Problem 1: (Hint:  Use a sequential structure)

How do you calculate the miles you are getting per gallon of gasoline if you record the mileage readings from your car’s odometer each time you fill up the gas tank?  Two odometer readings should be inputted, one reading is before you fill up the gas tank, and the second reading is when you refill the gas tank.  The third input is the quantity of gallons of gasoline purchased when the gas tank is refilled.  After inputting these 3 values, calculate and output:

Expert Solution
Step 1

Answer - 1

 

Problem 1:

 

Input: 

 

1. Reading of odometer before fill up the tank (O1)

 

2. Reading of odometer when refill the tank (O2)

 

3. Quantity of gallons of gasoline (Q)

 

Output:

 

1. The miles traveled between gas refils

 

    Algorithm: Miles travel = Reading of odometer when refill the tank (O1) - Reading of odometer before fill up the tank (O2)

 

2. The average miles per gallons based on the miles traveled and the amount of gasoline purchased after the time the gas tank is refilled

 

  Algorithm: Average miles = Miles travel / quantity of gallons of gasoline (Q)

 

CODE:

 

#include<stdio.h>

int main()

{

    float O1,O2,Q;

    printf("Reading of odometer before fill up the tank:");

    scanf("%f",&O1);

    printf("Reading of odometer when refill the tank:");

    scanf("%f",&O2);

    printf("Quantity of gallons of gasoline:");

    scanf("%f",&Q);

    printf("The miles traveled between gas refills:%f",O2-O1);

    printf("\nThe average miles per gallons on the miles traveled and the amount of gasoline purchased after the time the gas tank is refilled:%f",(O2-O1)/Q);

    return 0;

}
