C Programming

What will be the output of the following C program segment?

char inChar = 'A' ;
switch ( inChar ) {
case 'A' : printf ("Choice A\n") ;
case 'B' :
case 'C' : printf ("Choice B") ;
case 'D' :
case 'E' :
default  : printf ( " No Choice" ) ; }

Common data for Q.48 and Q.49: Consider the following C code segment.

int a, b, c = 0;
void prtFun(void);
main( )
{   static int a = 1;              /*  Line 1 */
    prtFun( );
    a += 1;
    prtFun( );
    printf(" \n %d  %d ", a, b);
}

void prtFun(void)
{   static int a = 2;              /*  Line 2 */
    int b = 1;
    a += ++b;
    printf(" \n %d  %d ", a, b);
}

What output will be generated by the given code segment?
