七题八题怎么做？

7、int main(void)
{
int i,count=0;;
int arr[100]={0};
for(i=1;i<=100;i++)
{
if((i%7==0)||(i%11==0))
{
arr[count]=i;
count++;
}
}

for(i=0;i{
printf("%d ",arr[i]);
if((i+1)%5==0)
printf("\n");
}
printf("\n");
return 0;
}
8、
void copy(char *sourceStr,char *cpyStr)
{
while(*sourceStr!='\0'){
*cpyStr=*sourceStr;
sourceStr++;
cpyStr++;
}
}

int main(void)
{
char cpyStr[10]={'\0'};
char sourceStr[10]={'\0'};
gets(sourceStr);
copy(sourceStr,cpyStr);
puts(cpyStr);
return 0;
}
