C programing    Given the function below, what would the function call question3(10, 101) return? int question3(int a, int b) { if (a == 0) return b; if (b == 0) return a; return question3(10*a+b%10, b/10); }

Thank you soo much!

AHPA #9:A Gas Station• You have been asked to create a C program to manage the gaspumps at a gas station. The station has four pumps connectedto four tanks with capacities: 100, 75, 50, and 150. Every timea car fills up it takes 10 gallons. You’ll know that a car hasarrived because the carArrived function will return with apump number. After a car has filled up, print out the currentcontents of all four tanks.• Write a C program that can track each of the four tanks. Updatethe amount of gas remaining in a tank when a car fills up.When a tank gets to less than 20 gallons of gas remaining,make a call to request a refill truck visit the station(refillRequest). This will cause the tank to berefilled automatically

What does the function f do? struct Point2D { double x; double y; struct Triangle { Point2D v1; Point2D v2; Point2D v3; }; void f(Triangle&t) { } int temp = 12.5; temp = t.v1.x; t.v1.x = t.v1.y; t.v1.y = temp; } int main () { Triangle mytri; mytri.v1.x = 1.0; mytri.v1.y = 22.5; f (mytri); Swaps values of x and y in vertex 1 of an argument of type Triangle Initializes value of x in vertex 1 of an argument of type Triangle Sets all x,y values in all vertices of an argument of type Triangle Swaps value of x in vertex 1 with value of x in vertex 2, for an argument of type
