C++ code only

Write a function called setToMin() that will work with the following section of code. It works for any integer variable and will set it to the lowest of the subsequent three integer parameters. You don't need to put in the prototype, but you need to write a complete function. All the variables are integers.

int x, y, z;

setToMin(x, 1, 4, -6);

// the value of x is now -6

setToMin(y, 4, 2, 8);

// the value of y is now 2

setToMin(z, -9, -8, -7);

// the value of z is now -9
