Answer :

Explanation
The three usages of name errors can be distinguishable
by the compiler at any instance, so valid (they are in
different namespaces).
Typedef struct error{int warning, error, exception;}error;
This error can be used only by preceding the error by struct
kayword as in:
struct error someError;
typedef struct error{int warning, error, exception;}error;
This can be used only after . (dot) or -> (arrow) operator
preceded by the variable name as in :
g1.error =1;
printf("%d",g1.error);
typedef struct error{int warning, error, exception;}error;
This can be used to define variables without using the
preceding struct keyword as in:
error g1;
Since the compiler can perfectly distinguish between these
three usages, it is perfectly legal and valid.
Note
This code is given here to just explain the concept
behind. In real programming don’t use such overloading of
names. It reduces the readability of the code. Possible
doesn’t mean that we should use it!

Which version do you prefer of the following two, 1) printf(“%s”,str); // or the more curt one 2) printf(str);
main() { int i; float *pf; pf = (float *)&i; *pf = 100.00; printf("\n %d", i); } a. Runtime error. b. 100 c. Some Integer not 100 d. None of the above
void main() { static int i=5; if(--i){ main(); printf("%d ",i); } }
main() { int c = 5; printf("%d", main||c); } a. 1 b. 5 c. 0 d. none of the above

create a C-code that will display the total fare of a passenger of a taxi if the driver press enter,the timer will stop. Every 10 counts is 2 pesos. Initial value is 25.00
main( ) { static int a[ ] = {0,1,2,3,4}; int *p[ ] = {a,a+1,a+2,a+3,a+4}; int **ptr = p; ptr++; printf(“\n %d %d %d”, ptr-p, *ptr-a, **ptr); *ptr++; printf(“\n %d %d %d”, ptr-p, *ptr-a, **ptr); *++ptr; printf(“\n %d %d %d”, ptr-p, *ptr-a, **ptr); ++*ptr; printf(“\n %d %d %d”, ptr-p, *ptr-a, **ptr); }
what will be the output of this program? void main() { int a[]={5,10,15}; int i=0,num; num=a[++i] + ++i +(++i); printf("%d",num); }

There is a lucky draw held every day. if there is a winning number eg 1876,then all possible numbers like 1867,1687,1768 etc are the numbers that match irrespective of the position of the digit. Thus all these numbers qualify fr the lucky draw prize Assume there is no zero digit in any numbers. write a program to show all the possible winning numbers if a "winning number"is passed as an arguments to the function.
main() { int *j; { int i=10; j=&i; } printf("%d",*j); }
