Logic [ Algorithm ]: 

1. Accept the String from the user.
2. Also Accept the character to be searched
3. String is stored as array of character , then scan each array elementwith entered character.
4. If it matches then increment the Counter by 1 else go for another character.

int count=0,i;
clrscr();

printf("\nEnter a string : ");
scanf("%s",&str);

printf("\nEnter the character to be searched : ");
scanf("%c",&ch);

  for(i=0;str[i]!='';i++)
    {
    if(str[i]==ch)
         count++;
    }

 if(count==0)
     printf("\nCharacter '%c'is not present",ch);
 else
     printf("\nOccurence of character '%c' : %d",ch,count);

getch();
