Question

Hi I have to write this in C and wasn't sure how! These are two separate codes to be done separately.

Write a program that accepts data from the user in the form mm/dd/yyyy and then displays it in the form of yyyymmdd (see below).

Enter a date (mm/dd/yyyy): 2/17/2011

You entered the data 20110217

Write a program that prompts the user to enter a telephone number in the form (xxx) xxx-xxxx and then displays the number in the format xxx.xxx.xxxx (see below).

Enter a phone number [(xxx) xxx-xxxx]: (404) 817-6200

You entered the data 404.817.6200

printf("Enter the date(mm/dd/yyyy): ");
scanf("%d/%d/%d",&mm,&dd,&yyyy);
printf("You entered the date %s %d,%d ",mon[mm-1],dd,yyyy);

return 0;
}

b)

#include<stdio.h>

int main()

{

char num[14];

char phone[12];

int i,j;

printf("\n Enter the phone no.[(xxx)xxx-xxxx] :");

scanf("%s",num);

printf("\n%s",num);

i=1;

j=0;

while(num[i]!='\0')

{

if(num[i]==')'||num[i]=='-')

phone[j]='.';

else phone[j]=num[i];

i++;j++;

}phone[j]='\0';

printf("\n%s",phone);

}
