scanf等效于c中的箭头键支持

c中是否有一些函数表现得像scanf（从键盘输入），同时能够通过按箭头键在输入中移动光标，就像在终端中一样？

Answer 1

C标准中没有function可以做到这一点。

你可以看看ncurses

Answer 2

除了以前的建议，如果你想做一些工作，你可以使用vt100转义序列“自己动手”，大多数（可能是所有）终端程序都会继续支持。 这是一个小样本程序，

#include  #include  #include "vt100.h" int main ( int argc, char *argv[] ) { char cupstr[99]; char reply[99]; strcpy(cupstr,_cup(12,25)); printf("%sEnter Data ---> ",cupstr); fgets(reply,88,stdin); strcpy(cupstr,_cup(13,25)); printf("%sEchoed Data --> %s\n",cupstr,reply); } 

最重要的是vt100.h包含所有转义序列，

 /* ------------------------------------------------------------------------- * VT100.H (c)1989-1999, John Forkosh Associates VT-100 Graphics * ------------------------------------------------------------------------- */ #define bel printf("\007") #define esc printf("\033") #define csi printf("\033[") #define lscreen printf("\033[?5h") #define dscreen printf("\033[?5l") #define rev_vid printf("\033[7m") #define blink printf("\033[5m") #define under printf("\033[4m") #define bold printf("\033[1m") #define norm_vid printf("\033[0m") #define wide_vid printf("\033#6") #define high_vid2 printf("\033#4") #define high_vid1 printf("\033#3") #define graphic printf("\033(0") #define no_graph printf("\033(B") #define no_window printf("\033[1;24r") #define no_att printf("\033[0;22;24;25;27m") #define cup(row,col) printf("\033[%d;%dH",(row),(col)) #define stbm(top,bot) printf("\033[%d;%dr",(top),(bot)) #define ri printf("\033M") #define el printf("\033[K") #define ed0 printf("\033[0J") #define bar graphic;printf("x");no_graph #define wipe(row,col) cup(row,col);printf("\033[J") #define clr wipe(0,0);norm_vid /* ------------------------------------------------------------------------- * String equivalents ...

这些转义序列让你可以在很久很久以前对vt100，vt220等所有以前看起来很酷的东西进行编程（但就在这个星系中）。
