Example for character functions:


/* Program to count the number of vowels */



# include < stdio.h >
main ( )
{
char word[30];
int j=0, a=0, e=0, o=0, u=0, i=0;
printf( " \n Enter any word " );
scanf( "%s",word );

while( word[j] != '\0' )
{
   switch ( word[j] )
  {
    case 'a' :
    case 'A' : a++; break;

    case 'e' :
    case 'E' : e++; break;

    case  'i' :
    case 'I' : i++; break;

    case 'o' :
    case 'O' : o++; break;

    case 'u' :
    case 'U' : u++; break;
}
j++;
}
printf( " \n a=%d \n e=%d \n i=%d \n o=%d \n u=%d ",a,e,i,o,u );
}
