/*there are some errors in program */
int main(); // there should not be semicolon after main()
{
int a,*b,**c,***d,****e;
a=10;
b=&a;
c=&b;
d=&c;
e=&d; // there should not be space between print and f
print f(“a=%d b=%u c=%u d=%u e=%u e=%u\n”, a,b,c,d,e); //an extra e=%u
print f(“ %d %d %d \n”,a,a+*b,**c+***d+,****e); //3 %d and 4 values to print, + is an unary operator so its format is like a+b.
return 0;
}
after correcting the errors the code becomes
int main()
{
int a,*b,**c,***d,****e;
a=10;
b=&a;
c=&b;
d=&c;
e=&d;
printf("a=%d b=%u c=%u d=%u e=%u \n", a,b,c,d,e);
printf(" %d %d %d %d\n",a,a+*b,**c+***d,****e);
return 0;
}
this will print
a=10 b= 0xf...(address of a) c=0xf....(address of b) d=0xf....(address of c) e=0xf....(address of d)
10 20 20 10
