Begin by identifying the complete set of "special characters". Then use a Convert() function to replace them with a zero-length string.

those special charecters are not constent our sorce as files because of that i am getting different type of non keyboard special charecters.
only one thing i have to do other than A to Z and 0 to 9 remaining charecters i need to remove from the string .
how to do that please guide me.

This is a parallel routine that i wrote. And meets your requirement.
Code: Select all
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
char* DeleteChars(char *inputstring)
{
char *OutPut= (char *)malloc (sizeof(char *));
int length = 0;
int StringLength = strlen(inputstring);
if (length == 0)
OutPut[length] = '\0';
else
{
while(*inputstring)
{
if ((*inputstring>= 32) && (*inputstring<= 126))
{
OutPut[length] = *inputstring;
length++;
}
inputstring++;
}
OutPut[length] = '\0';
}
return OutPut;
free(OutPut);
}
Hope this helps.

Just curious; where does the variable called "i" get its value? You test it in

Copy paste error. I changed it in the post. Tested it and it is working.

I remember building something like this a while back. Check the following post for reference.

Bugfree, get rid of
free(OutPut); from you code as it will never be executed. The engine will take care of freeing the memory.

I have read somewhere in the forum that the memory has to be explicitly handled in the parallel routine. so the free(OutPut). I dint know that the parallel engine will take care of the memory clean up.

It is true that memory management needs to be handled but no statements after a "Return" statement gets executed, hence the request to get rid of it.
