finding the length of the char array without '\0'

#include <stdio.h>
#include <string.h>
int main()
{
    char *s[]={"s","a","b"};
int a= sizeof(s) / sizeof(char *);  // 8(pointer char array) x 3(no.of char)=24 //24/8=3
printf("%d",a);

guessing a word with three times

guessing a word with three times in c using functions:-

#include <stdio.h>
#include <string.h>
void get_user_input(char *guess[10]);
int main(void)
{
const char secret[10] = "dinesh dk";
char guess[10];
int i;
for (i=0; i < 3; i++)
{
 get_user_input(guess);
 if (strcmp(secret, guess)==0)
 {
   printf("Your guess was correct");
   return 0;
 }
  else
 {
   printf("Your guess was incorrect. Please try again\n");
 }
 } 
return 0;
}
void get_user_input(char *guess[10])
{ 
 printf("Please guess the word: \n");
 scanf("%s", guess);
}

program for converting numbers to words

simple c program for converting numbers to words:-

#include<stdio.h>

int main()

{

int number,i=0,j,digit;

char * word[1000];

printf("Enter any integer: ");

scanf("%d",&number);

while(number)

{

digit = number %10;

number = number /10;

switch(digit)

{

case 0: word[i++] = "zero"; 

break;

case 1: word[i++] = "one"; 

break;

case 2: word[i++] = "two"; 

break;

case 3: word[i++] = "three"; 

break;

case 4: word[i++] = "four"; 

break;

case 5: word[i++] = "five"; 

break;

case 6: word[i++] = "six"; 

break;

case 7: word[i++] = "seven"; 

break;

case 8: word[i++] = "eight"; 

break;

case 9: word[i++] = "nine"; 

break;

}

}

for(j=i-1;j>=0;j--)

{

printf("%s ",word[j]);

}

return 0;
