- An automated donation machine accepts donations via 10 or 20 bills to a maximum of $990. The machine needs to print a receipt with the donation amount in English, rather than numerically. Complete the following function which converts any number between 10 to 990 dollars to English.NOTE: You may define and use another function if necessary.NOTE: You should use arrays for this task. Use of switch statements or very long if/else if statements for printing is not allowed. However, using if/else if/else statements for the logic of your algorithm is permitted.NOTE: This function returns the result, and does not print it. Make sure the result is not lost when you return. Example function input and output (donation is 110):Input: 110Output: “one hundred ten dollars” string convertToEnglish (int donation); in C++ #include <iostream>#include <string>using namespace std; string convertToEnglish (int donation); int main() {int donation;cin>>donation;…arrow_forwardWhat value will be returned by the function if a = 8, b=12? %3D int func(int a, int b){ if(a>b){ return a+b; } else if(aarrow_forwardPlease explain this question void main() {int a =300; char *ptr = (char*) &a ; ptr ++; *ptr =2; printf("%d", a); }arrow_forward

This new function should convert a truth value into an integer. In particular, True should be converted into 1 and False into 0. Name the new function integer_0_or_1(). All you need to include below is your definition of the function integer_0_or_1(). It will be tested automatically against relevant inputs. So include your function and nothing more.arrow_forward
