c - Is it possible to make an action that does line number "x" -


Let me explain myself, I do not know that this is possible, so I will write it in the phonetic code 

  while (position) {line number acts in x; X ++; }

For example, if my code has the following line in line number 40: "printf (" hello ");" The program will print "Hello" and then check the status and if the situation is correct then it will take action in line number 41.

Instead of thinking of going / x line, perform and come back < / Code>, how do we create a group of some statements , to create some functions , call them one by one and do our job? feels good?

Ok, I give you an idea of ​​how to do this, you will write code. Agree? : -)

  1. Take the first requirement [at least 1 point]. Write a function, say int checkForDigit (const char * ip, int size) , which will examine all the elements of the array [[code up to ] and get it very moment One point, it will return to 0, otherwise, at the end, return 1.
  2. Take another requirement, [at least one small-case letter] Write a function, say int checkForSmallCase (const char * ip, int size) All the elements will check [[code up to
  3. Continue to add different functions for different verification requirements

Now, in your code,

  1. define a flag variable , And set it to a default value, maybe -1 .
  2. Take input of your password string , calculate size.
  3. Call the checkout function with password strings and length.
  4. Call each other valid work, one by one, and submit the return value in the flag.

Finally, if all validations are successful, the value of the flag will be 0 . Consider a valid password Otherwise, ask for a new password.
