#define swap1(a,b) a=a+b;b=a-b;a=a-b;

int swap2(int a,int b)

}
what are the outputs?
which of the following statements is incorrect
a.typedef struct new{
int n1;
char n2;
} DATA;
b.typedef struct {
int n3;
char *n4;
}ICE;
c.typedef union {
int n5;
float n6;
} UDT;
d.#typedef union {
int n7;
float n8;
} TUDAT;
consider the following C code
main()
{
int i=3,x;
while(i>0)
{
x=func(i);
i--;
}
int func(int n)
{
static sum=0;
sum=sum+n;
return(sum);
}
the final value of x is
consider the following program sigment
int n,sum=1;
switch(n) {
case 2:sum=sum+2;
case 3:sum*=2;
break;
default:sum=0;}
if n=2, what is the value of sum
a.0
b.6
c.3
d.none
The purpose of this exercise is to benchmark file writing
and reading speed. This exercise is divided into two parts.
a). Write a file character by character such that the total
file size becomes approximately >10K. After writing close
the file handler, open a new stream and read the file
character by character. Record both times. Execute this
exercise at least 4 times
b). Create a buffer capable of storing 100 characters. Now
after generating the characters, first store them in the
buffer. Once the buffer is filled up, store all the
elements in the file. Repeat the process until the total
file size becomes approximately >10K.While reading read a
while line, store it in buffer and once buffer gets filled
up, display the whole buffer. Repeat the exercise at least
4 times with different size of buffer (50, 100, 150 …).
Records the times.
c). Do an analysis of the differences in times and submit
it in class.
