C in 100 Seconds: Same Data Different Output — Format Specifiers | Episode 3

Seven format specifiers in 100 seconds. Same number, different specifier, different output.

%d prints decimal. %x prints hex. %.2f controls decimal places. %s prints strings. %p shows the memory address. %10d pads to ten characters
wide. %-10d left-aligns. printf is how C talks to the screen — the format specifier tells it how.
