How many 4 digit numbers are there that do not contain 3 or 6?

How many four-digit numbers that do not contain the digits 3 or 6 are there? Actual solution states that the first digit has 7 possibilities which excludes 0,3,& 6. And the other 3 digits have 8 possibilities. So the total possibilities are 7 * 8 * 8 * 8==3584.

How to display the sum of two integer numbers in C?

In the first program, the user is asked to enter two integer numbers and then program displays the sum of these numbers. In the second C program we are doing the same thing using user defined function. To read the input numbers we are using scanf () function and then we are using printf () function to display the sum of these numbers.

How to add or remove one digit at a time?

To add digits of a number we have to remove one digit at a time we can use ‘/’ division and ‘\%’ modulus operator. Number\%10 will give the least significant digit of the number, we will use it to get one digit of number at a time. To remove last least significant digit from number we will divide number by 10.
