这一工程由级联数比较.只要其中一则真实结果,声明如下块或签 并没有进一步进行比较.在以下例子,我们靠授职考试结果.
if (result <=100 && result >= 75)
printf("Passed: Grade A\n");
else if (result >= 60)
printf("Passed: Grade B\n");
else if (result >= 45)
printf("Passed: Grade C\n");
else
printf("Failed\n");
这个例子,都称为变单一测试比较结果.在其他情况下,每一个不同的测试可能涉及一些变数或组合测试.同样的模式可以用更多或者更少,如果其他的,最后,仅剩下5人.
这对程序员的正确结构设计每个节目的问题.如果了解使用的例子一样,让我们看看
#include <stdio.h>
int main()
{
int num;
for(num = 0 ; num < 10 ; num = num + 1)
{
if (num == 2)
printf("num is now equal to %d\n", num);
if (num < 5)
printf("num is now %d, which is less than 5\n",
num);
else
printf("num is now %d, which is greater than 4\n",
num);
} /* end of for loop */
return 0;
}
由于节目
num is now 0, which is less than 5
num is now 1, which is less than 5
num is now equal to 2
num is now 2, which is less than 5
num is now 3, which is less than 5
num is now 4, which is less than 5
num is now 5, which is greater than 4
num is now 6, which is greater than 4
num is now 7, which is greater than 4
num is now 8, which is greater than 4
num is now 9, which is greater than 4 |
