(i) If int i = 7, float f = 5.5, char c='a', What will be the output of (a)'i+c' and (b) 'i+f?

(ii) If int result, i=7, f=8.5, What will be the output of 'result=(i+f)%4'

(iii) If float num = 10.5, What will be the output of 'num%2' and '((int)num)%2'

What will be the simplified form of the following

(i) !(a<b)

List the syntax error (if any) of each line of the following code (copy the code on you script, mark the error by placing an underline and then explain that error, if you indicate anything as syntax error but really that is not a syntax error, then equivalent negative mark will be given)?

#include <stdio>

main()

{

Int x,y

scanf("%dd",&x,&y);

switch (x)

{ case(x<0): printf("x is negative"); break;

case (x>0); printf("x is negative");}

x=fl (y);

printf("Final value of = %d\n", x); }

void fl (int y)

{

y=y*y;

return y;

}

Define escape sequence. List any 5(five) escape sequences used in C programming.

Distinguish between unary and binary operator with example.

Find the output of the following code.

void main() {

int a=, b=15, r, s;

float a, b, c;

a=i/j;

}

How do do-while and while statement differ? When is a for, do-while, or while control statement preferable to use?

What is the purpose of break statement? Suppose you are given an integer (positive and negative) type array containing n elements. Write a C code to find the position of first occurrence of negative number in an array. It is required to stop the searching when the first negative integer is found.

Write a statement to create an infinite loop using while loop .

What is dynamic memory allocation?

Write C program for the following problem, it does not need to think about run-time optimization. (Objective of the question: To check the standard analytical capacity of a student of 1 year as well as to check his/her problem understanding capacity)

The chairman of the dept. of CSE of Barishal University is popular for arranging regular innovative events for his students. One day, he planned to arrange a game for the students of 1st year in their electronics lab, and he declared that the winner would be awarded a special prize. As a result, all of the N number of students participated in that game. The chairman brought a basket that contained many balls; having three different colors: red (R), green (G) and blue (B). The numbers of balls of each color were equal and total number of the balls in the basket was 3N; however, the weights of the balls were different and were indicated by an integer number printed on respective ball. The chairman told the students to come up to him one by one and take exactly one red, one green and one blue ball within a second; the point earned by that student would be the product of the value of weights of the respective balls picked up by that student. Therefore, each student tried to pick the balls with the largest weights printed on them.

Input:

The input will have four lines; first line will contain an integer N, the number of students and the next three lines will contain the weights of the different red, green and blue colored balls respectively. For example:

4

5 6 11 3

9 8 2 7

6 2 4 8

What are different types of user defined functions used in C? Explain.

Write C program for the following problem, it does not need to think about run-time optimization. (Objective of the question: To check the problem understanding capacity)

One day, one of the students of CSE dept. named Sumon is having a party, and he has invited his friends, p of them have arrived already, but some other are running late. To occupy his guests, Sumon tried playing some team games with them, but he found that it was impossible to divide the p guests into any number of equal-sized groups of more than one person. As a result, he had to wait until q guest(s) arrived, q may be single guest or group of guests arrived at the same time. Finally, summon could make teams of equal sized from the arrived (p+q) guests and started his games.

Input

The input will consist of 5 test cases. Each test case will be given as a non-negative integer (p+q) and (p+q) <100;

Output

For each test case, output will be an integer q that is closest to (p+q)
