C语言函数习题及答案(14)

int a[N],c[M2-M1+1]={0},i,n=0,x=0;

printf("Please input a sequence of number(%d-%d) which is ended with

-1:\n",M1,M2);

while(x!=-1)

{

scanf("%d",&x);

a[n]=x;

n++;

}

f(a,c,n);

printf("Repeating times of %d-%d in sequence of number is:\n",M1,M2);

for(i=0;i<=M2-M1;i++)

printf(“%d:%d\n”, 【1】);

printf("\n");

}

f(【2】)

{

int i;

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

if(a[i]>=M1 && a[i]<=M2)

【3】;

}

【1】A）M1+i:c[M1+i] B）M1+i+1:c[i]

C）M1+i:c[i] D）i:c[M1+i]

【2】A）f(a[],c[],n) B）f(int a[],int c[],int n)

C）f(a,c,n) D）f(int a[N],c[M2-M1+1],n)

【3】A）c[a[i]]++ B）c[a[i]-M2]++

C）a[c[i]]++ D）c[a[i]-M1]++

二．读程序写结果

1.

fun(int x,int y,int z)

{

z =x*x+y*y;

}

main ( )

{

int a=31;

fun (6,3,a);

printf ("%d", a);

}

2.

int f( )

{
