Definition: Source code is the human readable instructions that a programmer writes. Here is an example of some C++ code
void Rectangle::MoveTo (int newx, int newy)
{
x = newx;
y = newy;
}
void Rectangle::RMoveTo (int dx, int dy)
{
x += dx;
y += dy;
}
Programmers use a compiler to turn source code into machine code that the computer can execute.
Some programming languages like JavaScript are not compiled into machine code but are interpreted instead.
