Thread: nested while loop

Hi I'm doing a program that ask a User to enter a sentence, then the program will look for the same words on the sentence from declared array of words.

Code:

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

int main()
    {
    char string[100];
    char word[100];
    int i,namecount=0;
    char *result;
    char delims[] = "  \n";
    char *array[] = {"one", "two", "three", "four"}; 
    int x;
    printf("Type a string : ");
    fgets(string,100,stdin);
    result = strtok( string, delims );
        while( result != NULL ) {
            strcpy(word, result);
            printf( "result is: %s\n", word );
        for( x = 0; array[ x ] != NULL; x++ ){    
        if ( strcmp ( word, array[x]) == 0 ) 
                printf( "The Same!.\n" );
            }
            
            
        result = strtok( NULL, delims );
    }
    
}

OUTPUT:
Type a String: four three
result is: four
The Same!
Segmentation fault

I need to loop it but I can't figure it out! Please help!

Your seg fault lies in line 21.

Code:

array[ x ] != NULL;

You need to change it or add NULL to your **array.

yey Thank you so much
