Point out the error/warning in the program?
#include<stdio.h>
int main()
{
unsigned char ch;
FILE *fp;
fp=fopen("trial", "r");
while((ch = getc(fp))!=EOF)
printf("%c", ch);
fclose(fp);
return 0;
}
Answer: Option
Explanation:
Here, EOF is -1. As 'ch' is declared as unsigned char it cannot deal with any negative value.
