          {
              int x=20,y=35;
              x=y++ + x++;
              y= ++y + ++x;
              printf("%d%d\n",x,y);
          }

Deteting Circular Linked List
Can you tell me how to check whether a linked list is circular? Create two pointers, and set both to the start of the list. Update each as follows: while (pointer1) { pointer1 = pointer1->next; pointer2 = pointer2->next; if (pointer2) pointer2=pointer2->next ;if (pointer1 == poi... 2007-02-26, 7320👍, 0💬

"union" Data Type
What's the output of the following program? And why? #include main() { typedef union { int a; char b[10]; float c; } Union; Union x,y = {100}; x.a = 50; strcpy(x.b,"hello"); x.c = 21.50; printf("Union x : %d %s %f n",x.a,x.b,x.c); printf("Union y : %d %s %f n",y.a,y.b,y.c); } 2007-02-26, 7263👍, 0💬

Printing Permutaions of a String
Write out a function that prints out all the permutations of a string. For example, abc would give you abc, acb, bac, bca, cab, cba. void PrintPermu (char *sBegin, char* sRest) { int iLoop; char cTmp; char cFLetter[1]; char *sNewBegin; char *sCur; int iLen; static int iCount; iLen = strlen(sRest); i... 2007-02-26, 6991👍, 0💬

String Concatenation
What will be printed as the result of the operation below: main() { char *p1; char *p2; p1=(char *)malloc(25); p2=(char *)malloc(25); strcpy(p1,"Cisco"); strcpy(p2,"systems"); strcat(p1,p2); printf("%s",p1); } Answer: Ciscosystems 2007-02-26, 6837👍, 0💬

Shift Operators
What will be printed as the result of the operation below: main() { int x=5; printf("%d,%d,%d\n",x,x&lt ;<2,x>>2) ;} As x = 5 = 0x0000,0101; so x << 2 -< 0x0001,0100 = 20; x >> 2 -> 0x0000,0001 = 1. Therefore, the answer is 5, 20, 1. 2007-02-26, 6677👍, 0💬

Function Calls
What will be printed as the result of the operation below: #define swap(a,b) a=a+b;b=a-b;a=a-b; void main() { int x=5, y=10; swap (x,y); printf("%d %d\n",x,y); swap2(x,y); printf("%d %d\n",x,y); } int swap2(int a, int b) { int temp; temp=a; b=a; a=temp; return 0; } The correct answer is 10, 5 5, 10 2007-02-26, 6293👍, 0💬
