ctrl+向右的箭头。采用将文字转换为表格的方式来实现。先选中要转换为表格的文字,表格-转换-文字转换为表格-文字分隔位置选择为段落标记,列数选择为2列,行数自动即可。 (推荐学习:web前端视频教程)
转换为表格后,第一列是英文,第二列是相应的中文,然后把表格框线设置成无即可。相当于分成两栏了。

函数返回值
成功则不返回值, 失败返回-1, 失败原因存于errno中,可通过perror()打印
Windows下示例(vs编译):
#include <stdio.h> #include <process.h> int main() { printf("调用D盘Test目录下的hello.exe, 第一个参数为该应用程序的名称\n"); execl("D:\\Test\\hello.exe","hello"); printf("进程已经被递交给了hello.exe,这里不会再执行"); }
Linux下示例:
示例1
/* 执行 /bin/ls -al /ect/passwd */ #include <unistd.h>/*** File: execl.c**/ main() { // 执行/bin目录下的ls, 第一参数为程序名ls, 第二个参数为"-al", 第三个参数为"/etc/passwd" execl("/bin/ls", "ls", "-al", "/etc/passwd", (char *) 0); }
示例2
#include <unistd.h>/*** File: execl.c**/ int main() { char args[]=" -l"; // 执行/bin目录下的ls, 第一参数为程序名ls, 第二个参数为"-al", 第三个参数为"/etc/" execl("/bin/ls","ls","-al","/etc/",NULL); return 0; }
编译并运行
[cnscn@test c]$ gcc execl.c -o execl [cnscn@test c]$ ./execl -rw-r--r-- 1 root root 2218 Jan 13 11:36 /etc/passwd
