The #include statement in C and C++ is used to incorporate (include) a file in the compilation unit at the point where the #include statement is encountered. It is used to incorporate commonly used files, often (but not always) rarely changed files, so that the developer does not need to incorporate common code more than once in a project.
#include <stdio.h> static int myvar1, myvar2; int main (void) { puts ("It was easy"); return 0; }
By learning how to program on C+.
#include<
To swap two variables without using a third variable, use exclusive or manipulation... a ^= b; b ^= a; a ^= b;
Ax + By = C By = -Ax + C y = (-A/B)x + C/B
#include<iostream> int main() { std::cout << "Your name"; }
#include <iostream> int main() { std::cout << "a plus bi" << std::endl; return 0; }
#include ...double x, y;...y = cosh (x);
#include <libraryname>
Yes.
Yes.
#include <iostream> int main() { printf( " *\n***\n *\n" ); return( 0 ); } Output: *****
#include "what-its-name-is.h"
Nothing. In C++ you could write a C compiler. So, everything that can be done with C, can be also done in C++.
If you want to know about adding new header files, then it is simple. Write your functions in a file. Save that file with extension .h in the include directry. Now, you can include this file using the #include directive
Write a function that print a triangle of stars.
#include <stdio.h> static int myvar1, myvar2; int main (void) { puts ("It was easy"); return 0; }
