Problem 2.3 How Many Weeks?
General Statement: A town in Death Valley has a water tank that contains 10,000 gallons of water. If there is no rain, calculate the number of weeks the water will last for an input weekly water usage.
Input: The data set is on a single line. There are an unknown number of integers in the data set. The integer 0 is used to indicate the end of the data.
Output: Use all upper case letters. The output is to be formatted exactly like that for the sample output given below.
Assumptions: The weekly usage does not exceed 10,000 gallons. The 0 used to indicate the end of the data is not part of the data for the problem.
Discussion: Do not include the last week if the water remaining for that week is less than the weekly usage amount.
Sample Input: 1750 1000 4325 0
Sample Output:
1750 GALLONS PER WEEK WILL LAST 5 WEEKS
1000 GALLONS PER WEEK WILL LAST 10 WEEKS
4325 GALLONS PER WEEK WILL LAST 2 WEEKS
Solutions:
#include <stdio.h>
int main ()
{
int water_usage;
while ( scanf ("%d", &water_usage) && water_usage ) {
printf ("%d GALLONS PER WEEK WILL LAST %d WEEKS\n", water_usage, 10000 / water_usage );
}
return 0;
}
#include
int main(){
int weekly_usage;
int i,x;
int duration=0;
printf(“please enter the number of inputs: “);
scanf(“%d”,&x);
printf(“\n”);
for(i=1;i<=x;i++){
duration=0;
printf("please enter the weekly usage: ");
scanf("%d",&weekly_usage);
printf("\n");
printf("the number of weeks for this weekly usage is: %d\n",duration=10000/weekly_usage);
printf("\n");
}
return 0;
}
