浮点数用成了float

样例

#include<stdio.h>
int main()
{
    double x;
    scanf("%lf",&x);
    if(x>=0&&x<=25)
        printf("Intervalo [0,25]");
    else if(x>25&&x<=50)
        printf("Intervalo (25,50]");
    else if(x>50&&x<=75)
        printf("Intervalo (50,75]");
    else if(x>75&&x<=100)
        printf("Intervalo (75,100]");
    else if(x<0||x>100)
        printf("Fora de intervalo");
    return 0;
}
