A function adds a list of numbers and returns the sum. The function head is:

• int sum(int list)

• void sum(int list)

• void sum(int *a, int b)

• int sum(int *a, int b)

A function adds a list of numbers and returns the sum. The function head is:

• float sum(float list)

• void sum(float list)

• void sum(int *a, int b)

• float sum(float *a, int b)

This loops through a string:

• for (int i=0; i<100; i++)

• for (char a= 0; a < 100; a++)

• for (int i=0; str[i]!='\0'; i++)

• for (int i=0; i!='\0'; i++)

Consider a void function called stuff(). Which of the following is a legal call to stuff()?

• stuff();

• int x = stuff()

• cout << stuff();

• stuff() = 8;

Consider a function called stuff(). Stuff takes an integer and returns a Boolean. Which of the following is a legal call to stuff()?

• stuff();

• if (stuff(8) == False)

• cout << stuff();

• stuff(2) = true;

A function called stuff() takes an integer and changes its value. A possible function head is:

• int stuff()

• void stuff(int a)

• int & stuff()

• void stuff(int &a)

A function called stuff() changes the values in a list. A possible function head is:

• int stuff()

• void stuff(char *a)

• int * stuff()

• void stuff(int &a, int b)

With the function head:

bool stuff(int *a, int b, char c)

a, b and c are:

• parameters of the function

• arguments of the function

• data types of the function

• return types of the function

A function takes a word and replaces the letter at a certain position with another letter. The function head is possibly:

• void stuff(char *a, int b, char c)

• char stuff(word, letter, number)

• void stuff (char *a, int c, char &c)

• int stuff (char word, char letter, int n)

A function takes a word and replaces the letter at a certain position with another letter. The function call is possibly:

• word = stuff(letter);

• stuff(word, letter, 8);

• cout << stuff (word, letter);

• int stuff (char word, char letter, int n)
