Question

Pressure on an object is given by forceApplied/contactArea. Write a program that reads double variables forceApplied and contactArea from the input, respectively, and computes objectPressure using the formula. Then, outputs "Object pressure is " followed by the value of objectPressure to four digits after the decimal point. End with a newline.

Ex: If the input is 1.25 2.0, then the output is:

Object pressure is 0.6250

Answer 1

// Use at least C++11 when compiling

#include // Needed for input output operations
#include // for 4 decimal places
#include // for converting input from string to decimal stod()
int main (int argc, char* argv[])
{
double forceApplied = std::stod(argv[1]);
double contactArea = std::stod(argv[2]);

double pressure = forceApplied/contactArea;

std::cout << “Object pressure is “ << std::fixed << std::setprecision(4) << pressure << “\\”;

return 0;
}
