Unreachable Code - Examples

Examples

Consider the following fragment of C code:

int foo (int iX, int iY) { return iX + iY; int iZ = iX*iY; }

The definition int iZ = iX*iY; is never reached as the function returns before the definition is reached. Therefore the definition of iZ can be discarded.

Famous quotes containing the word examples:

    Histories are more full of examples of the fidelity of dogs than of friends.
    Alexander Pope (1688–1744)

    It is hardly to be believed how spiritual reflections when mixed with a little physics can hold people’s attention and give them a livelier idea of God than do the often ill-applied examples of his wrath.
    —G.C. (Georg Christoph)

    No rules exist, and examples are simply life-savers answering the appeals of rules making vain attempts to exist.
    André Breton (1896–1966)
