Practice Structures, Unions, Enums – If an integer occupies 4 bytes and a character occupies 1 byte of memory, each element of the following structure would occupy how many bytes?
struct name {
int age;
char name[20];
}
Practice Floating Point Issues – What would be the value of i and k in below C program?
void main() {
int i,j,k;
j = 5;
i = 2 *j/2;
k = 2 *(j/2);
}
Practice Declarations and Initializations – A declaration “short int” is used for variables
Practice Input / Output – if i,j,k are integers, the scanf function to enter i,j,k such that i is decimal,j is octal and k is hexadecimal would be
Practice Control Instructions – What is the output of the below fragment of C code, if i = 3?
if (i >1)c = 2;
else c = 3;
switch (c) {
case 2: printf("CAUTION");
break;
case 3: printf("GOOD BYE");
break;
default : printf("TERROR");
}
Practice Structures, Unions, Enums – Consider the following definitions
struct circle {
float radius;
struct point centre;
} circle cl;
struct point {
int x;
int y;
}
One can define a circle by the following assignment statement
Practice Bitwise Operators – If the following variables are set to the values as shown below, then what is the value of the expression following it?
answer= 2;
marks= 10;
!((answer < 5) || (markes > 2 ))
Practice Basic Concept – The following lines, if included in a program, will cause which of the following errors?
double c;
scanf(“%c”,c);
Practice Variable Number of Arguments – What is the output of the following program?
void main()
{
float balance, loan;
balance = 1000.0;
loan= balance/10;
if ((balance>500) || (loan < 500))
printf ("Good account/n ");
if (balance < 500) || (loan < 500)
printf("caution !/n");
}
Practice Declarations and Initializations – What will be output of the following “c” code?
#include
void main ( )
{
int i, m=2, n=3;
for( i=0;m+n=5; m++)
printf("%d %d", m,n);
}
Practice Control Instructions – What is the output of the following program?
void main()
{
int B, X, Y, Z;
X=1; Y=2; Z=3;
jf ((X > 1) || (Y > 1))
if (Z > 1)
printf ("O.K /n");
else break;
if((X > 1 && (Z > 3))
printf ("Bye /n");
printf ("Hello!");
}
Practice Basic Concept – The following program fragment will give a ?
void main()
{
int sum, index,
-index= 50;
while (index > = 0) {
sum = sum / index;
-index;
} }
Practice C Preprocessor – The output of the following program is
#define two (x) 2*x
#define ddouble (x) x + x
void main()
{
int num, sum, product;
num = 1;
sum = - two (num); sum = -(sum + 1);
product = - ddouble (num);
printf ("%d%d/n" ,sum,product);
}
Practice C Preprocessor – What is the value of variable POLYGON?
void main ()
{
int POLYGON, L, B;
L = B = 2;
POLYGON= (L = = B)? 1:0;
}
Practice Declarations and Initializations – What is the output of the following program?
void main()
{
int x,y, z;
x=2; y=1; z = 1;
if(x > y + z)
printf("Hello!
");
else if (x < y+ z)
printf ("Hi!
");
else
printf("Hey!
");
}
