打印到屏幕上的内容:

int main(void)
{
    int i, j;
    float p, q=6.2;

    int t[10];

    float *x;
    int *y;  
    x=&q;

    j=3;
    i=(int)q;
    i+=5;
    j=i--;
    printf("i=%d and j=%d\n", i, j);
//_____________i=10 and j=11__________________________   

    j=15;
    i=11;
    i=j&i;
    j=i&&j;
    printf("i=%d and j=%d\n", i, j);

//_______i=11 and j=1__________________________________ 

    i=4;
    j=25;

    p=j/i*10+j%3-6;

    printf("p=%.2f\n",p);


//__________p=55.00_______________________________

   y=t;

   for(i=0;i<10;i++)
       t[i]=(i==2)?2:(i*2);

   y+=2;
   printf("the value is %d\n",*y);


//____________the value is 2_____________________________   

return 0;

my question is what is the i=j&i and j=i&&j means in part2?

我的问题是什么是i = j&i和j = i && j意味着在第2部分?

in part 3 answer is p=55.00, By I calculated is (25/2)*10+1-6=57, why i am wrong?

在第3部分答案是p = 55.00,由我计算是(25/2)* 10 + 1-6 = 57,为什么我错了?

in part 4 what is t[i]=(i==2)?2:(i*2); means?

在第4部分中,什么是t [i] =(i == 2)?2:(i * 2);手段?

Hello I answer your first question: & is a bitwise and is used to perform multiplication bitwise by ejeplo 6 & 6 equals 110 & 110 = 110 as it operates bit by bit, && is a logical and is commonly used in conditional statements example where we need two or more conditions are met simultaneously: if a is greater than 16 and less than 30 run the following code:

你好我回答你的第一个问题:&是一个按位,用于按顺序执行乘法,ejeplo 6和6等于110和110 = 110,因为它一点一点地操作,&&是一个逻辑,并且通常用于条件语句示例中我们需要同时满足两个或多个条件:如果a大于16且小于30,则运行以下代码:

int a = 20;
if (a> 16 && a <30) {
}
