Subana is writing a program which will calculate the mean average of a set of numbers by adding the numbers and dividing the result by the amount of numbers. She will use a variable, avg, to store this average. Which variable type would be most suitable for avg?


a variable of type "double" is more suitable for finding average because average could be any number with decimal places. we can't use a variable of type "integer" because it will omit the value after the decimal and will not produce satisfactory results.  


an example of C++ code is given to find the average of two numbers a and b

#include <iostream>;

using namespace std;

int main() {

double a = 2.334;

double b = 34;

double average =  (a + b) / 2;

cout << average;

return 0;
