c - C 编程 printf、scanf

Question

嗨，我已经编写了这段代码，但输出如下：

你旅行了多少英里？：（你显示的次数）
你消耗了多少加仑汽油？：

然后它只是跳过扫描并移动到下一个位置，

#include <stdio.h>
#include <string.h>
#include <float.h>

int main ()
{

    float mile;
    float gallon;

    printf("How many Miles have u traveled?: ");
    scanf("%.1f",&mile);
    printf("How many gallons of gasoline have u consumed?: ");
    scanf("%.1f",&gallon);

} 

Answer 1

您不应该格式化输入。所以只需%f用作的第一个参数scanf

int main ()
{

    float mile;
    float gallon;

    printf("How many Miles have u traveled?: ");
    scanf("%f",&mile);
    printf("How many gallons of gasoline have u consumed?: ");
    scanf("%f",&gallon);

}
