}

Why is the typing errors?

This is not done well

?? Why the typing errors

CodePudding user response:

Unsigned char class to unsigned char clazz [256].
Pay attention to the difference between characters and strings, other detail and date is the same problem
In addition, the class the keyword as far as possible not to used for variable

Thank you print it out or not, however, whether the printf to write the wrong

CodePudding user response:

Printf (" % % c c % % 1 f c ") % c to print a single character, % s print string

print string

Bosses I finished there was a mistake to help me have a look at it in a for loop should be the string in the judgment of the if function?

If (num [m]. Clazz=="income") this is to use STRNCMP string comparison function, if a different prompt, change their type or the strong around

CodePudding user response:

If (num [m]. Clazz=="income")==="" the if (STRCMP (num [m]. Clazz," income ")==0)
