random generator of chars help

[jmnp86]

how do i make a random generator so that my program can randomly choose from an array of operations? I know that it is not right, but I don't really know how to fully do it so I kind of made some things things up

this is part of my code in my .cpp file

{
  Problem result;
  char problem.m_arithmOp[4] = {'-','+','%','*'};
  srand( (unsigned)time(0));
  for(int i=0; i<1 ; i++)
  {
   result.m_arithmOp[i] = (rand()%3)+1;
  }
  return result;

and this is my struct in my header

struct Problem
{
  int m_number1;
  int m_number2;
  int m_answer;
  int m_level;
  char m_arithmOp;
} problem;

Your 'op' is a single char, not an array.

So try something like
result.m_arithmOp = "+-*/"[rand()%4];
