I'm trying to pass a character array as a parameter, and I need to check to make sure that it's passed alright (i pass the pointer and then the length). When I debug through it, the variable watcher only shows the first character. Does anyone know how I can view, or walk through the character array so i can verify the contents?

I think this isn't a real C++ issue. You could add debug code to the function to print the array, I suppose. Can't you use std::string instead?
Code:#include <stdio.h> void J(char*a){int f,i=0,c='1';for(;a[i]!='0';++i)if(i==81){ puts(a);return;}for(;c<='9';++c){for(f=0;f<9;++f)if(a[i-i%27+i%9 /3*3+f/3*9+f%3]==c||a[i%9+f*9]==c||a[i-i%9+f]==c)goto e;a[i]=c;J(a);a[i] ='0';e:;}}int main(int c,char**v){int t=0;if(c>1){for(;v[1][ t];++t);if(t==81){J(v[1]);return 0;}}puts("sudoku [0-9]{81}");return 1;}
There are all sorts of alternate formats you can add to your variables, especially pointers.
In the watch window, edit the var to be
myCharPointer,10
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
thankyou salem, that's exactly what i was looking for
