We can even write the program like this: #include Дecimal Equivalent of 10011 is 19 Number SystemsДЎ. Printf('Decimal Equivalent of %ld is ', num) Source Code: C Program To Convert Binary Number To Decimal Number, using While Loop #include And then add this value to previous value of variable dec.

i.e., if fetched digit is from position 3, then we use pow(2, 3) to calculate its decimal equivalent value i.e., 2 x 2 x 2 = 8. If the fetched value is 1, then we check the place value and use pow() method to place it properly in the Binary number system. Using while loop we fetch digits of that user entered number one by one. In this C program we ask the user to enter / input a binary number.

Else the number has at least one factor and not a prime.YouTube Link: Logic To Convert Binary Number To Decimal Number, using While Loop.

Outside the loop check if ctr is zero, hence the number has no factors and is a prime number, then print it.

If i/j is equal to zero hence j is factor i, then set ctr=1 and break the loop.

Start a for loop from j=2 to j=i to check for factors.

Initialize a variable ctr=0 to count the number of factors.

Start a for loop from i=2 to i=100, which will set each number.

To prove this letвЂ™s presume a factor of i as j such that j>i then there must be another factor i/j which will be smaller than i since both the factors canвЂ™t be greater than i, therefore, if there are no factors of i less than i then the number doesnвЂ™t have any other factor. Note: The loop will run till i and not till i because if a number has no factors till i then it wonвЂ™t have any factor. Inside it, we will use another for loop from 2 to i to check for factors. We will use a for loop from 2 to 100 to set the number to be checked. To print all the prime numbers between 1 and 100 we would have to start from 2 (since 1 is neither prime nor composite) and then check for each numberвЂ™s factors.

One is considered neither prime nor composite. Rest of the numbers are called composite numbers. In the given question, we have to find and print all prime numbers between 1 and 100.ДЄny number is called a prime number if it has no factors other than one and the number itself.
