想对下结果，确保正确

#include<stdio.h>

int main(void)
{
    /*int a=7;
    float x=2.5;
    float y=4.7;
    printf("%f",x+a%3*(int)(x+y)%2/4);*/  //2.5
    
    /*int b=7;
    float a=2.5,c=4.7;
    printf("%f",a+(int)(b/3*(int)(a+c)/2)%4);*/ //5.5
    
    /*int a=2,b=3;
    float x=3.5,y=2.5;
    printf("%f",(float)(a+b)/2+(int)x%(int)y);*/  //3.5
    
    int x=3,y=2;
    float a=2.5,b=3.5;
    printf("%d",(x+y)%2+(int)a/(int)b); //1
    
}
