C Pattern Programs: Square Number and Alphabet Patterns Explained

🔷 Square Star Pattern 📋 Copy Code #include <stdio.h> int main() { int num; printf("Enter the number:\n"); scanf("%d", &num); for(int i = 1; i <= num; i++) { for(int j = 1; j <= num; j++) { printf("* ");//keep"* " } printf("\n"); } return 0; } 🔷 Reverse Square Alphabet Pattern (Column-wise) 📋 Copy Code #include <stdio.h> int main() { int num; printf("Enter the number:\n"); scanf("%d", &num); for(int i = num; i >= 1; i--) { for(int j = num; j >= 1; j--) { printf("%c ", j + 64);//%c for Character and 64 will be ASIIC VALUE } printf("\n"); } return 0; } 🔷 Reverse Square Alphabet Pattern (Row-wise) 📋 Copy Code #include <stdio.h> int main() { int num; ...

A supermarket maintains a pricing format for all its products. A value N is printed on each product. When the scanner reads the value N on the item, the product of all the digits in the value N is the price of the item.

The task here is to design the software such that given the code of any item N the product (multiplication) of all the digits of value should be computed (price).

Example 1:

Input :

5244 -> Value of N

Output :
160 -> Price

Explanation:

From the input above

Product of the digits 5, 2, 4, 4

5 * 2 * 4 * 4 = 160

Hence, output is 160.


#include <stdio.h>

int subtractProductAndSum(int n)
{
    int product = 1;
    int sum = 0;

    while (n > 0)
    {
        int digit = n % 10;
        product *= digit;
        sum += digit;
        n /= 10;
    }

    return product - sum;
}

int main()
{
    int n;
    printf("Enter the value of N: ");
    scanf("%d", &n);

    int result = subtractProductAndSum(n);

    printf("Result (Product - Sum of digits): %d\n", result);

    return 0;
}
