C program to print how many times a character occurs in an array

Below is a C program which allows a user to enter a maximum of 10 characters. The program prints the count of how many times a given character occurs in the array.

/*Program to print how many times a given character occurs in an array*/
#include<stdio.h>
#include<conio.h>
void main()
{
    char arr[10],ch,i,num,flag=0,count=0;
    printf("How many characters you want to enter:");
    scanf("%d",&num);
    if(num>10)
    {
        printf("Size cannot be greater than 10.Try again...!");
    }
    else
    {
        /*Reading the array elements*/
        printf("Enter the array elements:\n");
        for(i=0;i<num;i++)
        {
            fflush(stdin);
            scanf("%c",&arr[i]);
        }
        /*Reading the character to search in the array*/
        printf("Enter the character you want to search:");
        fflush(stdin);
        scanf("%c",&ch);
        /*Code to check if the character is available in the array or not*/
        for(i=0;i<num;i++)
        {
            if(arr[i]==ch)
            {
                flag = 1;
                count++;
            }
        }
        if(flag==0)
        printf("Given character is not available in the array.");
        else
        printf("Given character '%c' occurs %d times in the array",ch,count);
    }
    getch();
}


Sample input and output:

How many characters you want to enter:6
Enter the array elements:
a
b
c
a
d
a
Enter the character you want to search:a
Given character 'a' occurs 3 times in the array
