C programming. If I am using fgets(line, MAXLINE, stdin) function in a loop, should I zero-out line each time before a new iteration? -

if using fgets(line, maxline, stdin) function in loop, should zero-out line each time before new iteration? meaning have smth 

char *line = calloc(maxline+1, 1);     while (fgets(line, maxline+1, stdin)) {         ...     }

is required reallocate or zero-out line char string before next call of fgets?

thank

no. fgets guarantees 0 termination on successful read. loop condition handles unsuccessful case. completeness, should check calloc worked though.
