C++

Implement ONLY the following function given the pre and post conditions.. (Note: including additional code than the function will impact grade). A precondition is what should be true before calling a function to get the correct results. A post condition is what is true AFTER the function is done.

// Precondition : items is an array of count strings // Postcondition : Returns the total number of characters // contained within the array. // For example, if we call: // char_count(['Exam','Apple','moat','SCOUT'],4) will return 18 unsigned long char_count(std::string words, unsigned long count);
