计算机二级考试 C语言

五、1、#include <stdio.h>

int min(int a,int b){

return (a<b?a:b);

} void main(){

int a,b;

scanf(“%d,%d”,&a,&b);

printf(“%d”,min(a,b)); }

2. #include <stdio.h>

void main(){

float score[10][5], stuave[10],courseave[5],fangcha;

float temp1,temp2;

int i,j;

printf(“Please input the scores :”);

for (i=0;i<10;i++){

stuave[i]=0; temp1=0; temp2=0;

for (j=0;j<5;j++){

scanf(“%f”,&a[i][j]);

stuave[i]+=a[i][j];

}

stuave[i]/=5.0; temp1+=stuave[i]*stuave[i]; temp2+=stuave[i];

}

for (j=0;j<5;j++){

courseave[j]=0;

for (i=0;i<10;i++)

courseave[j]+=score[i][j];

courseave[j]/=10.0;}

fangcha=temp1/n-(temp2/n)*(temp2/n);

printf(“the average scores of each student are: ”); for (i=0;i<10;i++) printf(“%5.2f”,stuave[i]); printf(“the average scores of each course are: ”); for (i=0;i<5;i++) printf(“%5.2f”,courseave[i]); printf(“the fangcha is %5.2f”,fangcha);

}

3、非递归方法

#include <stdio.h>

void main(){

int n,i=0;

long fac=1;

scanf(“%d”,&n);

while (i<n){

i++; fac*=i;

}

printf(“%ld”,fac);
