我不能完全弄清楚這個while循環。我瞭解這個概念,我只是不知道該怎麼增加它。另外,由於某種原因,我的跑步總數不起作用?while循環不起作用,如果沒有更改終止它
這背後的想法是設置一個錢儲存在一個罐子的目標。每次我在罐子裏放入一定數量的金錢時,我都希望它能給我罐子裏的所有金錢,並告訴我需要多少錢才能放入罐子才能達到我的目標。
這裏是我的代碼:
#include <stdio.h>
int main() {
int goal;
int total = 0;
int deposite;
int ammountNeeded;
printf("How much money would you like to save?\n ");
scanf("%i", &goal);
printf("How much money are you putting in the jar?\n");
scanf("i%", &deposite);
total = total + deposite;
ammountNeeded = goal - deposite;
while (goal > total) {
printf("How much money are you putting in the jar?\n ");
scanf("i%", &deposite);
printf("You have saved R%i. ", total);
printf("You need to save another R%i in order to reach your goal.\n ",ammountNeeded);
}
if (total >= goal) {
printf("Well done! you have sucsessfully saved R%i", goal);
}
return 0;
}
此代碼既不是C#,目標C,或C++。只應用實際有效的標籤。 –
您需要將'deposite'添加到'total'並將其存回'total',否則值永遠不會改變,循環也不會退出,正如您所觀察的那樣。 – aglasser
我看到幾個拼寫錯誤。我沒有看到'while'循環內'total'或'ammountNeeded' [sic]的調整。切勿使用'scanf'。 – zwol
