Input two integer values from keyboard and swap their contents without using any other temporary variable. Read the price of an item (rupees) in float and display number of paise. Convert the Celsius temperature input from keyboard into its Fahrenheit equivalent using following formula: C = (F – 32) /1.8 Accept the value of money in rupees and convert it into dollars. Determine the sum of following series: 1 + 1/2 + 1/3 + …….. 1/n. take n as input Print the Fibonacci series on the screen by taking n as input from keyboard: 1 1 2 3 5 8 ……. n -1-

Find squares of all the numbers from 1 to n. Accept a number as input and find its sum of digits. Input a number and print it in reverse order. Input a long number from keyboard and count total number of even digits in it. Find the number of and sum of all the integers greater than 100 and less than 200 that are divisible by 7. Accept marks of 10 different students from keyboard and analyze it. That is, count total first, second and pass class students. Making the use of continue statement find whether the entered number is prime or not? Count how many perfect square numbers are also perfect cube numbers from 1 to 1000. Determine whether the entered number is palindrome or not? (A palindrome number is read same from both front and back sides such as 56365, 812218, 121 etc.) Print following output using for loops: * ** *** **** Count how many perfect square numbers are palindrome numbers from 1 to 10000. Input the clock time and find the angle made between the ticks of the analog clock. Accept a number from keyboard and find its roman and binary equivalent. Find all the natural Armstrong numbers For example: 153 is an Armstrong number satisfies this property: 153 = 13 + 53 + 33.
