problem 1) prepare a program to convert a octal number to binary number.

problem 2) prepare a program to convert a hexadecimal number to the binary number.

problem 3) prepare a program to generate all combinations of 1, 2 and 3.

problem 4) prepare a program to find out the LCM and GCD of two given numbers.

problem 5) prepare a program to find out the least common divisor of two integers

problem 6) prepare a program to check whether square root of a number is prime or not.

problem 7) Input two numbers from the keyboard. prepare a program to find the value of one number raised to the power of another.

problem 8) prepare a program to print all the ASCII values and their equivalent characters. The ASCII values vary from 0 to 255.

problem 9) prepare a program to check that given number is Armstrong number or not. ( if the sum of the cubes of each digits of the number is equal to the number itself, then the number is called the Armstrong number. For ex, 153 = (1*1*1) + (5*5*5) + (3*3*3).

problem 10) 145 is a special number, since it satisfies the following relation:

145 = 1! + 4! + 5! = 1+24+120 =145

WAP to print all the numbers of this kind between 1 – 1000000.

problem 11) prepare a program to find out the sum of geometric series.

problem 12) prepare a program to print out all Armstrong numbers between 1 and 500.

problem 13) Square of 12 is 144. 21, which is a reverse of 12 has a square 441, which is same as 144 reversed. There are few numbers which have this property. prepare a program to find out whether any more such numbers exist in the range of 10 to 100.

problem 14) prepare a program to find out the difference between two dates in terms of numbers of days.

problem 15) prepare a program to input n numbers and find out the sum, average, maximum and minimum of the given numbers. (use only one variable to input the number and also find the second largest).
