What is the output of the following program segment? int main(){float hours = 8; float payrate = 5.5; // per hourfloat grosspay = 0.0; grosspay = calcgrosspay (hours, payrate); displaygrosspay(grosspay); return 0; }float calcgrosspay(float hrs, float payrt){return hrs * payrt; }void displaygrosspay(float gpay){cout < < "gross pay is "< < gpay < < endl; } a. 44b. gross pay is 44c. gross pay is gpayd. all of the above

The answer is "Option b".

Explanation:

In the code firstly, the main method is declared, inside the main method three float variable is declared, that are "hours, payRate, and grossPay", in which all variable assign a value, that is "8, 5.5, and 0.0". The first two variables are used as parameters, and the third variable is used to hold and pass as a parameter in displayGrossPay function, Then two function is called that is "calcGrossPay and displayGrossPay".

The calcGrossPay function uses "hours and payRate" variable as a parameter, and return multiplication of value.  The displayGrossPay function uses a float variable "gPay" in its parameter, which is held in the grossPay variable, that holds calcGrossPay function value and print, its value.
