This is my C language assignment. Please help me to solve this. Thank you.

Task: please complete the following program. One of execution examples is also shown in this page. The purpose of the program is judging whether the file exits or not based on a given file name. #include ./a.out File name: abc.txt The file abc.txt doesn't exist. int main(void) { /*...*/ /* declare a file pointer fp*/ char fname[256]; printf(File name: "); scanf("%s, /*...*/); /*...*/ /* open the file and return to the file pointer fp*/ if (/*...*/) printf(The file (%s\ doesn't exist. , fname); else{ printf(The file \"%s\ exists. , fname); /*...*/ /* close the file */ } return 0; Be careful, the file should be in the same directory/folder as the program
