c++ - Use struct and recursion to find the largest number in an integer array -


i'm required use recursion find largest number in integer array. also, need both value , index of largest number. used "struct" gave me weird number , cannot figure out why.

here's struct:

struct maxnumber {     int index;     int value; };

here's find_largest function:

maxnumber numbers::find_largest()  {       maxnumber max;        int current ;//keep track of current counter        if(size == 1)       {           max.value = numarray[0];           max.index = 0;           return max;       }        if(current < size && size != 0)  //loop through numbers in array       {           if(numarray[current] >= max.value)            {             max.value = numarray[current];             max.index = current;            }         current++;        find_largest();        }          return max;  }

then, in main function, did this:

int result = num.find_largest().value; cout << "the largest number " << result << endl;

however, gives me large number. need figure out what's wrong.

your main problem current has local storage , reallocated on every call findlargest. change declaration this

static int current = 0;

and should work, if size , numarray defined elsewhere in class definition.

but same thing happening more subtly max, , should declared statically well.
