如何读取字符串

[singleperson]

怎么能读取一个字符串的后两位

[liguoqiang19780406]

#include <stdio.h>
#include <string.h>

int main(int argc, char *argv[])
{
char str[] = "this is a char array.";
char substr[3];
int startPoint = strlen(str) - 2;
memcpy(substr, str + startPoint, 2);
substr[2] = '\0';
printf("str= %s\nsubstr =%s\n", str, substr);
return 0;
}

[TianGuangZao]

#include <stdio.h>

int main()
{
char str[] = "abcdef";
int len = strlen(str);
printf ("%s\n", str+len-2);

return 0;
}

你把指针移到字符串的倒数第二个字母即可

找到倒数第二个位置就可以了，方法多了

#include <string.h>
#include<iostream.h>
main()
{
char a[20]="afadlfsadfewuw";
char *p=a;
p=p+strlen(a)-2;
cout<<p;
}
