1、C0扩充文法编译器测试报告模板C0扩充文法编译器测试报告学号：_37230118_姓名：_罗杨_2010年 1月 16日 1测试样例一（正确）测试样例int fib(int k) if (k=0) return (1); if (k=1) return (1); return (fib(k-1)+fib(k-2);void main() int n,result; printf(Please enter n: ); scanf(n); printf(Fib(n) is: ); result=fib(n); printf(result); return ;程序输出输入一个数字，输出其斐波那契数目
