Answer:
// here is code in C++.
#include <bits/stdc++.h>
using namespace std;
// main function
int main()
{
    // variables Declaration and initialization
    int no_gallon=16;
    int dis=312;
    // find the miles per gallon
    double mile_gallon=dis/double(no_gallon);
    // print the results
    cout<<"number of gallons: "<<no_gallon<<endl;
    cout<<"distance travel before refueling: "<<dis<<endl;
    cout<<"miles per gallon is: "<<mile_gallon<<endl;
return 0;
}
Explanation:
Declare and initialize the number of gallon and distance travel without refueling. Calculate the miles per gallon by dividing distance with number of gallons.Then print the results.
Output:
number of gallons: 16
distance travel before refueling: 312
miles per gallon is: 19.5 
 
        
             
        
        
        
Answer:
A complex wave is a wave made up of a series of sine waves; it is therefore more complex than a single pure sine wave. This series of sine waves always contains a wave called the "FUNDAMENTAL", that has the same FREQUENCY (repetition rate) as the COMPLEX WAVE being created.
Examples for complex wave:
<em>• The Square wave
</em>
<em>• The Triangular wave
</em>
<em>• The Saw-tooth wave</em>

Answer:
The code will produce:-
2.4
Explanation:
In this code the result of the arithmetic operation is stored in the variable c.On evaluating the expression it divides 12.0 by 5 which results in 2.4 and it is stored in float variable c.Then it is printed on the screen using print statement.Since the c is double variable so the result will be a decimal number.
Hence the answer is 4.
