13 Write a function definition for a function called oneMore, which has a formal parameter for an array of integers and increases the value of each array element by 1 Add any other formal parameters that are needed

14 Consider the following function definition:

void too2(int a[], int howMany) { for (int index = 0; index < howMany; index++) a[index] = 2; }
