c语言编程题及答案，c语言笔试题及答案

1，c语言笔试题及答案我就把主程序写给你啊main（）int x;long int f;printf("Please input x: ");if(x>0)f=2x-1;else if(x=0)f=-7909;elsef=-5x+27;printf("F(x)=%ld",f);}还有你说的图一根本看不到、、
2，c语言编程题答案#include <stdio.h>int Fib (int n);//函数声明void main (){ int i,n; printf ("input the n: "); scanf ("%d",&n); printf ("斐波契数列的前%d项为:\n",n);//输入项数 for (i=0;i<=n;i++) printf ("%d ",Fib (i)); printf ("\n");}int Fib (int n){ if (n==0||n==1) return 1; return Fib(n-2)+Fib(n-1);}
3，C语言编程题求答案#include <stdio.h>int main(void) int number[8],num[3][3],i,j,k = 0,temp; printf("请将1~8打乱输入\n"); for(i = 0;i < 8;i++) scanf("%d",&number[i]); }printf("你输入的：\n"); for(i = 0;i < 3;i++)for(j = 0;j < 3;j++)if(i == 1 && j == 1)printf("");continue;}elseprintf("%d",number[k++]);}printf("\n"); }for(i = 0;i < 7;i++)for(j = 0;j < 7 - i;j++)if(number[j] > number[j + 1])temp = number[j];number[j] = number[j + 1];number[j + 1] = temp;}} }k = 0; for(i = 0;i < 3;i++)for(j = 0;j < 3;j++)if(i == 0)num[i][j] = number[k++];}else if(i == 1)if(j == 0)num[i][j] = number[7];else if(j == 1)continue;elsenum[i][j] = number[k];k += 3;}}elsenum[i][j] = number[k--];} } printf("运行后的：\n"); for(i = 0;i < 3;i++)for(j = 0;j < 3;j++)if(i == 1 && j == 1)printf("");elseprintf("%d",num[i][j]);}printf("\n"); } return 0;}【c语言编程题及答案，c语言笔试题及答案】
