strcmp, look it up.
its in string.h
vous pouvez declarer une chaine de caractere dans un tableau de la facon suivante
#define max 10000
char t[max];
puis lire de cette facon
scanf("%c",&t[]);
la comparaison sera faite dans une boucle repeter caractere par caractere
je croit que ca c'est tre facile alors faite le vite
Hello raiden,
I also recommend strcmp(), let me write an example:
Code 1.1: Example of using strcmp()Code:#include <string.h> #include <stdlib.h> int main() { char *s1 = "Hello"; char *s2 = "Hello!"; char *s2 = "Hello"; if( !strcmp(s1, s2) ) printf("Match!"); else printf("Strings did not match"); if( strcmp(s1, s3) == 0 ) // used ! last time to indicate 0 printf("Match!"); else printf("Strings did not match"); return 0; }
What I did here was make three variables, *s1, *s2, and *s3. s1 and s3 are the same, while s2 varies from the group. strcmp returns 0 if the strings match, else > 1 depending on the difference of the two strings.
It's quite a simple implementation, so either way you use it "== 0" or "!" (which indicates 0) will still produce the same result. I personally like the "!" myself, but every programmer has his/her ways of coding format and style.
Hope this helped,

Segmentation Fault: I am an error in which a running program attempts to access memory not allocated to it and core dumps with a segmentation violation error. This is often caused by improper usage of pointers, attempts to access a non-existent or read-only physical memory address, re-use of memory if freed within the same scope, de-referencing a null pointer, or (in C) inadvertently using a non-pointer variable as a pointer.
