            printf("enter no: ");
            scanf("%d", &num);

            result = num;
            
            printf("Reverse no is %d", result); 
          
            return 0; 
        } 

     
3. Write a program in c to make a table of a given number.

        #include <stdio.h>
        int main()
        {
            int num, result;

            printf("enter no: ");
            scanf("%d", &num);

            for(int i = 1; i <= 10; i++){
                result = num * i;
                printf("%d * %d = %d \n",num, i, result);
            }

            return 0;
        }
 
     
4. Write a program in c to find the factorial of given number.

    #include <stdio.h>
 
    int main() {
    int n, fact = 1;
    printf("Enter an integer: ");
    scanf("%d", &n);

    if (n < 0) {
        printf("negative number doesn't exist.");
     } else {
        for (int i = 1; i <= n; ++i) {
            fact *= i;
        }
        printf("factorial of %d is = %d", n, fact);
    }

    return 0;
    }

    
5. Write a program in c to sum of digits of a given number.

    #include <stdio.h>

        int main()
        {
            int num, sum=0;
        
            printf("enter number: ");
            scanf("%d", &num);
        
            while(num!=0)
            {
                sum += num % 10;
                num = num / 10;
            }
        
            printf("sum of digits = %d", sum);
        
            return 0;
        }

     
9. Write a program in c to print all alphabet from a to z.

        #include <stdio.h>

        int main()
        {
            char ch;
        
            printf("prints alphabets: \n");
            for(ch='a'; ch<='z'; ch++)
            {
                printf("%c\n", ch);
            }
