A C++ program consists of one or more source files.Source files contain function and class declarations and definitions.

Files that contain only declarations are incorporated into the source files that need them when they are compiled.

Thus they are called include files.

Files that contain definitions are translated by the compiler into an intermediate form called object files.

One or more object files are combined with to form the executable file by the linker. www.myassignmenthelp.net5A Simple C++ Program#include #include using namespace std; int main ( ) {intx, y; cout > x >> y; int sum = x + y; cout > input operator (extractor)
