用C语言怎么实现复制自己

#include <stdio.h> #include <string.h> int main(int argc, char *argv[]) { char str[80]; int i = 0; for(i = 0; i < 5; i++) { sprintf(str, "cp %s %d%s", argv[0], i, ".out");  //在WIN下用copy取代cp system(str); } //printf("%s\n", str); return 0;

}

下边是自己动手写的copy函数

#include <stdio.h> #include <stdlib.h> #include <string.h> void copy_file(char *SrcFileName, char *DesFileName) {char buf[1024];int read_len = 0;FILE *in = NULL;FILE *out = NULL;if((in = fopen(SrcFileName, "rb")) == NULL){printf("Open %s failure.\n", SrcFileName);exit(1);}if((out = fopen(DesFileName, "wb")) == NULL){printf("Open %s failure.\n", SrcFileName);exit(1);}while((read_len = fread(buf, sizeof(char), 1024, in)) != 0) {fwrite(buf, sizeof(char), read_len, out);}fclose(in);fclose(out); } int main(int argc, char *argv[]) {char str[80];int i = 0;char *find_result;for(i = 0; i < 5; i++){sprintf(str, "%d%s", i, ".out");find_result = strrchr(argv[0], '/');if (strcmp(str, find_result + 1) !=0 ){copy_file(argv[0], str);}}printf("%s\n", str);return 0; }
