In the Series of C Beginner Projects source code list we are going create Contact Management System(CMS) with C. This CMS project is for adding extra features when you plan to save the contact of a person. With this C program, you will be able to perform operations like saving the contact information of a person including name, phone number, email, and address. There will be a list of all contacts that are stored in the contact file, you can edit the contact information of the person at any time or even delete the contact from your file if you want.
It can be considered similar to the phonebook or electronic diary where you store the contact details of others, but here you are using the c console for these features.
The data is stored in the file, including the contact information like name, address, and email, using file handling. You can get the source code for the project by clicking on the download option below the image
This project contains below modules
Let's start
Step 1: Create C console project in any IDE, I have used CodeBlock IDE.
Step 2: Add functionality to Add New Contact
fflush(stdin);
printf("To exit enter blank space in the name input\nName (Use identical):");
scanf("%[^\n]",&list.name);
if(stricmp(list.name,"")==0 || stricmp(list.name," ")==0)
break;
fflush(stdin);
printf("Phone:");
scanf("%ld",&list.ph);
fflush(stdin);
printf("address:");
scanf("%[^\n]",&list.add);
fflush(stdin);
printf("email address:");
gets(list.email);
printf("\n");
fwrite(&list,sizeof(list),1,fp);

List all Contacts:
for(i=97; i<=122; i=i+1) { fp=fopen("contact.dll","r"); fflush(stdin); found=0; while(fread(&list,sizeof(list),1,fp)==1) { if(list.name[0]==i || list.name[0]==i-32) { printf("\nName\t: %s\nPhone\t: %ld\nAddress\t: %s\nEmail\t: %s\n",list.name, list.ph,list.add,list.email); found++; } } if(found!=0) { printf("=========================================================== [%c]-(%d)\n\n",i-32,found); getch(); } fclose(fp); |
 |
Search Contact:
do { found=0; printf("\n\n\t..::CONTACT SEARCH\n\t===========================\n\t..::Name of contact to search: "); fflush(stdin); scanf("%[^\n]",&query); l=strlen(query); fp=fopen("contact.dll","r"); system("cls"); printf("\n\n..::Search result for '%s' \n===================================================\n",query); while(fread(&list,sizeof(list),1,fp)==1) { for(i=0; i<=l; i++) name[i]=list.name[i]; name[l]='\0'; if(stricmp(name,query)==0) { printf("\n..::Name\t: %s\n..::Phone\t: %ld\n..::Address\t: %s\n..::Email\t: %s\n",list.name,list.ph,list.add,list.email); found++; if (found%4==0) { printf("..::Press any key to continue..."); getch(); } } } if(found==0) printf("\n..::No match found!"); else printf("\n..::%d match(s) found!",found); fclose(fp); printf("\n ..::Try again?\n\n\t[1] Yes\t\t[0] No\n\t"); scanf("%d",&ch); } while(ch==1); |

Edit Contact:
fp=fopen("contact.dll","r"); ft=fopen("temp.dat","w"); fflush(stdin); printf("..::Edit contact\n===============================\n\n\t..::Enter the name of contact to edit:"); scanf("%[^\n]",name); while(fread(&list,sizeof(list),1,fp)==1) { if(stricmp(name,list.name)!=0) fwrite(&list,sizeof(list),1,ft); } fflush(stdin); printf("\n\n..::Editing '%s'\n\n",name); printf("..::Name(Use identical):"); scanf("%[^\n]",&list.name); fflush(stdin); printf("..::Phone:"); scanf("%ld",&list.ph); fflush(stdin); printf("..::address:"); scanf("%[^\n]",&list.add); fflush(stdin); printf("..::email address:"); gets(list.email); printf("\n"); fwrite(&list,sizeof(list),1,ft); fclose(fp); fclose(ft); remove("contact.dll"); rename("temp.dat","contact.dll"); |
Delete Contact
system("cls"); fflush(stdin); printf("\n\n\t..::DELETE A CONTACT\n\t==========================\n\t..::Enter the name of contact to delete:"); scanf("%[^\n]",&name); fp=fopen("contact.dll","r"); ft=fopen("temp.dat","w"); while(fread(&list,sizeof(list),1,fp)!=0) if (stricmp(name,list.name)!=0) fwrite(&list,sizeof(list),1,ft); fclose(fp); fclose(ft); remove("contact.dll"); rename("temp.dat","contact.dll"); |
