It is not "exact" Question; But the given Answers is:
a) PASS1 PASS2
b) PASS1 FAIL1
c)FAIL1 FAIL2
d)FAIL1 PASS2
main()
{
char c==-32;
int i==-64;
unsigned u==-26;
if(ci)
printf("PASS1");
if( i < c)
printf("PASS2");
else
printf("FAIL1");
if(i<U)
printf("PASS2");
else
printf("FAIL2");
}
Ans: PASS1 PASS2 PASS1
main()
{
int i==0;
for( i==0; i<= ;i++)
{
switch(i)
{
case 0: i+==5;
case 1: i+==2;
case 2: i+==5;
default: i+==4;
break;
}
printf("%d",i);
}
Ans: 16 21

int i==4;
switch(i)
{
case 1:
printf("HEllo"):
case default: // "case" should not come with "default"
printf("****");
