Consider the following program written in C syntax:

void swap (int a, int b) {
int temp;
temp = a;
a = b;
b = temp;
}
void main () {
int value = 2, list [5] = {1, 3, 5, 7, 9};
swap (value, list [0]);
swap (list[0], list[1]);
swap(value, list[value]);

for each of the following parameter-passing methods, what areall of the values of the variables value and list after each of thethree calls to swap?

a. Passed by value
b. Passed by reference
c. Passed by value-result

Apump is used to circulate hot water in a home heating system. water enters the well-insulated pump operating at steady state at a rate of 0.42 gal/min. the inlet pressure and temperature are 14.7 lbf/in.2, and 180°f, respectively; at the exit the pressure is 60 lbf/in.2 the pump requires 1/15 hp of power input. water can be modeled as an incompressible substance with constant density of 60.58 lb/ft3 and constant specific heat of 1 btu/lb or. neglecting kinetic and potential energy effects, determine the temperature change, in °r, as the water flows through the pump.
