The answer is 1 because where i%2 it gives 1 then if condition is true and it returns 0 to the main, again we call the function then if condition fails and then else part execute so answer is 1.

Ans :: C Because :: func(3) >>> return(1) >> i=1; func(1) >>> return(0) (because i is int type) >> i = 0 will be printed.
Read the folllowing code# define MAX 100# define MIN 100........if(x>MAX)x=1;else if(x<MIN)x=-1;x=50;if the initial value of x=200,what is the vlaue after executing this code?a.200b.1c.-1d.50

Ans :: 50Because at the end the value of x changes to 50 so 50 will be the result.

The ans is 50 irrespective of the initial value of x bcos at the end of the code we are overwriting the variable x with 50.
If we declare a pointer like char *p;how much memory is allocated for pointer variable 'p'.
