1. Point out the error in the program? #include<stdio.h> #include<stdlib.h> int main() { unsigned char; FILE fp; fp=fopen("trial", "r"); if(!fp) { printf("Unable to open file"); exit(1); } fclose(fp); return 0; }

This program tries to open the file trial.txt in read mode. If file not exists or unable to read it prints "Unable to open file" and then terminate the program. If file exists, it simply close the file and then terminates the program.
