1.通过试验（即编写带有此类问题的程序）观察系统如何处理整数上 溢、浮点数上溢和浮点数下溢的情况。 #include<stdio.h> int main (void) { int z1; float f1,f2; z1=-2147483647; f1=3.4E38; f2=-3.4E38; printf("%d,%d,%d",z1,z1-1,z1-2); printf("%f,%f,%f",f1,f1*10); printf("%f,%f",f2,f2/10); return 0; } 2.编写一个程序，发出一声警报，然后打印下面的文本：Startled　by　the　sudden　sound,　Sally　shouted,"By　the　Great　Pumpkin,　what　was　that!" #include<stdio.h> int main() { printf("\a"); printf("Startled　by　the　sudden　sound,　Sally　shouted,\n"); printf("\"By　the　Great　Pumpkin,　what　was　that!\"\n"); return 0; } 3.编写一个程序，读取一个浮点数，先打印成小数点形式，再打印成指 数形式。然后，如果系统支持，再打印成p记数法（即十六进制记数法）。 按以下格式输出

从一个utf8的postgres抽到另一个utf8的postgres里，中间除了一步python的数据脱敏，其余都是kettle流程，排查发现，数据从进入kettle开始就是乱码了， 还没有经过python的步骤，所以锁定在kettle的问题。通过修改kettle的启动文件Spoon.bat来解决之。 if "%PENTAHO_DI_JAVA_OPTIONS%"=="" set PENTAHO_DI_JAVA_OPTIONS="-Xms128m" "-Xmx4096m" "-XX:MaxPermSize=256m" 用notpad++右键打开Spoon.bat，找到上边的这句话，在他后边添加指定编码即可。 if "%PENTAHO_DI_JAVA_OPTIONS%"=="" set PENTAHO_DI_JAVA_OPTIONS="-Xms128m" "-Xmx4096m" "-XX:MaxPermSize=256m" "-Dfile.encoding=UTF8" 重启kettle解决之。 参考： https://forums.pentaho.com/threads/94865-encoding-problem-utf8/ 来源： oschina 链接： https://my.oschina.net/finchxu/blog/4503451
