Value return by a method does not change???
Hi this is my simple c++ programme, it has Thermister class which calculate resistance when varying Temp,but each time when calling to setTemp() eventhough it change value of Temp,value given by getResistance() mthd does not change.It always gives 1 when calling through a for loop.here is the code any help please...... -

Decripting does not happen properly.
this programme is to encripta text with a key and decript that text again into real language.but the matter is when I enter text "attack the base" and the word "kill" as the key and decript the text with the same key"kill",outpu t is only "a",why it dose not print all the text?is it due to global variable a[]?could u please help me?...Code:#include<stdio.h> #include<stdlib.h> char a[100]={'\0'},key[4]; -

recursive functions with arrays as parameters
I wrote a fuction in C with the prototype

But it seems that this function doesn't give the exact answer
And I tried this from java also,with... -
