#include <iostream>


int WidthInFeet();
int WidthInInches(int feet);



int main()
{

int feet = WidthInFeet();
int wd = WidthInInches(feet);***************************


std::cout << "Width in inches = " << wd;

return 0;
}


int WidthInFeet()
{
int feet;

std::cout << "Enter width in feet: ";
std::cin >> feet;

return feet;
}

int WidthInInches(int feet)
{
return feet * 12;
}


why 很多星那一行的(feet) 不可是(int feet) ?

畢竟其他 feet 都有 int 在前面,3Q LZ !
