全国计算机等级考试四级计算机编程题

第一集

===============================================================================

试题描述:

===============================================================================

已知有几个(数量

Number,函数ReadDat()读取这些正整数,并将它们存储在数组xx中。请

编译函数CalValue(),其函数要求为:1。找出这个文件中* * *有多少。

正整数totNum2.找出数字总和为奇数的数字。

满足这个条件的数totCnt和这些数的算术平均值totPjz,最

之后,调用函数WriteDat()将所需结果输出到文件OUT1.DAT。

注意:部分源程序存储在PROG1中。C

不要改变主函数main(),读取数据函数ReadDat()和输出数据。

函数WriteDat()的内容。

===============================================================================

程序:

===============================================================================

#包括

#包括

#定义最大数量200

int xx[MAXNUM];

int tot num = 0;/* IN的文件中有多少个正整数* *个。DAT * *

int tot CNT = 0;/*合格正整数的个数*/

double totPjz = 0.0/*平均值*/

int read dat(void);

void WriteDat(void);

空CalValue(空)

{

}

void main()

{

clr SCR();

if(ReadDat()) {

Printf("数据文件在。DAT无法打开!\ 007 \ n ");

返回;

}

CalValue();

Printf ("* *在。DAT有正整数=%d \n”,totNum);

Printf("合格正整数的个数=%d \n ",tot CNT);

Printf ("average =%.2lf\n ",totPjz);

write dat();

}

int ReadDat(void)

{

FILE * fp

int I = 0;

if((fp = fopen("in.dat "," r ")= = NULL)返回1;

而(!feof(fp)) {

fscanf(fp," %d,",& ampxx[i++]);

}

fclose(FP);

返回0;

}

void WriteDat(void)

{

FILE * fp

fp = fopen("OUT1。DAT”、“w”);

fprintf(fp," %d\n%d\n%.2lf\n ",totNum,totCnt,totPjz);

fclose(FP);

}
