working of incr/decr operator:first pre operators then rest of opera

main()
{int i=5; // line 1
i=(++i)/(i++); // line 2
printf("%d",i); // line 3
} output is 2 but if we replace line 2 and line 3 by
printf("%d",i=(++i)/(i++)); then output is 1. Why?

Answer Posted / gagandeep bansal

working of incr/decr operator:first pre operators then
rest of operators then post operators

so,2 line become:i=6/(5++); /*pre operator*/
i=6/5=1; /*rest of operators*/
now post incr operator will work so,i=2; /*post operator*/
so output is 2.
in second case:i=6/(5++); /*pre operator*/

i=6/5==1; /*rest of operators*/

now post incr operator will work so,i=2;
again i=3/(2++);
i=1;
so,output is 1.
becouse in case of post operators first assign then
incr/decr.

You have given 2 array. You need to find whether they will create the same BST or not. For example: Array1:10 5 20 15 30 Array2:10 20 15 30 5 Result: True Array1:10 5 20 15 30 Array2:10 15 20 30 5 Result: False One Approach is Pretty Clear by creating BST O(nlogn) then checking two tree for identical O(N) overall O(nlogn) ..we need there exist O(N) Time & O(1) Space also without extra space .Algorithm ?? DevoCoder guest Posted 3 months ago # #define true 1 #define false 0 int check(int a1[],int a2[],int n1,int n2) { int i; //n1 size of array a1[] and n2 size of a2[] if(n1!=n2) return false; //n1 and n2 must be same for(i=0;ia1[i+1]) && (a2[i]>a2[i+1]) ) ) return false; } return true;//assumed that each array doesn't contain duplicate elements in themshelves }

write an interactive C program that will encode or decode a line of text.To encode a line of text,proceed as follows. 1.convert each character,including blank spaces,to its ASCII equivalent. 2.Generate a positive random integer.add this integer to the ASCII equivalent of each character.The same random integer will be used for the entire line of text. 3.Suppose that N1 represents the lowest permissible value in the ASCII code,and N2 represents the highest permissible value.If the number obtained in step 2 above(i.e.,the original ASCII equivalent plus the random integer)exceeds N2,then subtract the largest possible multiple of N2 from this number,and add the remainder to N1.Hence the encoded number will always fall between N1 and N2,and will therefore always represent some ASCII character. 4.Dislay the characters that correspond to the encoded ASCII values. The procedure is reversed when decoding a line of text.Be certain,however,that the same random number is used in decodingas was used in encoding.
