Function 线程1：断点3.1？

为什么我的程序在那一点停止？我想创建一个函数来打印复利后的余额，但由于某些原因，它没有打印。。。这就是我所拥有的：

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

int printBalance(double initial, double interest, double years);
int main() {
    double initial, interest, i, years;
    printf("Enter initial deposit: ");
    scanf("%lf", &initial);
    printf("Enter percent interest rate: ");
    scanf("%lf", &interest);
    printf("Enter the number of years: ");
    scanf("%lf", &years);
    for (i = 0; i < years; i++) {
        printBalance(initial, interest, i);
    }
}

int printBalance(double initial, double interest, double years) {
    double  balance;
    balance = initial * (pow((1 + interest/100), years));
    printf("%lf", balance);
    return 0;
}

#包括

#包括
int打印余额（双首付、双利息、双年）；
int main（）{
双首字母，利息，i，年；
printf（“输入初始存款：”）；
scanf（“%lf”和首字母）；
printf（“输入利率百分比：”）；
scanf（“%lf”和利息）；
printf（“输入年份：”）；
scanf（“%lf”、&years）；
对于（i=0；i<年；i++）{
打印余额（初始、利息、i）；
}
}
整数打印余额（双倍首付、双倍利息、双年度）{
双平衡；
余额=初始*（pow（（1+利息/100），年）；
printf（“%lf”，余额）；
返回0；
}

考虑以下几点

/* This program calculates the balance after compound interest. The user is
 * prompted to enter an initial amount, percent interest, and a number of
 * years. This program outputs the year number, principal amount at the
 * start of that year, the amount compounded, and the balance after the
 * compounding. */
