To do: Calculating an area for the given width and length C++ code sample demonstrating user defined function
To show: How to calculate an area for the given width and length C++ program example to show the user defined function
// demonstrates the use of function prototypes
#include <iostream>
// another method simplifying type identifier using typedef
// the words unsigned short is simplified to USHORT
typedef unsigned short USHORT;
// function prototype
USHORT FindTheArea(USHORT length, USHORT width);
int main(void)
{
USHORT lengthOfYard;
USHORT widthOfYard;
USHORT areaOfYard;
std::cout<<"\nThe wide of your yard (meter)? ";
std::cin>>widthOfYard;
std::cout<<"\nThe long of your yard( meter)? ";
std::cin>>lengthOfYard;
// function call
areaOfYard = FindTheArea(lengthOfYard, widthOfYard);
std::cout<<"\nYour yard is ";
std::cout<<areaOfYard;
std::cout<<" square meter\n\n";
return 0;
}
// function definition
USHORT FindTheArea(USHORT l, USHORT w)
{
return (l * w);
}
Output example:
The wide of your yard (meter)? 10
The long of your yard( meter)? 21
Your yard is 210 square meter
