C Programming

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?

What output will be generated by the given code segment if: Line 1 is replaced by auto int a = 1; Line 2 is replaced by register int a = 2;

Common Data for Questions 48 and 49: Consider the following recursive C function that takes two arguments.

unsigned int foo(unsigned int n, unsigned int r) {
    if (n>0) return ((n%r) + foo(n/r, r));
    else return 0;
}

What is the return value of the function foo when it is called as foo(345, 10)?
