what is the objective of the following program? what will the program output if the user inputs the English name Peter?

  

#include #include using namespace std; int mystery2(const char [], int); int main() { int size; char string1[80]: cout < < "please enter your English name: "; cin > > string1: size = strlen(string1); cout < < mystery2 (string1, size) < < endl; return 0: }
