Thread: How to duplicating the Array & copy tokenPtr to an array

Dear fellows, I have few questions here.

(1) Duplicating the Array
This is part of my code for duplicating the array from
name[j] to secondname[x]

Code:

            // Read from a file entered by user          while(fgets( name[j], 255, fpPtr )!=NULL){    
                printf( "Name %s\n", name[j] );                // Verfication
                strcpy( name[j], secondname[x] );    
                printf( "Second name %s\n", secondname[x] );    // Verification
                j++;
                x++;
            }

When I run the program, how comethe string for secondname[x] does not contain any value inside?


(2) Copy tokenPtr to an array

In the followings function prototype, I want to copy the string contain inside the token pointer to an array named tempsort[x], but this process was not success when I use the strcpy method, kindly show me the correct way of dealing with token pointer in the strtok.

Code:

void namesort ( char name[LEN][SIZE], int last ){       int  i, j, x;         // indices of array
    char *tokenPtr;    // create char pointer;
    char tempsort[LEN][SIZE];


    for (i = last ; i > 0 ; i--){


        for (j = 0 ; j <= last ; j++){
            printf("sorting %s",name[j]);    // For checking
              for (x = 0 ; x <= last ; x++){
                tokenPtr = strtok (name[j], ".");
                while (tokenPtr != NULL){
                    printf("tokenPtr: %s\n", tokenPtr) ;    // For checking                
                    strcpy( tokenPtr,tempsort[x] );            // assint tokenPtr to tempsort
                    printf("tempsort: %s\n", tempsort[x]) ;    // For checking                            
                    tokenPtr = strtok ( NULL, ".");            // get next token    
                }    // end while
//                    printf("%s",name[j]) ;    // For checking
            }
        }
    }
}     // End function prototype

Thanks in advance
