Answer 2

In c language we using printf and scanf these function are defined in stdio.h headerfile and many other function are defined in stdio.h . We cannot tell you all function name in one or two lines . Same in c malloc, calloc are defined in stdlib.h headerfile .

We using return `EXIT_SUCCESS` statement which is declared by the header `<stdlib.h>`. It also declares `EXIT_FAILURE`.Unfortunately with a value of 1 in Windows, but its a very long story . If you want to know more about this headerfile you can search on Google. You can find better explanation.
