A C++ problem about arrayI am a beginner of C++ programming. When I am learning the array, I copied a program from a book and cannot be executed. I don't know what is wrong? Please help me!!! #include void main() { int max_element(); int n, a[10]; int max; for(n=0; n>a[n]; max=max_element(a, 10); cout (more...)
