第五篇：改错题答案

改错题答案

第1题读入一个整数k(2<=k<=1000),打印它的所有质因子（即所有为素数的因子）。

第1处：IsPrime(int n);应改为IsPrime(int n)第2处：if!(n%i)应改为if(!(n%i))

第2题 fun函数的功能是:逐个比较a、b两个字符串对应位置中的字符，把ASCII值大于或相等的字符依次存放到c数组中，形成一个新的字符串。

第1处：int k=1;应改为int k=0;第2处：while(*p!=*q)应改为while(*p||*q)

第3题 fun函数的功能：是依次取出字符串中所以数字字符，形成新的字符串并取代原符串

第1处：s[j]=s[i];应改为s[j++]=s[i];第2处：s[j]=“”;应改为s[j]='';

第4题 fun函数的功能；分别统计字符串中大写字母和小写字母的个数第1处：void fun(char*s,int a,int b)应改为

void fun(char*s,int*a,int*b)第2处：a++;应改为(*a)++;第3处：b++;应改为(*b)++;第5题假定整数数列中的数不重复，并存放在数组中。第1处：a[i+1]=a[i];应改为a[i]=a[i+1];第6题计算如下公式的值 t=1-1/2*2-1/3*3-…1/m*m 第1处：for(i=2;i

void fun(char*s,char*t1,char*t2,char*w)第2处：while(r)应改为while(*r)第11题将一个由八进制数字字符组成的字符串转换为与其面值相等的十进制整数
