Question

a) Write a program in c++ has a declaration in main() to store the following numbers into an array named rates: 6.5, 7.2,7.5, 8.7, 8.6,9.4,9.6,9.8,10.6. There should be a function call to show()that accepts rates in a parameter argument named rates and then displays the numbers using the pointer notation: *(rates+i) (use cin/cout if needed)

b) Modify the show() function written above to alter the address in rates. Always use the expression *rates rather than *(rates+i)to retrieve the correct element.

Answer 1

Answer 1:

#include <iostream>

using namespace std;
void show(double *arr){
for(int i=0;i<9;i++)
cout<<*(arr+i)<<" ";
}
int main()
{
double arr[]={6.5, 7.2,7.5, 8.7, 8.6,9.4,9.6,9.8,10.6};
show(arr);

return 0;
}

#include <iostream> using namespace std; void show (double arr) { for(int i=0;i<9;i++) cout< < (arr+i)<<" "; w int main() double arr[] {6.5, 7.2,7.5, 8.7, 8.6,9.4,9.6,9.8, 10.63 show(arr); return 0; 6.5 7.2 7.5 8.7 8.6 9.4 9.6 9.8 10.6 ...Program finished with exit code 0 Press ENTER to exit console.

Answer 2:

#include <iostream>

using namespace std;
void show(double *rates){
for(int i=0;i<9;i++,rates++)
cout<<*rates<<" ";
}
int main()
{
double arr[]={6.5, 7.2,7.5, 8.7, 8.6,9.4,9.6,9.8,10.6};
show(arr);

return 0;
}

9 include <iostream> 10 using namespace std; 12. void show (double rates) { 13 for(int i=0;i<9;i++,rates++) 14 cout<< rates<<" "; 16 int main() 17 - { double arr[] {6.5, 7.2,7.5, 3.7, 8.6,9.4,9.6,9.8,10.6}; show(arr); return ; 6.5 7.2 7.5 8.7 8.6 9.4 9.6 9.8 10.6 ...Program finished with exit code 0 Press ENTER to exit console.]
