C语言笔记-字符串+转义符(写起来想砸键盘)

转义符真心写起来好麻烦...

代码:

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

结果:

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