1. What will be the output of the following C program segment? [GATE – 2012]
char inchar = 'A';switch (inchar){case 'A' : printf ("choice A n") ;case 'B' : printf ("choice B ") ; case 'C' :case 'D' :case 'E' :default: printf ("No Choice") ;} |
a. No choice
b. Choice A
c. Choice A
Choice B No choice
d. Program gives no output as it is erroneous
Answer : c)
2. Consider the following C code segment.
int a, b, c=0;
void prtFun (void);
main ()
{
static int a=1;
prtFun (); /* line*/
a+ =1;
prtFun ();
printf(“\n %d %d”,a,b);
}
void prtFun (void)
{
static int a=2;
int b=1; /* line*/
a+ = ++b;
printf (“\n %d %d”,a,b);
}
