basicpp 介绍
basicpp 使得今天的 C 可以像 80 年代的 BASIC 语言一样的简单。该项目在了 C 中实现了简单的 BASIC 仿真。
示例代码：
#include "basic.hpp"
int main()
{
_10: LET X = 1;
_20: LET SUM = 0;
_30: LET DEPTH = 1;
_40: INPUT "Enter a positive number: ", X;
_50: IF X > 0 THEN GOTO _130;
_60: PRINT "By positive, I mean greater than zero. You entered ", X, " which isn't";
_70: GOTO _40;
_80: SUM = SUM + X;
_90: X = X - 1;
_100: IF X > 0 THEN GOSUB _80;
_110: DEPTH = DEPTH * 2;
_120: RETURN;
_130: GOSUB _80;
_140: PRINT "SUM=", SUM, " DEPTH=", DEPTH;
}
