有以下程序：
#include＜stdio.h＞
#define f(x) (x*x)
main()
int i1, i2;
i1=f(8) /f(4);
i2=f(4+4) /f(2+2);
printf("%d, %d\n", i1, i2);
程序运行后的输出结果是( )。
A) 64, 28
B) 4, 4
C) 4, 3
D) 64, 64
参考答案：C
解析： 本题考查的是带参数的宏。宏替换与函数调用不同，前者是字面上的，在编译期间完成，后者是内容上的，在运行期间才进行。题目中第1条要替换的语句i1=f(8)/f(4)；展开后是i1=(8*8)/(4*4); ，结果使i1=4。而第2条语句i2=f(4+4)/f(2+2)；展开后为i2=(4+4*4+4)/(2+2*2+2); ，结果使i2=24/8=3。故应该选择C)。

| This week we asked students at New Star High School about the best ways to learn more English. Mary said they learnt by using English. Some students had more specific suggestions. Bruce Li, for example, said the best way to learn new words was by reading English magazines. He said that memorizing the words of pop songs also helped a little. When we asked about studying grammar, he said, "I have never studied grammar. It's too boring." Wei Ming feels differently. He has been learning English for six years and loves it a lot. He thinks studying grammar is a great way to learn a language. He also thinks that watching English movies isn't a bad way because he can watch the actors say the words. Liu Chang said that joining the English club at school was the best way to improve her English. Students get lots of practice and they also have fun.
