My code has a segmentation fault which I can't figure out why.

#include #include #include

char* alphabets(char string[]){ char *new_string;

for(int i = 0;string[i]!='\0';i++){ if(isalpha(string[i])){ new_string[i]=string[i]; } }

return new_string; }

int main() { char test[]="Hello, World!"; char *new_arra=alphabets(test); printf("%s",new_arra); printf(" ");

return 0; }
