反转字符串（c语言）

简单的反转字符串实现

#include <stdio.h>

#include "string.h"

void exchange(char *string, int c1, int c2);

void revertString(char *string, int iStart, int iEnd);
int main(int argc, const char * argv[])

{
// insert code here...

    printf("Begin>>>!\n");
char originalString[100] = "abcdef";

    printf("%s\n", originalString);

    size_t len = strlen(originalString);

    revertString(originalString, 0, (int)(len-1));

    printf("%s\n", originalString);
return 0;

}
void revertString(char *string, int iStart, int iEnd)

{

    while (iStart < iEnd) {

        exchange(string, iStart, iEnd);

        iStart++;

        iEnd--;

    }

}
void exchange(char *string, int c1, int c2)

{

    char tmp = string[c1];

    string[c1] = string[c2];

    string[c2] = tmp;

}
