Question

can someone change this code so that timestandard can be calculated at the end of the code using the inputs n,RF,PFD, and the measured cycles, instead of being called from the beginning of the code

using namespace std;

float timestandard(float time, float rf, float pfd)

{

return((time / 100) * rf * (1 + pfd)); /* calculating the time standard using the given formula*/

}

int main()

{

int n, rf, pfd, x;

/* inputs are taken*/

cout << "**** Welcome to the Time Study Program ****";

cout << "\nEnter the number of operations for the given operation being performed";

cout << "\nNumber of elements:";

cin >> n; // Input for # elements

cout << "\n\nEnter the Performance Rating<PR> factor as a percentage";

cout << "\nRF:";

cin >> rf; // Input for PR

cout << "\n\nEnter the Personal Fatigue Delay<PFD> value as a percentage";

cout << "\nPFD:";

cin >> pfd; // Input for PFD

cout << "\n\nNow enter the measured cycle times in hundreths of a minute for each element";

for (int i = 0;i < n;i++) // Input for each measured cycle

{

cout << "\nElement " << i + 1 << ": ";

cin >> x;

}

/*rest of the calculation and function calling is done here*/

float r = (float)rf / 100;

float p = (float)pfd / 100;

cout << "\n\n**** Time Study Results ****";

cout << "\nThe Time Standard is: Ts = " << timestandard(x, r, p) << " minutes";

return 0;

}
