Problems 13
  1. Theory.
    1. Will the following function leak memory? 
      double bar(int n){
	double* x = (double*)malloc(n*sizeof(double));
	/* do staff with x */
	return x[0];
	free(x);
}
  2. Practice.
    1. Debug somebody else's project here.
      • Assume that the assignment was the following: "build a function that prints half the [0,0] element of a given matrix".
      • You shouldn't rewrite the code, you should only correct the errors --- if any --- in the Makefile and the code.
