Thread: Count the number of vowels, consonants, digits etc.

Hi! All
Here I am trying to write a programme, which will accept a line of text and count the vowels, consonants, digits, whitespaces & others like (.,;,).
The code i am using is :

Code:

#include<stdio.h>
#include<conio.h>
#include<ctype.h>
void scan_line(char *line, int *pv, int *pc, int *pd, int *pw, int *po);
void main()
{
  char *line;
  int vowels=0;
  int consonants=0;
  int digits=0;
  int whitespace=0;
  int others=0;
  clrscr();
  printf("Enter a line of text below : \n");
  scanf("%s",line);
  printf("%s",line);
  scan_line(line,&vowels,&consonants,&digits,&whitespace,&others);
  printf("\n No. of vowels: %d",vowels);
  printf("\n No. of consonants: %d",consonants);
  printf("\n No. of digits: %d",digits);
  printf("\n No. of whitespace: %d",whitespace);
  printf("\n No. of other characters: %d",others);
getch();
}


void scan_line(char *line, int *pv, int *pc, int *pd, int *pw, int *po)
{
  char c;
  int count=0;
  while((c=toupper(line[count]))!='\n')
  {
    if(c=='A'||c=='E'||c=='I'||c=='O'||c=='U')
       ++*pv;
     else if(c>='A'&& c<='Z')
	++*pc;
     else if(c>='0'&& c<='9')
	++*pd;
     else if(c==' '|| c=='\t')
	++*pw;
     else
	++*po;

   ++count;
   }
   return ;
}

But it is not returning the desired result. 
Please help Anil.
