Answer:

Output:

Alphabetic_letters = 3, Decimal_digits = 4

Explanation:

// C program to demonstrate working of isalpha() and  

// isdigit().  

#include<stdio.h>  

#include<stdlib.h>  

 

int main()  

{  

   char str[] = "12abc12";  

 

   int alphabet = 0, number = 0, i;  

   for (i=0; str[i]!= '\0'; i++)  

   {  

       // check for alphabets  

       if (isalpha(str[i]) != 0)  

           alphabet++;  

 

       // check for decimal digits  

       else if (isdigit(str[i]) != 0)  

           number++;  

   }  

 

   printf("Alphabetic_letters = %d, "

          "Decimal_digits = %d\n", alphabet, number);  

 

   return 0;
