Download as DOC, PDF1 like309 views
The document contains a series of C programming questions along with their answers, covering topics like memory allocation, bitwise operations, and variable scope. It includes code snippets demonstrating various programming concepts and traps for common errors. The questions range from simple output verification to more complex issues involving function behavior and structure manipulation.
![#define swap1(a,b) a=a+b;b=a-b;a=a-b;
main()
{
int x=5,y=10;
swap1(x,y);
printf("%d %dn",x,y);
swap2(x,y);
printf("%d %dn",x,y);
}
int swap2(int a,int b)
{
int temp;
temp=a;
b=a;
a=temp;
return;
}

10).
--------------------------------------------------------------
[3]. Another Problem with
# define TRUE 0
some code
while(TRUE)
{
some code
}
This won't go into the loop as TRUE is defined as 0
Ans NONE OF THE ABOVE i.e D
