Write a code that does the following: ( C program )  /* vector_sum(V, vector_size) Given a vector V and its size, return the sum of all elements of V. Do not modify any elements of the input vector V. */ double vector_sum(Vector V, int vector_size); /* dot_product(V1, V2, vector_size) Given two vectors V1 and V2, along with their size (which is assumed to be the same for both input vectors), return the dot product of V1 and V2. Do not modify any elements of the input vectors V1 and V2. */ double dot_product(Vector V1, Vector V2, int vector_size); /* norm(V, vector_size) Given a vector V and its size, return the norm (length) of V. Recall that the length of a vector V is the square root of the dot product of V with itself. Do not modify any elements of the input vector V. */ double norm(Vector V, int vector_size);
