main()
{
            int a;
            printf("Enter a three digit number\n");

            int p = a % 10;
            int y=  a / 10;
            int q = y % 10;
            int o = y / 10;
            int r = o % 10;
            int c =  p * 100 + q * 10 + r * 1;
            printf("%d",c);
}

Q. WAP to Find Sum of N Numbers ?

main()
{
    int N, sum = 0;

    scanf("%d", &N);
    sum = N * (N+1) / 2;
    printf("The sum of all numbers between 0 and %d is: %d", N, sum);
}

Q. WAP to Display the Table of any Number Entered by user ?

main()  
{

{
r=no%10;
no=no/10;
res=(res*10)+r;
}
printf("\nReverse is %d",res);
}
