remove comments
Here is the program.This is to remove comments from a program source code.THe program does not work properly.I can't figure out why?help!!!!
#include <stdio.h>
#include <string.h>
void removeComments(char pro[]){
int i=0,j=0,len=0,newLen=0;
char newPro[1000];
printf("Hi");
len = strlen(pro);
printf("length = %d",len);
printf("%d",len);
while(i<len){
if((pro[i] == '/')&&(pro[i+1]=='*')){
i = i+2;
while(!((pro[i+1]=='*')&&(
i++;
i += 2;
}
newPro[j] = pro[i];
j++;
i++;
}
j=0;
newLen = strlen(newPro);
while(j<newLen)
printf("%s",newPro[j]);
}
void main(){
void removeComments(char c[]);
char length,line[50],myPro[1000
int k = 0,n=0;
printf("Enter your program\n");
scanf("%s",line);
while(line[0] != '0'){
length = strlen(line);
printf("%d",length);
while(n<length)
myPro[k++]=line[n++];
scanf("%s",line);
}/*end while*/
for(n=0;n<k;n++){
printf("%c",myPro[n]);
removeComments(myPro);}
}
#include <stdio.h>
#include <string.h>
void removeComments(char pro[]){
int i=0,j=0,len=0,newLen=0;
char newPro[1000];

printf("%d",len);
while(i<len){
if((pro[i] == '/')&&(pro[i+1]=='*')){
i = i+2;
while(!((pro[i+1]=='*')&&(
i++;
i += 2;
}
newPro[j] = pro[i];
j++;
i++;
}
j=0;
newLen = strlen(newPro);
while(j<newLen)
printf("%s",newPro[j]);
}
void main(){

Iam not entering file name .Iam manually giving the program
Herre is the output i get.Please help
Enter your program

Use strstr to check if the line contains "/*" and "*/".
strstr function returns the pointer of the location where /* is found. So u can copy the contents until /* using strncpy. (see man pages). It is easy
Hope that helps

This code is working fine in my system
#include<stdio.h>
#include<string.h>
/* This program is used for filtering the log files */
int main(void)
{
char *ptr, *index;
char array[20][500];
char line[1000];
int num,len,i,length;
num = 0;
while(gets(line))
{
ptr = index = line;
if(index = strstr(ptr,"/*")) {
len = index - ptr;
if ( len > 0 ) {
strncpy(array[num],ptr,len
length=strlen(array[num]);
array[num][length+1] = '\0';
num++;
}
}
else {
strcpy(array[num], ptr);
num++;
}
}
for(i=0; i<num; i++) {
printf("%s\n",array[i]);
}
}
It stores the lines in an array.
Well i havent checked for the end of comment and for other types of comments
You can add your own conditions to it

char array[20][500];

int num,len,i,length;
num = 0;
while(gets(line))
{
ptr = index = line;
if(index = strstr(ptr,"/*")) {
len = index - ptr;
if ( len > 0 ) {
strncpy(array[num],ptr,len
length=strlen(array[num]);
array[num][length+1] = '\0';
num++;
}
}
else {
strcpy(array[num], ptr);
num++;
}
}
for(i=0; i<num; i++) {
printf("%s\n",array[i]);
}
}

Tahanks very very much for the modified code .It is working properly now
Your code seems to get file names, but then it doesn't open each one to interogate the contents. Instead, it looks like it's trying to remove comments ( /* and not lines that begin with //) from the filename.
Once you get each filename, you should call fopen and then fgets to see if you have comments or not. This should be done before your while(i<len) loop in the removeComments function.
Good luck!
