What is the output of the following C Code??

#includestdio.h
void main(){
 int a,b,c;
 printf("enter the value of a: ");
 scanf("%d",&a);
 printf("enter the value of b: ");
 scanf("%d",&b);
 printf("enter the value of c: ");
 scanf("%d",&c);
 if(a=b && a=c)
  printf(" a = %d is smallest",a);
 if(b=a && b=c)
  printf("b = %d is smallest",b);
 if(c=a && c=b)
  printf("c = %d is smallest",c);
}

If entered value is 4,5,8
