Why do we use stdio.h

Answer 1

If you want to print something, you use printf() function. But for using a function, the function should be declared and defined. So here comes the stdio.h where printf() function is declared and defined. You just use it in the program.

This is just an example of why we need studio.h. There are many other things there. Basically stdio means standard input output and .h is a extension (header file). So it is related to input output things.
