字符串问题
void *mymemset(char *dest, char c, size_t count)
{
int sum = 0;
for(;*dest != 0;++dest)
{
sum++;
}
if(sum < count)
return 0;
for(int i = 0; i<count;++i)
{
dest[i] = c;
}

}


int main()
{
char array1[] ="sdaffgfgdfdsfdsfdfdfdf";

mymemset(array1,'e', 6);
cout << array1<<endl;

return 0;
}
练习下，但是出错了 //将dest前面count个字符置为字符c. 返回dest的值
请 帮我 看看，谢谢啦

[解决办法]

C/C++ code

#include<iostream>using namespace std;char *mymemset(char *dest, char c, size_t count){ int sum = 0;char *p=dest;for(;*p!= '\0';++p){sum++;}  if(sum < count)return 0;for(int i = 0; i<count;++i){dest[i] = c;}return dest;}int main(){char array1[] ="sdaffgfgdfdsfdsfdfdfdf";mymemset(array1,'e', 6);cout << array1<<endl;        system("pause");    return 0;}
