Write as a shell script

Write as a shell script # include <stdio.h> int main (void) {int area_code, prefix, number; printf("Enter phone number [(999) 999-9999]:"); scanf("(%d)%d-%d", &area_code, & prefix, & number); printf("You entered %d-%d-%d \n", area_code, prefix, number); return 0;}

Answer 1

Shell Script:

#!/bin/bash

#Bash Script that reads one number in one format and changes into another format

#Reading phone number
echo "Enter Phone number [(999) 999-9999]: ";
read phoneNo;

#Removing '('
temp="${phoneNo//(}"
phoneNo=$temp

#Removing ')'
temp="${phoneNo//)}"
phoneNo=$temp

#Removing '-'
temp="${phoneNo//-}"
phoneNo=$temp

#Forming new phone number
newPhoneNo=$(echo "${phoneNo:0:3}- ${phoneNo:4:3}- ${phoneNo:7:4}")

#Printing new phone number
echo "You entered: "$newPhoneNo
