逗号操作

逗号经常采用丙作为一个简单标点符号、分隔变量声明,函数论调 等等,在某些情况下,作为一个逗号算.

你可以分开两个小组的形式表达了同一个逗号表达式.结果如下:

  • 双方表达了评价,表达与被评审一次离开.
  • 整个上课的表达权值表达. 例如,以下声明高度价值二至十,然后一递增,递增,然后乙:
    x = (a++, b++);

()是经营功能;[]是数组操作.

 

举个例子,使用操作:

/* 操作使用 */

int main()
{
int x = 0, y = 2, z = 1025;
float a = 0.0, b = 3.14159, c = -37.234;

/* 递增*/

x = x + 1; /* 这十大递增 */
x++; /* 这十大递增 */
++x; /* 这十大递增 */
z = y++; /* z = 2, y = 3 */
z = ++y; /* z = 4, y = 4 */

/* 西元 */

y = y - 1; /* 这个减薪肽Y */
y--; /* 这个减薪肽Y */
--y; /* 这个减薪肽Y */
y = 3;
z = y--; /* z = 3, y = 2 */
z = --y; /* z = 1, y = 1 */

/* 算术作品 */

a = a + 12; /* This adds 12 to a */
a += 12; /* This adds 12 more to a */
a *= 3.2; /* This multiplies a by 3.2 */
a -= b; /* This subtracts b from a */
a /= 10.0; /* 一本由10.0分 */


/* 有条件表达*/

a = (b >= 3.0 ? 2.0 : 10.5 ); /* 这表达 */

if (b >= 3.0) /* 这表达 */
a = 2.0; /* 是相同的,无论 */

else /* 同样会造成 */
a = 10.5; /* 结果. */

c = (a > b ? a : b); /* 三会一或二马克斯 */
c = (a > b ? b : a); /* 闵丙都有一个或二 */

printf("x=%d, y=%d, z= %d\n", x, y, z);
printf("a=%f, b=%f, c= %f", a, b, c);

return 0;
}

结果,这一计划将在屏幕上显示结果为:

x=3, y=1, z=1
a=2.000000, b=3.141590, c=2.000000
