customer service system. Your system is archaic, so you can only read in the inputs 1

through 4, `y’ `n’ and `q’ from your user (the current customer).

When your program begins, display the following menu to the user:

[prompt]$./customer_experience

WelcometoCableCom!Pleasemakeachoicefromthefollowingoptions:

1)Changeyourpassword

2)Cancelyourservice

3)Scheduleaservicecall

4)Payyourbill

Your system then asks a series of questions. After picking an option, ask the user if

they would like to upgrade their service. A service upgrade message looks like this:

Youareeligibleforalimitedtimeoffer.Youcanget%dmegabits

persecondforthelowpromotionalrateof$%damonth.Actnowwhile

supplieslast.

Here, the two %dvariables depend on the options and the user’s actions (specified

below). They may either input `y’ for yes, `n’ for no, or `q’ for quit. If at any point in

time the user enters `y’, they have decided to upgrade their service! Congratulate them

by printing:

Greatchoice.Goodbye.

And exit the program. Your service upgrade messages and behavior on `q’ is as

follows, depending on the option chosen above:

Option 1

Begin your service upgrade at 10 megabits per second for $50 dollars a

month. Every time the customer enters `n’ or `q’, increase both the

megabits per second and dollars a month by 1.

After any prompt, exit if `q’ has been pressed twice (not necessarily in a

row).

That is the program I'm supposed to construct and I have the following codes so far:

#include

int main() {

int entry;

printf("Welcome to CableCom! Please make a choice from the following options: 1) Change your password 2) Cancel your service 3) Schedule a service call 4) Pay your bill");

scanf("%d", &entry);

while (entry < 1 || entry > 4)

printf("Please enter a number between 1 and 4.")

(entry => 1 && entry =<4)

I do not know how to proceed from here and would really appreciate help completing this. I'm using C programming language.

#include<stdio.h>

void main()
{

int mbpersec;
int fee;

int choice1;
char choice2;
int qcounter=0;
int flag=1;
mbpersec=10;
fee=50;

while(flag)
{
printf(" WelcometoCableCom!Pleasemakeachoicefromthefollowingoptions: ");

printf("1.Changeyourpassword ");
printf("2.Cancelyourservice ");
printf("3.Scheduleaservicecall ");
printf("4.Payyourbill ");

scanf(" %d",&choice1);
printf("service %d selected by customer. Displaying current offer below ",choice1);
fflush(stdin);

if(choice1 >=1 && choice1 <= 4){
printf(" Youcanget%dmegabitspersecondforthelowpromotionalrateof$%damonth.Actnowwhilesupplieslast. ",mbpersec,fee);
printf(" Enter y/n/q : ");
scanf(" %c", &choice2 );
fflush(stdin);
switch(choice2){

case 'y':
printf("Greatchoice.Goodbye. ");
printf("4 ");
flag=0;
break;

case 'n':
mbpersec=mbpersec+1;
fee=fee+1;
break;

case 'q':
mbpersec=mbpersec+1;
fee=fee+1;
qcounter=qcounter+1;
if(qcounter==2){flag=0;}
break;
}


}else{
printf("Please enter your choice between 1 to 4 only ");
continue;
}

}

}
