remove substring and character

[nyc680]

for this c program, i'd like to remove the substring "cc" and character "=" from input string "aaccbbccdd " the code below can only remove "cc" once, can somebody help me figure out how to remove other "cc" in the string also how to remove multiple character '=' ?

#include <stdio.h>
#include <string.h>


char *Mystrcpy1(char *s, const char *cs);
void func1(char *src, char *sub);

int main(void)
{
char s[32], *substr = "cc";


Mystrcpy1(s,"== aaccbbccdd");
printf("From the string: \"%s\"\n",s) ;
printf("We will attempt to remove substring \"%s\"\n",subst r);
func1(s,substr) ;
printf("Using function Mystrcpy1. The result: \"%s\"\n\n", s);

return 0;
}


char *Mystrcpy1(char *s, const char *cs)
{ /* Copy from beginning of string cs to the end */
char *s1;
const char *cs1;


for(s1 = s,cs1 = cs; '\0' != (*s1 = *cs1); s1++,cs1++) ;
return s;
}



void func1(char *src, char *sub)
{ /* Using function Mystrcpy1 */
char *p;


if ((p=strstr(src, sub)) != NULL)
Mystrcpy1(p,p+s trlen(sub));
return;
}

Hi,
You have to call your replace function till you find a substring in your code that is till strstr returns NULL.
After doing replacement of cc you shuld call your function in the same way to replace =.
