your code::blocks may be has some problem reinstall it....then build your code but remember when you write main function you should write " int main " and should have a return value again before build it, you must save your program a name and add ".c" or ".cpp" here is a hello world code

using namespace std; int main{ cout<<"Hello World"< Hello.cpp

i think it will be helpful for you. Source(s): mine check your operating system...if its not xp and u r using xp compiler than this problem arise. so either change your window OS to XP or make a bootable c/c++ compiler in cd and run on any OS. I m not sure you can check this trick.moznu mollick
