Question

I thought knowing all built-in functions is helpful to be good coder in c++! What do you think you too? Share me your helpful ideas on comments below!

Answer 1

There are many built in functions, list is very long , lets start with
cout , cin ,gets , puts , .........
Under iostream.h header file.

Then getchar , putchar , toupper , tolower , .......
Under ctype.h

Then strchr, strlen, strcat, strcpy , .........
under String.h

Then log , abs, fbs, ceil floor sqrt, pow , sin ,cos ,sinh , asin ,.......
Under math.h

Then system, clrscr, .......
Under conio.h

These are most general function we use ,still these are less , we can have many more function but they are rarely used.....

Similarly many more
