HW 9/12/2018 1. Generate a table of conversions from feet per second to miles per hour. Start the ft/s column at 0 and increment by 5 ft/s. The last line should contain the value 100 ft/s. (Recall that 1 mi = 5280 ft)    #include < stdio.h > #include< math.h > #define PI 3.141593 int main( void ) {      double ft_s= 0 ;       double mi_h;          printf( "ft/s       to    mi/h \n" );          while (ft_s <= 100 )           {   mi_h = ft_s* 0.681 ;            printf( "%8.2f       %6.4f \n" ,ft_s,mi_h);             ft_s += 5 ;  }      ...
