求输入两个数的和、差、积、商和余数（如果是浮点数，则需将其强转为整型后计算余数）。

求输入两个数的和、差、积、商和余数（如果是浮点数，则需将其强转为整型后计算余数）。请改正程序中的错误，使它能得出正确的结果。
#include 

main()
{
    float a, b;
    float sum, minus, product, quotient;
    int remainder;

    printf("n请输入两个数:n");
    scanf("%fn%f", a, &b);
    sum = a + b;
    minus = a - b;
    product = a * b;
    quotient = a / b;
    remainder = a % b;
    printf("和为:%.2fn", sum);
    printf("差为:%.2fn", minus);
    printf("积为:%.2fn", product);
    printf("商为:%.2fn", quotient);
    printf("余数为:%dn", remainder);
