Today I was asked a what might look like simple or obvious question but a bit challenging for me to answer

The question was '' why do c/c++ programs start with #include ''

#include is a preprocessor directive which tells the preprocessor to include the code from the given library, if it is a standard library it should be Surrounded with <> for example <stdio.h> but if it is not in standard library it should be surrounded with “” for example “testlib.hpp”

C. You don't have to include stdlib.h but if you don't then you won't have very much to work with! Sr.No. Functions 1 printf() 2 scanf() 3 getc() 4 putc() 5 fopen() 6 fclose() 7 remove() 8 fflush() Means you might still have getchar() putchar() to use, maybe that could be a challenge for our future?
