问题 填空题

有以下语句段
int n1=10，n2=20；
printf(" 【7】 "，n1，n2)；
要求按以下格式输出n1和n2的值，每个输出行从第一列开始，请填空。
n1=10
n2=20

答案

参考答案：n1=%d\nn2=%d\n或n1=%d\nn2=%d或n1=%2d\nn2=%2d\n或n1=%2d\nn2=%2d

解析： printf函数有两种参数，格式控制参数和输出项参数。其中格式控制参数由两种成分组成：格式说明和普通字符，普通字符将被简单地复制显示，格式说明项将引起一个输出参数项的转换与显示，它是由%引出并以一个类型描述符结束的字符串。本题中，n1=和n2=就是普通字符，可以直接输出，因为n1，n2为整数，所以格式说明项为%d，在每行输出结束时加转义字符\n进行换行。
