Electric Power Supply Complaint Registration Menu Driven Program using C language

Here, in this program, we are creating a menu-driven program with the help of C language for the complaint registration under the electric power supply office.

Filename:- powersupply.c

#include<stdio.h>

#include<string.h> //including string header file for string functions

#include<math.h>

int menu()

{

 int press; //variable to take user input

 puts("Press 1 for Report Supply Off"); //menu choices

 puts("Press 2 for Register a Complaint");

 puts("Press 3 for New Connection Installation");

 puts("Press 4 for Low Voltage Fluctuations");

 puts("Press 5 for Register Electricity Theft");

 puts("Press 6 for Book a Visit to the Supply Office");

 scanf("%d",&press); //receiving value from user

 return press; //returning the user inputted value to the main function

}

void supplyoff() //supplyoff function definition

{

    int offtime;

    char lightpost[30];

    puts("How much time the supply is off?\n");

    puts("Press 1 for less than 1 hour");

    puts("Press 2 for more than 1 hour");

    scanf("%d",&offtime);

    if(offtime==1)

        puts("Your complaint is registered, the supply will be restored soon.");

    else if(offtime==2)

    {

        puts("Enter your nearest lightpost number:");

        scanf("%s",lightpost); //receiving lightpost number

        printf("Our executive is on the way to your area %s for recovery.\n", lightpost);

    }

    else

        puts("Sorry, invalid input!");

}

void regcomp() //regcomp function definition

{

    int phone[10];

    puts("May I know your Mobile Number:\n");

    scanf("%d",phone); //taking user's phone number

    printf("Your complaint is registered. Our technician will call you recently.\n");

}

void newconn() //newconn function definition for new connection

{

    char addr[50];

    puts("May I know your address:\n");

    scanf("%s",addr); //taking the address from user

    printf("Our executive will visit your address soon for the new connection.\n");

}

void bookvisit()

{

    printf("Your booking number is %d\n",rand()); //printing a random number for the booking

    puts("Please visit next week after 11.30am\n");

}

void voltf()

{

    char lightpost[30];

    puts("Enter your nearest lightpost number:");

    scanf("%s",lightpost);

    printf("Your complaint number is %d\n",rand());

    puts("Our experts will visit your area soon.\n");

}

void etheft()

{

    char addr[50];

    puts("May I know your address:\n");

    scanf("%s",addr);

    printf("Your complaint number is %d\n",rand());

    puts("Our experts will visit your address soon.\n");

}

void main()

{

char name[40], custid[12]; //character arrays

int i,choice; 

puts("Hello, Welcome in the Electric Power Supply Office\n");

puts("May I know your 12 digit customer ID please:\n");

gets(custid); //function to receive customer ID

puts("May I know your name please:\n");

gets(name); //String function to receive name

printf("%s tell me what is your problem?\n", name);

choice=menu();

switch(choice)

{

    case 1:supplyoff();break; //calling the functions from main

    case 2:regcomp();break; //according to the switch value

    case 3:newconn();break;

    case 4:voltf();break;

    case 5:etheft();break;

    case 6:bookvisit();break;

    default:puts("Invalid input! Start again.");

}

}
