every address on the disk
6- What’s stdint.h? ---A bunch of typedefs and macros for making integer variables of custom sizes
7- What’s the continent you are living in? ---Europe
8- How many primary colors? ---3
9- What is love? ---Baby don't hurt me
10- What’s the difference between green and blue? ---yellow
11- What does it mean if biHeight is negative? --- If biHeight is negative, the bitmap is a top-down DIB with the origin at the upper left corner
12- What field in BITMAPINFOHEADER specifies the BMP’s color depth (i.e., bits per pixel)? ---biBitCount
13- Why might fopen return NULL in copy.c:37? ---If it can't find the file, it will
14- Why is the third argument to fread always 1 in our code? ---Because it specifies how many elements you want to read
15- What value does copy.c:70 assign padding if bi.biWidth is 3? ---The padding would be 3, because 3 pixels * 3 bytes per pixel * 3 padding = 12, which is a multiple of 4
16- What does black do? ---Obscures the light
17- What is Tm? ---Timis
18- What is the meaning of life? ---39
