1. Define a flowchart. Write an algorithm and draw a corresponding
flowchart to create a simple multiple choice question (MCQ) examination of
25 questions for 50 marks along with evaluation process too.
Ans: Flowchart is a way to represent a programming process in graphical way. A
picture or diagram is an essential element to understand the complex problem. In
programming, such types of drawings are used for representing a program and
its process is known as Flowchart. “It is a pictorial representation of a
program”.

3. Discuss the significance of BITWISE operators in C programming
language. Also, write an interactive C program to illustrate them.
Bitwise operator
Operator
Description
&
Binary AND Operator copies a bit to the result if it exists in both operands.
|
Binary OR Operator copies a bit if it exists in either operand.
^
Binary XOR Operator copies the bit if it is set in one operand but not both.
~
Binary Ones Complement Operator is unary and has the effect of 'flipping' bits.
<<
Binary Left Shift Operator. The left operands value is moved left by the number of bits specified by
the right operand.
>>
Binary Right Shift Operator. The left operands value is moved right by the number of bits specified by
the right operand.
Example
Try the following example to understand all the bitwise operators available in C
programming language:
#include <stdio.h>
main()
{
unsignedint a = 50;
unsignedint b = 11;
int c = 0;
c = a & b;
printf("Value of c is %d\n", c );
c = a | b;
printf("Value of c is %d\n", c );
c = a ^ b;
printf(" Value of c is %d\n", c );
c = ~a;
printf("Value of c is %d\n", c );
c = a << 2;
printf("Value of c is %d\n", c );
c = a >> 2;
printf("Value of c is %d\n", c );

4. Define an array. Write an interactive C program to take two single
dimensional arrays of integers and merge them into a single dimensional
array, excluding the common elements of both the arrays.
Ans: In computer programming languages, an array is a group of objects with the
same attributes that can be addressed individually, using such techniques as
subscripting.
Memory representation of array- it allocates 10 bytes memory space for the 5integer value. It allocates contiguous memory location.
#include<stdio.h>
void sort(int a[])
{
inti,j,t;
for(i=0;i<=4;i++)
{
for(j=i;j<=4;j++)
{
if(a[i]>=a[j])
{
t=a[i];
a[i]=a[j];
a[j]=t;
}
}
}
}

{

6. Write an interactive C program to manage the assignments at study
centres for the first semester courses of MCA (MCS-011, 012, 13, 014, 015,
MCSL-016 and MCSL-017). Maximum marks for each assignment is 100
marks and weightage is 25%. Attending the viva-voce at the study centre for
each assignment iss percentage in each assignment is 40%.
