编写函数,用递归法计算x的n(n>=0)次方

#includefun(intx,intn){if(n==0)return(1);elsereturn(x*fun(x,n-1));}main(){intx,n;scanf("%d,%d",&x,&n

你应该定义成doublegetPower(doublex,inty)就可以了目前你的定义的情况下getPower(b,m)找不到最匹配的就是(double,int)只能找次匹配的,找到了(double

#includelongintfn(int);voidmain(){printf("%d",fn(10));}longintfn(intm){longinttemp;if((1==m)|(2==m))

很高兴回答你的问题!#includeintfun(intn,intx){if(n==0)return1;intmul=x;for(inti=n;i>1;i--)mul*=x;returnfun(n-1

longpower(intm,intn){doublep=1;if(n>0){p=m*power(m,(n-1));returnp;}}voidmain(){intm,n;longk;scanf("%

#includedoubleH(intn,doublex){if(x>1){if(n==0)return1.0;//H0(x)=1;if(n==1)return2.0*x;//H1(x)=2x;//直

intfunc(intx,intn){inty;if(n

#includeintFibonacci(intn){if(n==1||n==2)//递归结束的条件,求前两项return1;elsereturnFibonacci(n-1)+Fibonacci(n-

#includelongfac(intn){inti;longx=1;for(i=2;i再问：谢谢咯！可是我说的是递归法哦！再答：#includelongfac(intn){if(n==0)retur

fun函数是double类型的,而返回的y是int类型,二者不匹配,将y强制为double类型就可以了

程序已经调试过了,你看下吧,可以的话给个好评#include"iostream"usingnamespacestd;floatpower(floata,intn){if(n==1)returna;el

C描述functionttt(n){ returnn>1?n*ttt(n-1):1;}使用方法:ttt(21);

f函数里已经被传进一个参数值了为什么还要再输入一个n值呢?另外,n前还要加&,应该是scanf("%d",&n);

#includedoublepow(doublex,intn){if(1==n){returnx;}else{doubletemp=pow(x,n-1);return(x*temp);}}voidma

longmi(intx,intn){if(n=1)returnn;elsereturn((long)x*mi(x,n-1);}

#includemain(){intn,i,j,k;while(scanf("%d",&n)==1){if(n==1||n==2){printf("%d\n",1);cont

if(n==1)\x05\x05return1;你可以改成n==0或者改成returnx取其中一种就可以了

#includedoublef(doublex,intn){if(n==1)returnx;else{doubled=1.0;inti;for(i=1;i
