c - 如果其他没有运行

Question

我修复了你们指出的问题(谢谢顺便说一句!)，但现在它给了我一个无限循环。我不明白为什么。每次 while 循环运行时，我的抵押贷款余额都会随着每月还款额而减少...

#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\n");
    scanf("%f", &MonthlyPayment);

    MonIntRate= (InterestRate/12)/100;

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

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

}
    return 0;
}

您的 while 循环缺少任何括号，因此它仅执行循环中的下一条语句 AmountOwed=(MortgageLeft*MonIntRate)+MortgageLeft;，该语句永远不会更改循环条件。无限循环意味着您永远不会到达 if/else。
