Thread: String prob

is their any ay to compare strings rather than using the strcmp() fuction? If not, could somebody fully explain how it works? All I want to do is see if two strings are the same...

C++ has overloaded the == operator to allow for the comparison of strings. Ex:

if(string1 == string2)
{
//ect

Why don't you want to use strcmp?

strcmp compares two strings and returns a value of 0 if they are the same. In the following example, the loop will run so long as strcmp is not returning 0.

Code:

#include <stdio.h>
#include <string.h>

int main ()
{
  char Animal1[] = "dog";
  char AnimalInput[20];

  do {
     printf ("Guess what sort of pet I have? ");
     gets (AnimalInput);
       } while (strcmp (Animal1,AnimalInput) != 0); 

  printf ("You guessed right, I have a %s\n",Animal1);
  return 0;
}

Teach me for not realising I'm out of the "C" thread. Never mind, strcmp is still good to know

well you could make a function then,

use a pointer to the string, then you can compare it this way,


if(*ptr1 == *ptr2) // if the letter are the same,
{
// increment both pointers to check for the next letter
ptr1++;
ptr2++;
}

well you can do that 'while' the ptr is not pointing to nul,
