In this tutorial, we will learn about how to create a program in C that will ask from user to enter any number to convert that number in words (characters). Let's first create a program that will print any given one-digit number (by user at run-time) in words. For example, if user enters 7, then the program prints Seven as output. Later on, you will get the code about printing number (contains more than 1 digit) in words.
// Print 1 digit Number in Word // ----codescracker.com---- #include<stdio.h> #include<conio.h> int main() { int num; printf("Enter the number (less than 10): "); scanf("%d", &num); printf("\n"); if(num<10 && num>0) { if(num==1) printf("1=>One"); else if(num==2) printf("2=>Two"); else if(num==3) printf("3=>Three"); else if(num==4) printf("4=>Four"); else if(num==5) printf("5=>Five"); else if(num==6) printf("6=>Six"); else if(num==7) printf("7=>Seven"); else if(num==8) printf("8=>Eight"); else if(num==9) printf("9=>Nine"); } else printf("Number must be in between 0 and 10"); getch(); return 0; }
As the program was written under Code::Blocks IDE, therefore here is the sample run after successful build and run:
Let's supply any number under 10 say 8 and press ENTER
key to see the output:
Let's create another program that prints any number (more than one-digit) by its digit-by-digit name (series of words). For example, if user enteres 8127, then program prints its output as Eight One Two Seven.
// Print Multiple digit Number in Words // ----codescracker.com---- #include<stdio.h> #include<conio.h> int main() { long int num, rev=0; int digit, rem; printf("Enter the number: "); scanf("%ld", &num); while(num>0) { rem = num%10; rev = rev*10 + rem; num = num/10; } while(rev>0) { digit = rev%10; switch(digit) { 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; case 0: printf("Zero "); break; default: printf("Something went wrong!!"); break; } rev = rev/10; } getch(); return 0; }
Here is the sample run after successful build and run:
Now supply any number say 8127 as input and press ENTER key. Here is the output you will see:
