想在printf中,输出多行数据,如果写成下面这样: printf("line 1\n line 2\n line 3\n");编译器会报错“error C2001: newline in constant”. 可以这样写: printf("line 1\ line 2\ line 3\n"); 或者 printf("line 1" "line 2" "line 3\n");
使用STM8L052输出调试信息 重定向put char #include "stdio.h" //必不可缺少 char putchar (char c) { /* Write a character to the USART */ USART_SendData8(USART1, c); /* Loop until the end of transmission */ while (USART_GetFlagStatus(USART1, USART_FLAG_TC) == RESET)
1063 Set Similarity (25 分) Given two sets of integers, the similarity of the sets is defined to be /, where Nc is the number of distinct common numbers shared by the two sets, and Nt is the total number of distinct numbers in the two sets. Yo
直接描述吧:int i = 0;while(1){printf("now i = %d\r", i);fflush(stdout);i++;sleep(1);}我想在输出中不仅仅是显示最后一行,怎么改写这个代码?我想要有好几行同时在更新输出.比如同时输出多个printf的更新:now i = 0now i = 0now i = 0...这种类型,而不是文中代码里那样,只有一行输出是更新的. 已经解决,答案在5楼.呵呵 附件: 文件注释: 这个是图片 参考资料: http://forum
declare @num1 int --为符合条件的总行数 select @num1=COUNT(1) from cardInfo where openDate between @date1 and @date2 --@date1 和 @date2 为开始时间到结束时间,可以理解一个条件 while(@num1<>0) --和下面的set@num1-=1形成循环的次数begin print @num1 --循环输出@num1的值,
