我知道这已经被问了数千次,但我只是在我的代码中找不到错误。有人可以指出我做错了什么吗?
#include <stdlib.h>
#include <string.h>
void reverseString(char *myString){
char temp;
int len = strlen(myString);
char *left = myString;
// char *right = &myString[len-1];
char *right = myString + strlen(myString) - 1;
while(left < right){
temp = *left;
*left = *right; // this line seems to be causing a segfault
*right = temp;
left++;
right--;
}
}
int main(void){
char *somestring = "hello";
printf("%s\n", somestring);
reverseString(somestring);
printf("%s", somestring);
}
