Dead code is code in the source code of a program which is executed but whose result is never used or a code that can never be reached or used.
Dead code is code in the source code of a program which is executed but whose result is never used or a code that can never be reached or used.
Dead code is waste of computing power and might result of unexpected behavior to the program.
Examples:
int foo (int a, int b)
{
int c = a + b; // dead code - executes and result never used
return a - b;
}
void foo ()
{
bool a = true;
if (!a)
{
// dead code - never called
}
}
