Write the definition of a void function with three reference param- eters of type int, double, and string. The function sets the values of the int and double variables to 0 and the value of the string variable to an empty string. (6, 7, 8)

Question 12 options:

void sumAvg(double x, double y, double z, double& sum,

double & avg, string& result)

{

sum = x + y + z;

avg = sum / 3;

if (avg >= 70)

result = "Pass";

else

result = "Fail";

}

void sumAvg(double x, double y, double z, double& sum,

double & avg, string& result)

{

sum = x - y + z;

avg = sum / 3;

if (avg >= 70)

result = "Pass";

else

result = "Fail";

}

void sumAvg(double x, double y, double z, double& sum,

double & avg, string& result)

{

sum = x + y + z;

avg = sum / 3;

if (avg > 70)

result = "Pass";

else

result = "Fail";

}

void sumAvg(double x, double y, double z, double& sum,

double & avg, string& result)

{

sum = x + y + z;

avg = sum * 3;

if (avg >= 70)

result = "Pass";

else
