Question

Finish the following functions (in C language):

1. void vector_input(float v[],int n): input the elements of vector v and store in the

array. (15 points)

2. void vector_output(float v[],int n): output the elements of vector v on the screen.

(15 points)

3. void vector_add(float v1[],float v2[],float v3[],int n): calculate the sum of vector v1

and v2 and store the result in v3. The sum is a vector, not a single value. (20

points)

4. void vector_multiply(float v[],int n,float x): multiply each element in v by x (15

points)

5. float inner_product(float v1[],float v2[],int n): return the inner product of vector v1

and v2. (20 points)

6. float length(float v[],int n): return the length of vector v (15 points)
