浮点指针 | imperial

本文介绍了浮点指针的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！问题描述该程序没有正确地产生和回应特别是指针（* f），（* i） in print_divide_meter_into （&米，& yds，& ft，& ins）; /*--------------pnt02own.c- ----------- --- 1英寸= 2.51厘米 --- 1英寸= 2.54 / 100米 --- 1码= 3英尺 --- 1英尺= 12英寸 ---英寸=米/ 0.0254 --- feets = meter / 0.3048（0.0254 * 12） ---码=米/ 0.9144（0.0254 * 36） ---米= 1 / 0.0254 = 39.3700英寸 ---米= 1 / 0.3048 = 3.28084 FEET ---米= 1 / 0.9144 = 1.09361 YARDS ---------------------------------------------- * / #include" stdio.h" / *模块2：使用函数中的指针将尺寸输入转换为（以米为单位）到码的大小，英尺，英寸----- * / main（） { 浮动计; float yds，ft，ins; char another（）; system（" ; cls）; 做{ input_meter（&米）; divide_meter_into（& meter，& yds，& ft，& ins）; print_divide_meter_into（& meter，& yds，& ft，& ins）; } while（another（）== ''y''）; 返回0; } input_meter（float * m） { printf（&\\; \ nEnter size in meter："）; scanf（"％f"，&（* m）） ; printf（\ n你输入％f，* m）; } divide_meter_into（浮点数） * m，float * y，float * f，float * i） { float temp_m = 0; temp_m =（* m ）* 100.0 / 2.54; （* y）=（temp_m）/36.0; （temp_m）=（temp_m） - （* y）* 36.0; （* f）=（temp_m）/12.0; （* i）=（temp_m） - （* f）* 12.0; printf （\ m Meter％f = =％f码％f英尺％f 英寸，（* m），（* y），（* f），（* i）） ; } print_divide_meter_into（float * m，float * y，float * f，浮动* i） { printf（" \ n Meter％f = =％f码％f英尺％f / / $ b） $ b inches"，（* m），（* y），（* f），（* i））; } char another another（） { 字母答案; printf（\ n你想要处理（y / n））; scanf（" \ n"）; scanf（"％c"& answer）; 返回（回答）; } That program does not yield and respond correctly espcially for thepointers (*f),(*i)inprint_divide_meter_into(&meter,&yds,&ft,&ins); /*--------------pnt02own.c---------------1 inch = 2.51 cm---1 inch = 2.54/100 Meter---1 yard = 3 feet---1 feet = 12 inch---inches=meter/0.0254---feets =meter/0.3048 (0.0254 * 12)---yards =meter/0.9144 (0.0254 * 36)---meter=1/0.0254=39.3700 INCH---meter=1/0.3048=3.28084 FEET---meter=1/0.9144=1.09361 YARDS----------------------------------------------*/#include "stdio.h"/*Module 2 : using pointers in a function to convert Size Entryin meter to sizes of Yards,feet,inches-----*/main(){float meter;float yds,ft,ins;char another();system("cls");do {input_meter(&meter);divide_meter_into(&meter,&yds,&ft,&ins);print_divide_meter_into(&meter,&yds,&ft,&ins);} while (another()==''y'');return 0;} input_meter(float *m){printf("\nEnter size in meter :");scanf("%f",&(*m));printf("\nYou have Entered % f",*m);} divide_meter_into(float *m,float *y,float *f,float *i){float temp_m=0;temp_m=(*m)*100.0/2.54;(*y)=(temp_m)/36.0;(temp_m)=(temp_m)-(*y)*36.0;(*f)=(temp_m)/12.0;(*i)=(temp_m)-(*f)*12.0;printf("\n Meter %f is = %f yards %f feet %finches",(*m),(*y),(*f),(*i));} print_divide_meter_into(float *m,float *y,float *f,float *i){printf("\n Meter %f is = %f yards %f feet %finches",(*m),(*y),(*f),(*i));} char another(){char answer;printf("\n do ou want to procees (y/n)");scanf("\n");scanf("%c",&answer);return (answer);} 推荐答案再次不必要的括号马克麦金太尔 - ---- ==通过Newsfeeds.Com发布 - 无限制 - 无限制安全Usenet新闻== ---- http：//www.newsfeeds .com 世界排名第一的新闻组服务！ 120,000多个新闻组 ---- =东海岸和西海岸服务器农场 - 通过加密实现全隐私= ---- again unneccessary brackets Mark McIntyre-- ----== Posted via Newsfeeds.Com - Unlimited-Unrestricted-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups----= East and West-Coast Server Farms - Total Privacy via Encryption =---- 这是什么意思？你期望它做什么？实际上是什么呢？呢？我们不介意读者。 Brian - 请为上下文引用足够的上一条消息。要从 Google执行此操作，请点击显示选项。并使用展开的标题中显示的回复。 What does this mean?
