6.编写一个程序，实现将c语言源程序中的注释全部删除
#include<stdlib.h>#include<stdio.h>#include<string.h>int main(){FILE *fp,*fp1;char str[99]="",str1[99]="";int i,j,no=0;if((fp=fopen("file1.c","r"))==NULL){printf("error\n");exit(0);}if((fp1=fopen("new.c","w"))==NULL){printf("error\n");exit(0);}while(fgets(str,99,fp)!=NULL){for(i=0;i<99;i++){if(str[i]=='/' && str[i-1]=='/'){str[i-1]='\n';str[i]='\0';}if(str[i]=='*' && str[i-1]=='/'){str[i-1]='\0';no=1;fputs(str,fp1);}if(str[i]=='/' && str[i-1]=='*'){for(j=0;j<98-i;j++){str[j]=str[i+j+1];str[j]='\0';no=0;}}}if(no==0){fputs(str,fp1);}}fclose(fp);fclose(fp1);return 0;}
