Write a C program to perform the arithmetic operation. Here, the preprocessor replaces "printf" in place of "out" and "scant" in place of "in" before compilation of program. Therefore, the word can be defined as macro. Note** #define out printf** #define in scanf.

Input:

6.5

3.3

Output:

9.8

A college has to generate the roll number of the students for the internal examination. The college admin authority has to generate the roll numbers from the registration number of the students. Every student has a registration number. The registration number is a numeric number. The authority has devised a method for generating the roll numbers from the registration number. To generate the roll number, the pairs of adjacent digits are formed from the start of the roll number. From each pair the lexicograpically smallest digit will be removed. If a digit will be left unpaired then that digit will be taken as it is in the roll number.

Write an algorithm for implementing the devised method for the college system to find the roll number from the registration number.

Write a c++ program for the World Bowling Competition. An input file, score.txt, contains the name of each player, the name of the player's team and each player's individual score. There will only be two teams(Blue and White). Read the data from the input file into three parallel arrays.The program must accumulate the total score for each team and then output the name of the winning team and the player's names and score of the winning team. Assume there is no chance of a tie. Use functions to:

1) Read the data from the input file into parallel arrays,

2) Determine the winning team,

3) Display the winning team's player names and scores
