20) What is the output of following C code? Justify.

 

1) int main ( )

 {

static char name [] = “programming”;

char *s ;

 s = & name [6] - 4;

 while (*s)

printf (“%c”, * s ++);

}

2)

What is the output of following C code? Justify.

 # define Test (x) (x * x)

 int main ( )

 {

int a, b = 3;

a = Test (b + 3);

printf (“% d - % d”, a, b);

 }

4) #include<stdio.h>

int main()

{

int a =5, b=10, c=7;

predict (a,&b,c);

printf("%d - %d - %d",a,b,c);

}

void predict(int p,int *q,int r)

{

p = 50;

*q =*q * 10;

r = 77;

}

5)

# include<stdio.h>

 int main ()

 {

 char str[100];

char *ptr;

 strcpy(str, “India is GREAT”);

 ptr = str + strlen (str);

 printf (“The string is:”);

 while (*ptr ! = str)

printf (“%c”, *ptr --);

return 0;

}
