In C++, you cannot call undeclared function in C++, compiler will show you error like "undeclared identifier".Compiler has not seen a declaration for it.Hence,the compiler has no idea what you are referring to because it hasn't seen it before.

What is the actual size of INT in the C language, 2 or 4 bytes?
The actual size to int is determined by the compiler as the program runs. But theoretically the size is 2 bytes. You can increase the size by adding keyword long infront of it to make the size 4 bytes. Eg int a; // 2 bytes Long int b; // 4 bytes
