Remove Asterisks from C Strings

You can write a function to remove asterisks at the beginning and end of a string, following these steps:

  1. Create a function, for example removeStars, which takes a string as a parameter.
  2. Use a while loop to iterate through the string and find the position of the first non-asterisk character, which is then labeled as start.
  3. Using a while loop to iterate through the string in reverse order, find the position of the first non-asterisk character and label it as “end”.
  4. Extract the substring between start and end using the substr function, which is the string with the leading and trailing asterisks removed.
  5. Return the string without the leading and trailing asterisks.

Here is an example code:

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

char* removeStars(char* str) {
    int start = 0;
    int end = strlen(str) - 1;

    while(str[start] == '*') {
        start++;
    }

    while(str[end] == '*') {
        end--;
    }

    return str + start;
}

int main() {
    char str[] = "****Hello, World!****";
    char* result = removeStars(str);
    printf("Result: %s\n", result);

    return 0;
}

In the example above, the removeStars function will eliminate the leading and trailing asterisks from the string ‘str’ and return the modified string.
