1、请编制递归函数fabonacci(),此函数用来求斐波那契数列的第n项？ #include <stdio.h> int fib(int n) { if(n<=2) return(1); else return(fib(n-1)+fib(n-2)); } void main() { int n; do { printf("\nInput n(1-40):\n"); scanf("%d",&n); }while(n<=0||n>40); printf("\nThe result is:%ld\n",fib(n)); } 2、编制函数min(),求三个小数的最小值？ #include <stdio.h> float min(float,float,float); void main() { float a,b,c; printf("Input a b c:"); scanf("%f%f%f",&a,&b,&c); printf("Minimum number is:%f",min(a,b,c)); } float min(float a,float b,float c) { if(a<b) if(a<c) return a; else return c; else if(b<c) return b; else return c; }
