c - Xcode5与C失去连接错误

Question

当我构建并运行我的代码时，我得到了这个错误

one exited unexpectedly lost connection

Program ended with exit code; -1

有什么想法吗？

#include <stdio.h>

int main()
{
    int hour;
    float price, total_price;
    char first_letter;
    printf("Type first letter of worker name> ");
    scanf("%c",&first_letter);
    printf("Type work hours> ");
    scanf("%d",&hour);
    printf("Type price for per hour> ");
    scanf("%f",&price);
    total_price = hour * price;
    printf("%c worker will get money per hour: %f\n",first_letter,total_price);
    return 0;
}

我遇到了完全相同的问题。使用 shift+Enter，没有 shift 就是回车。
