Question

Please help solving these following questions:

Convert 18210 into binary (or into hex).

Convert 3276810 into binary (or into hex).

Convert E7A216 into binary or decimal.

Convert 11100101102 into decimal (or into hex).

• Understand or code a function that uses default parameters.

• Describe or use a group of overloaded functions.• Write a function to find the average of a 1-dim array of floats.

• Write a function to multiply two 1-dim arrays together to produce a third array (dot product)(e.g., a[5] = { 10, 20, 30, 40, 50 }; b[5] = { 3, 5, 0, 2, 4 };  compute c[5] = { 30, 100, 0, 80, 200 } ).

• Write a function to convert a cstring array to all lowercase or all uppercase letters(e.g. for example, “CSC 2430 Data Structures” is converted to “csc 2430 data structures”).

• Write a function to remove all blank characters from a cstring array(e.g., “ Here is    my String “      “HereismyString” )

• Write a function to copy one cstring array to another cstring array.

• Write a function to convert a cstring array that contains a string of digit characters into thecorresponding integer value (e.g., “1234” gets converted to the int value 1234).- Remember, the character digit ‘5’ can be converted to numeric value (‘5’ – ‘0’),  and “1234” means                                           ( ( (1)*10 + 2) * 10 + 3) * 10 + 4which can be computed in a loop.

• Write a function to count the number of “words” in a cstring (where words are separated by blanks)(e.g., “I am Mike, you’re    one of    my friends.”   has 8 words).• Write a function to determine the location of a particular substring value within a larger string(e.g., where is the substring “The” located in the cstring “Hi There” ?    answer: position 3).

• Write a function to compare two cstring values to determine which one has the larger alphabeticvalue (e.g., “a” vs “abc”, or “abc” vs “ABC”, or “Hi There” vs “Hello”, or “A1” vs “A23”, etc).
