格式化文本，在字符串两头加入特定字符

#include <string.h>#include <stdio.h>void main(int argc, char *argv[]){int len = 0;char chr[102];char tmp[102] = "/"";char tmp2[102] = "/0";FILE *fp,*fp2;//char *fname;if ((fp = fopen(argv[1],"r")) == NULL){printf("open test.txt fail!/n");}if ((fp2 = fopen("result.txt", "w")) == NULL){printf("open result.txt fail!/n");}while(!feof(fp)){fgets(chr, 100, fp);if (strcmp(chr, "/n") == 0 || strcmp(chr,"") == 0){continue;}else{strtok(chr, "/n");strcat(chr, "/",");strcat(tmp, chr);printf("%s/n",tmp);fputs(tmp, fp2);fputs("/n", fp2);//strcpy(chr, tmp2);strcpy(tmp, tmp2);strcpy(tmp, "/"");}}}
