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; }
