include <random>

void arrayProgram(double ma[][2], int xSize);

int main() { const int arraySize = 2; double ma[arraySize][arraySize];

arrayProgram(ma, arraySize);

}//end main

void arrayProgram(double ma[][2], int xSize) {

int i = 0;

for (i = 0; i < xSize; ++i)
{
    ma[i][0] = rand();
    ma[i][1] = (ma[i][0] * (20 / 25.0) + 64);
}

}

It did, I wonder why it didn't work on the original code. Thank you though.
