Program 1: Word Pattern - Write a program or script in the programming language

Question

Program 1: Word Pattern - Write a program or script in the programming language of your choice to

Part 1: Word to Pattern

a. for any given string of characters, return the pattern.
For example, the word "apple" may be represented as the patterns abbcd or 01123 or 12234

b. The program should be able to take a string from console (typed word) or read words from a file

Part 2: Pattern to Word

a. for a given string of characters representing a word pattern, return possible candidate words (take advantage of words_aplha.txt and you may want to create a new file)
For example, the pattern "abbcd" will return a list of candidates as:

    apple
    essay
    reefs
    hooky
    leets
    wooly
:

Likewise if a word is entered "apple" then the candidate list is also returned

b. The program should be able to take a string from console (typed word) or read words from a file.

Explanation / Answer

#include<stdio.h>
#include<conio.h>  

void printDigit(int digit);
int main() {
int reverse = 0, digit, num, mod;
printf("Enter a positive Integer ");
scanf("%d", &num);

/* reverse the input number */
while (num > 0) {
reverse = (reverse * 10) + num % 10;
num /= 10;
}
num = reverse;

while (num > 0) {
digit = num % 10;
printDigit(digit);
num = num / 10;
}

getch();
return 0;
}

void printDigit(int digit){
switch (digit) {
case 0:
printf("Zero ");
break;
case 1:
printf("One ");
break;
case 2:
printf("Two ");
break;
case 3:
printf("Three ");
break;
case 4:
printf("Four ");
break;
case 5:
printf("Five ");
break;
case 6:
printf("Six ");
break;
case 7:
printf("Seven ");
break;
case 8:
printf("Eight ");
break;
case 9:
printf("Nine ");
break;
}
}
