The behaviour of allowing the following code to compile: cin >> x; int a[x];
by gcc/g++ is due to historical reasons. This kind of a declaration is called a variable length array however it is not supported by the C++ and C standards. To prove that this is the case, recompile with g++ -pedantic <file.cpp> You get: vla.cpp:8:9: warning: ISO C++ forbids variable length array ‘a’ -- DK -- You received this message because you are subscribed to the Google Groups "Algorithm Geeks" group.
