Question

I have a project that requires different types of iterations. One is function recursion on a char array of 5000. After 50 calls it will crash, assuming from stack overflow. Not sure how to get around this.

void functionLoop(int loopInt)
{
#ifdef ___EXSTR_H___
#undef ___EXSTR_H___
#endif
#include "exstr.h"

    ofstream fout;
    fout.open("output.txt");

    int arrayLength =  sizeof ( example_strings ) / 4; // arrayLength = 5000.
    char *stringArray = example_strings[loopInt];
    int charCount = 0;
    while( *stringArray != 0 )
    {
        stringArray++;
        charCount++;
    }
    cout << loopInt + 1 << ": " << charCount << ": " << example_strings[loopInt] << endl;
    loopInt++;
    if(loopInt < arrayLength)
    {   
        functionLoop(loopInt);      
    }
}

EDIT:

I cleaned up the code a lot, got rid of all the variables, moved the header file to a parameter, and gained about 4500 more iterations, but it’s still crashing after 4546. Here’s the updated code:

void functionLoop(char * example_strings[], ofstream &outputFile, int counter)
{     
    outputFile << counter + 1 << ": " << strlen(example_strings[counter]) << ": " << example_strings[counter] << endl;
    counter++;

    if(counter < ARRAY_SIZE)
    {   
        functionLoop(example_strings, outputFile, counter);      
    }
}

Thank you to everyone that helped.

Pass the array as a parameter to your function, i.e.

printLoop(outputFile, example_strings, current_index, max_index);
