Im trying to have all the miles added together and all the gallons added together then divide. For this code I have to have it add as many as I want until I input -1 in for gallons. I have this code correct for the most part its just that its not adding all the miles and all the gallons up. I have counter and counter1 counting how many times I've entered a mile and gallon.
Code:#include <stdio.h> int main () { float miles; float gallons; int total; float tmiles; float tgallons; float taverage; float average; int counter; int counter1; total = 0; counter = 0; counter1 = 0; printf("Enter the gallons used (-1 to end): "); scanf("%f", &gallons); printf("Enter the miles driven:"); scanf("%f", &miles); average = miles / gallons; printf("The miles / gallons for this tank was %f\n\n", average); while(gallons != -1) { tgallons = total + gallons; tmiles = total + miles; printf("Enter the gallons used (-1 to end): "); scanf("%f", &gallons); if(gallons == -1) break; counter = counter + 1; printf("Enter the miles driven:"); scanf("%f", &miles); counter1 = counter1 + 1; average = miles / gallons; printf("The miles / gallons for this tank was %f\n\n", average); counter++; } if(tgallons != 0) { taverage = tmiles / tgallons; printf("The overall average miles / gallons was %f\n", taverage); } return 0; }
