没法终止循环啊

这是结合前面几位修改的楼主试下
#include<stdio.h>
#include<math.h>
int main()
{
    float num ;
    int integer_num = -1;
     int   decimal_num = 0;
    while(num!=0)
    {
        scanf("%f", &num);
        if(fabs(num - (int)num) > 1e-4)
        {
            decimal_num=decimal_num+1;
        }
        else
            integer_num=integer_num+1;
   
    }
    printf("the integer_num is %d\n", integer_num);
    printf("the decimal_num is %d\n", decimal_num);

    return 0;
}

#include<stdio.h>
#include<math.h>
int main()
{
    double num;              
    int integer_num = 0,
        decimal_num = 0;
    scanf("%lf", &num);       //这里要用"%lf"

    while(num!=0)   //
    {   
        if(fabs(num - (int)num) > 1e-4)
        {
            //integer_num=integer_num+1;
            decimal_num=decimal_num+1;
        }
        else
            integer_num=integer_num+1;
    scanf("%lf", &num);
   }
printf("the integer_num is %d\n", integer_num);
printf("the decimal_num is %d\n", decimal_num);

return(0);
}

你这可以了

新手，没法注意那么多啦！fabs(num - (int)num) > 1e-4，为什么后面是—4？如果输入个1.0怎么办啊，算到整数里面去了

不过输入个1.0就加到整数里去了。。。。。。纠结
