C语言笔记-字符串+转义符(写起来想砸键盘)

Posted 2020-07-03

转义符真心写起来好麻烦...

代码:

 1 #include <stdio.h>
 2 int main()
 3 {
 4     printf("sizeof(\"123\")      =%u\n",(unsigned)sizeof("123"));
 5     //结果的"在字符串字面量里要写成\"
 6     printf("sizeof(\"AB\\tC\")    =%u\n",(unsigned)sizeof("AB\tC"));
 7     //结果的\要在字符串字面量里写成\\        Orz
 8     printf("sizeof(\"abc\\0def\") =%u\n",(unsigned)sizeof("abc\0def"));
 9     return 0;
10 }

结果:

sizeof("123")      =4
sizeof("AB\tC")    =5
sizeof("abc\0def") =8
