如何打印转义字符的字符？ [英] How do i print escape characters as characters?

问题描述

我想打印转义字符作为使用该code字符或字符串：

I'm trying to print escape characters as characters or strings using this code:

while((c = fgetc(fp))!= EOF)
{
    if(c == '\0')
    {
        printf("   \0");
    }
    else if(c == '\a')
    {
        printf("   \a");
    }
    else if(c == '\b')
    {
        printf("   \b");
    }
    else if(c == '\f')
    {
        printf("   \f");
    }
    else if(c == '\n')
    {
        printf("   \n");
    }
    else if(c == '\r')
    {
        printf("   \r");
    }
    else if(c == '\t')
    {
        printf("   \t");
    }
    else if(c == '\v')
    {
        printf("   \v");
    }
}

但是当我尝试它，它实际打印的转义序列。

but when i try it, it actually prints the escape sequence.

推荐答案

逃离斜杠（使用\\\\一个），所以他们不会得到跨$ P $特别PTED。您可能还需要使用一个查找表或开关至少

Escape the slashes (use " \\a") so they won't get interpreted specially. Also you might want to use a lookup table or a switch at least.

switch (c) {
case '\0':
    printf("   \\0");
    break;
case '\a':
    printf("   \\a");
    break;
/* And so on. */
}
