Using fgets() with char* type

Question

I have a simple question about using fgets() with char* string.

....
char *temp;
FILE fp=fopen(\"test.txt\", \"r\");

fgets(temp, 500, fp);
printf(\"%s\", te         


        

Answer 1

When we write

char *temp ; 

it means temp is an uninitialized pointer to char i.e. currently it does not contain any address in it .

While using fgets you have to pass a string in which the bytes read from file pointer is to be copied . link since the temp is uninitialized , the fgets looks like this

fgets( , 500 , fp ) ;

which is invalid .

Hence , we should give initialized string which can be formed as :

1) char *temp = malloc(sizeof(500)) ;
or
2) char temp[500] ;

Hence if we pass initialized string to fgets , it would look like

fgets( < some string > , 500 , fp) ;
