This is an unfinished file name immigration.c
This is modifyImmigration.cCode:#include <stdio.h> #include <string.h> #include <stdlib.h> #include "structure.h" #include "modifyImmigration.h" int main(int argc,char* argv[]) { int status = 0; char buffer[64]; char codeString[64]; DATA_T person[100]; int check; char *newValue; int index; int modify; while(status != 6) { printf("\n\t\t =========================================\n"); printf("\n\t\t\tWelcome to Immigration Database!!\n\n"); printf("\t\t =========================================\n"); printf("\t\t\t Choose what you want to do:\n"); printf("\t\t =========================================\n\n"); printf("\t\t\t 1)Display all records\n"); printf("\t\t\t 2)Search an existing record\n"); printf("\t\t\t 3)Add a new record\n"); printf("\t\t\t 4)Modify an existing record\n"); printf("\t\t\t 5)Delete an existing record\n"); printf("\t\t\t 6)Exit the program\n"); printf("\n\t\t =========================================\n"); printf("\n\t\t Press 1,2,3,4,5 or 6: "); fgets(buffer,64,stdin); sscanf(buffer,"%d",&status); if(status == 1) { } else if(status == 2) { } else if(status == 3) { } else if(status == 4) { Edit(argc, argv, newValue, index, modify, person); } else if(status == 5) { } else if(status == 6) { printf("\n\n\t\t ========================================="); printf("\n\t\t Thank you for using our program :)"); printf("\n\t\t ========================================="); exit(0); } else { printf("\nError!

This is modifyImmigration.hCode:#include <stdio.h> #include <string.h> #include <stdlib.h> #include "structure.h" void Edit(int argc, char* argv[], char *newValue, int index, int modify, DATA_T person[100]) { char* inputFile; /*Pointer inputFile*/ char* outputFile; /*Pointer outputFile*/ char inputBuffer[128]; int i = 0; int j = 0; int line = 0; FILE* pInfile = NULL; /*Set pInfile to be NULL*/ FILE* pOutfile = NULL; /*Set pOutfile to be NULL*/ /*Copy files from arguement array to local variables*/ inputFile = strdup(argv[1]); outputFile = strdup(argv[1]); /*Check arguement to make sure that we have the right number.

and this is structure.hCode:void Edit(int argc, char* argv[], char *newValue, int index, int modify, DATA_T person[100]);
Why is there an error: undefine reference to '_Edit'Code:typedef struct { char passportID[16]; /* Passport ID of the user */ char firstName[30]; /* First name of the user */ char lastName[30]; /* Last name of the user */ char expireDate[10]; /* Expiration date of the passport */ char entryDate[10]; /* Date of last entry into Thailand */ char exitDate[10]; /* Date of last exit from Thailand */ char visaType[30]; /* Type of visa */ } DATA_T;
Thank you for your help
