Answer #1

void replace_chr(char *str, char a, char b){
    if(*str){
        if(str[0] == a)
            str[0] = b;
        replace_chr(str+1, a, b);
    }
}

Write a program that replace repeated three characters in a string by the character followed by 3. For example, the string aabccccaaabbbbcc would become aabc3ca3b3cc. When there are more than three repeated characters, the first three characters will be replaced by the character followed by 3. You can assume the string has only lowercase letters (a-z). Your program should include the following function: void replace(char *str, char *replaced); Your program should include the following function: void replace(char *str, char *replaced);...
