Re: [Dev-C++] regarding memory allocation

[Per W. <pw...@ia...>]

When asking for help - always attach the code you have problems with.
Right now, we don't even know if you program in C or in C++, and if you
with "floating" means the data type "float" or just floating point
numbers.

The arrays are too large to allocate as auto, i.e. on the stack.

I'm sorry, but I don't know how to create nearly 5 arrays. The code below
will manage to create exactly 5 arrays:

// float allocation in C:
#include <stdlib.h>
#include <stdio.h>

enum {
    ARRAY_SIZE = 50000,
};

int main() {
    float* array1 = (float*)malloc(ARRAY_SIZE*sizeof(*array1));
    float* array2 = (float*)malloc(ARRAY_SIZE*sizeof(*array1));
    float* array3 = (float*)malloc(ARRAY_SIZE*sizeof(*array1));
    float* array4 = (float*)malloc(ARRAY_SIZE*sizeof(*array1));
    float* array5 = (float*)malloc(ARRAY_SIZE*sizeof(*array1));
    printf("Everything allocated\n");
    return 0;
}

// double allocation in C++:
#include <iostream>

int main() {
    const int array_size = 50000;
    double *array1 = new double[array_size];
    double *array2 = new double[array_size];
    double *array3 = new double[array_size];
    double *array4 = new double[array_size];
    double *array5 = new double[array_size];
    std::cout << "Everything allocated" << std::endl;
}
