Right YOU are – robert alias “java the hood”

If you program C and define an N-dimensional !static! array, an one dimensional array will be used instead.

What I’d say is that if you want to use an N-dimensional access to an array of values, you have to allocate the data in this way:


// a will be 2-dimensional 20x10
double** a=(double**)malloc(20*sizeof(double*));
for (i=0;i<20;i++)
a[i]=(double*)malloc(10*sizeof(double));


Then you can access a in the 2-dim way a[i][j] instead of computing the index of your own a[i*10+j]. This on the other hand won’t work any more.

If you’d define the array statically without a malloc, you can use both
a[i][j] as well as a[i*10+j], since it’s an one dimensional field internaly
