#include<stdio.h>
#include<conio.h>


Togglebit(int k,int bit)
{
printf("after %d bit is toggled = %d",bit,(k^(1<<(bit-
1))));
return 1;

}
int main()
{
int i;
int bitno;
printf("enter the number \n");
scanf("%d",&i);
printf("enter the bit number to toggle \n");
scanf("%d",&bitno);
Togglebit(i,bitno);
getch();


return 1;
}

Result of the following program is main() { int i=0; for(i=0;i<20;i++) { switch(i) case 0:i+=5; case 1:i+=2; case 5:i+=5; default i+=4; break;} printf("%d,",i); } } a)0,5,9,13,17 b)5,9,13,17 c)12,17,22 d)16,21 e)syntax error
