c - If Else 在 While 循环中

Question

我在使用这段代码时遇到了问题。当我运行它时，它只打印出 while 语句中的两行。我试图让它运行 if 语句，直到 MortgageLeft

有人可以看到我犯的错误吗？我不知道这是否有帮助，但如果我删除 else 语句，程序运行正常

#include <stdio.h>
#include <stdlib.h>

int main(){
    float MortgageLeft, InterestRate, MonthlyPayment, MonIntRate, AmountOwed;
    int Month=0;

    printf("What is the value left on the mortgage?\n");
    scanf("%f", &MortgageLeft);

    printf("What is the annual interest rate of the loan, in percent?\n");
    scanf("%f", &InterestRate);

    printf("What is the monthly payment?\n");
    scanf("%f", &MonthlyPayment);

    MonIntRate= (InterestRate/12)/100;

    printf("Month\t\t Payment\t Amount Owed\n");

    while (MortgageLeft>0)
    {
        if(MortgageLeft>MonthlyPayment)
        {
            MortgageLeft=(MortgageLeft*MonIntRate)+MortgageLeft;
            MortgageLeft=MortgageLeft-MonthlyPayment;    
            Month++;
            printf("%d\t\t %.2f\t\t %.2f\n", Month, MonthlyPayment, MortgageLeft);
        }
        else
            MortgageLeft=(MortgageLeft*MonIntRate)+MortgageLeft;
        Month++;
        printf("%d\t\t %.2f\t 0", Month, MortgageLeft);
        MortgageLeft=0;
    }
    return 0;
}

您似乎缺少一些括号

while (MortgageLeft>0)
    {
        if(MortgageLeft>MonthlyPayment)
        {
        MortgageLeft=(MortgageLeft*MonIntRate)+MortgageLeft;
        MortgageLeft=MortgageLeft-MonthlyPayment;    
        Month++;
        printf("%d\t\t %.2f\t\t %.2f\n", Month, MonthlyPayment, MortgageLeft);
        }
        else
        {
        MortgageLeft=(MortgageLeft*MonIntRate)+MortgageLeft;
        Month++;
        printf("%d\t\t %.2f\t 0", Month, MortgageLeft);
        MortgageLeft=0;
        }
   }
