Answer:
Following are the program, which can be below:
#include <stdio.h> //defining header file
#include <string.h>//defining header file
int main() //defining main method
{
int x=0,y=0,l=0; //defining integer variable
char phone_number[32] = {'\0'}; //defining char array
printf("Enter a date(xxx-xxx-xxxx): \n "); //print message
printf("Example: 000-000-0000 \n :"); //print message
scanf("%s",phone_number); // taking input from user
printf("%s\n",phone_number); //print number
for(x=0; phone_number[x]; x++) // check character by character
{
if(x==0) // put ( on first character
{
l = strlen(phone_number); //calculate length
phone_number[l] = '\0'; //check number
for(y=l; y>=1; y--) //loop to calculate a value
{
phone_number[y] = phone_number[y-1]; //holding value in array
}
phone_number[y] = '('; //assigning bracket
}
if(phone_number[x] == '-') // put ) at first -
{
phone_number[x] = ')'; //assigning bracket
break;
}
}
printf("You entered %s\n",phone_number); //print all value with brackets
}
Output:
Enter a date(xxx-xxx-xxxx):
Example: 000-000-0000
:011-123-4567
011-123-4567
You entered (011)123-4567
Explanation:
The description of the above program can be defined as follows:
- In the above program three integer variable "x, y, and l" and a character array "phone_number" is declared.
- In the char, variable user input the value and print its value by using the print function.
- In the next line, a for loop is declare, that checks user input value character by character and counts its length by using the strlen() method, inside the loop a conditional statement is used.
- In the condition statement check, the values are not equal to null and provide brackets in the inserted value.
