Answer:
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.  
Explanation:
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;
}
