Is the following statement a declaration/definition. Find what does it mean? int (*x)[10];
Declare an array of N pointers to functions returning pointers to functions returning pointers to characters?
find A^B using Recursive function
main(){ unsigned int i; for(i=1;i>-2;i--) printf("c aptitude"); }
What are the files which are automatically opened when a C file is executed?
What is the hidden bug with the following statement? assert(val++ != 0);
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() { char *a = "Hello "; char *b = "World"; clrscr(); printf("%s", strcpy(a,b)); } a. “Hello” b. “Hello World” c. “HelloWorld” d. None of the above

main(){ char a[100]; a[0]='a';a[1]]='b';a[2]='c';a[4]='d'; abc(a); } abc(char a[]){ a++; printf("%c",*a); a++; printf("%c",*a); }
Print an integer using only putchar. Try doing it without using extra storage.
