倒置字符串s中各字符的位置

void reverse(char s[]){
int c,i,j;
for(i=0,j=strlen(s)-1;i<j;i++,j--){
c=s[i], s[i]=s[j], s[j]=c;
}
}

#include <stdio.h>
#include <string.h>
void reverse(char s[]){
int c,i,j;
for(i=0,j=strlen(s)-1;i<j;i++,j--){
c=s[i];
s[i]=s[j];
s[j]=c;
}
}
int main(){
char s[]="abc";
reverse(s);
printf("%s\n",s);
getchar();

return 0;
