C program to print given number in words

• Write a program to input a digit and print it in words
• C program to print number in words using switch cas.
• Now we will see how to convert number /digits in to words in C programming.
• Get the input from the user using Scanf() function.
• Using while loop and % operator and get the each number and use switch case to print corresponding word for the current number.

Program #1: write a program in c that reads the digits and then converts them into words

1. #include <stdio.h>
2. #include <stdlib.h>
3. int main(int argc, char *argv[])
4. {
5.  int number,i=0,j,digit;
6.     char * word[1000];
7.  
8.     printf("Enter any integer to print that in words: ");
9.     scanf("%d",&number);
10.  
11.     while(number){
12.  
13.     digit = number %10;
14.     number = number /10;
15.  
16.          switch(digit){
17.              case 0: word[i++] = "zero"; break;
18.              case 1: word[i++] = "one"; break;
19.              case 2: word[i++] = "two"; break;
20.              case 3: word[i++] = "three"; break;
21.              case 4: word[i++] = "four"; break;
22.              case 5: word[i++] = "five"; break;
23.              case 6: word[i++] = "six"; break;
24.              case 7: word[i++] = "seven"; break;
25.              case 8: word[i++] = "eight"; break;
26.              case 9: word[i++] = "nine"; break;
27.  
28.         }
29.     }
30.    
31.     for(j=i-1;j>=0;j--){
32.          printf("%s ",word[j]);
33.     }
34.  return 0;
35. }

  
Output:
