Discussion Forum : Input / Output - Point Out Errors (Q.No. 1)
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;
}
Answer: Option
Explanation:
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.

Why the compilation of a program from one compiler to another compiler varies (some times) ? we need output which accepts globally. But in some perspectives it may not.

Char is keyword. It cannot be redeclared.

Syntax is correct but unsigned int leads to infinite loop while checking EOF(-1).

What do you mean by unsigned char; in this program ?

It works in Turbo C, but only if declared at the beginning of main...
