Write a C program to print numbers in words using elseif statements
Problem
Without using a switch case, how can you print a given number in words using the C programming language?
Solution
In this program, we are checking three conditions to print a two-digit number in words −
if(no<0 || no>99)
entered number is not a two digit
else if(no==0)
print first number as zero
else if(no>=10 && no<=19)
Print single digit number in words
else if(no>=20 && no<=90)
if(no%10 == 0)
Print two-digit number in words
Program
#include<stdio.h>
#include<string.h>
int main(){
int no;
char *firstno[]={"zero","ten","eleven","twelve","thirteen", "fourteen","fifteen","sixteen","seventeen", "eighteen","nineteen"};
char *secondno[]={"twenty","thirty","forty","fifty","sixty", "seventy","eighty","ninty"};
char *thirdno[]={"one","two","three","four","five","six","seven","eight","nine"};
printf("enter a number:");
scanf("%d",&no);
if(no<0 || no>99)
printf("enter number is not a two digit number
");
else if(no==0)
printf("the enter no is:%s
",firstno[no]);
else if(no>=10 && no<=19)
printf("the enter no is:%s
",firstno[no-10+1]);
else if(no>=20 && no<=90)
if(no%10 == 0)
printf("the enter no is:%s
",secondno[no/10 - 2]);
else
printf("the enter no is:%s %s
",secondno[no/10-2],thirdno[no%10-1]);
return 0;
}Output
enter a number:79 the enter no is: seventy nine enter a number:234 enter number is not a two digit number
