C++ code

Both images below are under the same number (1a and 1b)

Please provide code for whole program and function only to both 1a and 1b.

Implement a function void copyWord(char " destination, const char " source, int numChars); that copies characters from the C-string source into the array destination. The number of characters to be copied is stored in the parameter numChars . After copying the characters, your code should add a null terminator to destination, so that it can be used as a C-string. For example, if source contains the C-string "hi there" and numChars is 2, then the first three elements of destination will be 'h', 'i' and 'no'. Notice in the example we only copied 2 characters from source not 3. The third character, '10', is added by your code. RULES: No local variable allowed and no function calls allowed. Here is the driver used to test your code: Write a function with prototype int addDigits(char num[]) that returns the sum of the digits in a C-string num, which contains all digit characters, i.e. '0', '1', '2', '3', '4', '5', '6', '7', '8', or '9'. (If we just added num[0] + num[1] + nums[2] that would give the sum of ASCII values for '4', ' 3 ' and '6' which would be much bigger than 13 !) RULE: No function calls allowed. The main used to test your code looks like this: int main(){ char t[10] cint; cout
