main()

{ double d=3.2; int x,y;

 x=1.2; y=(x+3.8)/5.0;

 printf("%d\n",d*y);

}

程序的输出结果是

 int a = 20;

   int b = 3;

   printf(“%d\n,”a+=(b%=2));

y=8; y+= y–=y*y;

main()

{ int a=1,b=2;

 a=a+b; b=a-b; a=a-b;

 printf("%d,%d\n",a,b);

}

printf("%d",sizeof(a*b)+2/5);

  x = a++;y= --a;z=x+y-a--;

x=5; y=x++*x++; y=--y*--y;

main()

{  int x,y,z;

 x=y=1;

 z=x++,y++,++y;

 printf("%d,%d,%d\n",x,y,z);

}

程序运行后的输出结果是

main()

{ int x=4,y=7;

 x-=y;

 y+=x;

 printf("%d %d\n",x,y);

}

main()

{ int i=10,j=1;

i=i+j++;

 printf("%d,%d,%d\n",i++,++j,i); }

执行后输出结果是
