checking last char of string in c
提问by radar75
If I have two types of strings as:
如果我有两种类型的字符串：
const char *str1 = "This is a string with \"quotes escaped at the end\"";
const char *str2 = "This is a \"string\" without quotes at the end";
testFn(str1);
testFn(str2);
int testFn(const char *str)
{
// test & return 1 if ends on no quote
// test & return 0 if ends on quote
return;
}
I would like to test if the string ends with a quote " or not
我想测试字符串是否以引号 " 结尾
What would be a good way of testing this? Thanks
什么是测试这个的好方法？谢谢

Don't forget to make sure your string has at least 1 character:
不要忘记确保您的字符串至少有 1 个字符：
int testFn(const char *str)
{
return (str && *str && str[strlen(str) - 1] == '"') ? 0 : 1;
}

return !str || !*str || str[strlen(str) - 1] != '\"';
}
